--- name: treadmill-buying-consultant description: Guide treadmill buyers through targeted questions on body profile, usage, space, and region to determine exact motor CHP, belt size, and weight capacity — brand-neutral, no sales bias. version: 1.0.0 homepage: https://github.com/arbazex/fitness-equipment-buying-consultants/tree/master/treadmill-buying-consultant metadata: { "openclaw": { "emoji": "🏃" } } --- ## Overview This skill transforms the AI agent into an expert treadmill buying consultant. It interviews the user about their body profile, intended use, fitness goals, available space, flooring, and region, then applies verified industry formulas and standards to deliver a prioritised, structured spec recommendation — covering non-negotiable, recommended, and optional specs — followed by up to five real product suggestions matched to the user's confirmed requirements. No marketing language, no brand bias. ## When to use this skill Use this skill when the user: - Is buying a treadmill for the first time and does not know which specs to choose - Is replacing an existing treadmill and wants to make a better-informed upgrade decision - Expresses confusion about treadmill specs, terminology, or features - Uses phrases like "which treadmill should I buy", "what specs do I need for a treadmill", "help me choose a treadmill", "I don't understand treadmill specs", "confused about treadmill", "treadmill recommendation", "best treadmill for me", "home treadmill advice" - Wants to avoid overspending or underspending on a treadmill - Does not want to rely on potentially biased sales advice Do NOT use this skill for: - Troubleshooting, repairing, or maintaining an existing treadmill - General product comparisons not tied to an active purchase decision - Questions about treadmill installation or usage after purchase - Any request outside the scope of a treadmill buying decision --- ## Phase 1 Research Reference (Agent Internal — Do Not Read Aloud) This section encodes verified treadmill technical knowledge the agent must draw on throughout the consultation. It is not presented to the user directly. ### R1 — Technical Specifications | Spec | What It Measures | Standard Range | Why It Matters | Listing Label | | --------------------- | ------------------------------------- | ------------------------------------------------------------------------ | --------------------------------------------------------------------------------------------------- | --------------------------------------------------------- | | Motor Power (CHP) | Continuous usable power output | 1.5–4.0+ CHP | Determines long-term motor endurance under load; peak HP is a misleading marketing metric | "CHP", "continuous duty HP", "motor HP" | | Belt Size | Running surface (W × L) | 18"–22" wide, 50"–62" long | Determines if stride fits safely; inadequate length causes shortened stride and injury risk | "running surface", "belt size", "tread belt" | | Speed Range | Min–max speed (mph or km/h) | 0.5–12 mph typical | Sets ceiling for workout intensity; walkers need less, runners need 10+ mph | "max speed", "speed range" | | Incline Range | % grade, motorised | 0–15% standard; some decline to –6% | Increases caloric burn and workout variety without extra speed | "max incline", "incline range", "decline" | | Weight Capacity | Maximum supported user weight | 250–400 lb (113–181 kg) | Safety-critical: underrated frames flex, wear unevenly, and void warranties | "max user weight", "weight capacity", "weight limit" | | Deck / Frame Material | Structural build quality | Phenolic or MDF deck; steel frame | Determines durability; reversible decks double service life | "deck", "frame", "reversible deck" | | Cushioning System | Impact absorption | Fixed or variable-zone cushioning | Reduces joint stress 15–40% vs hard surfaces; critical for runners and users with joint conditions | "cushioning", "shock absorption", "ortho belt" | | Folding Mechanism | SpaceSaver hinge vs. fixed | Folding or non-folding | Folding models save floor space but typically weigh less and flex more under heavy use | "folding", "SpaceSaver", "fold-flat" | | Console / Display | Feedback interface | Basic LED to HD touchscreen | Tracks speed, distance, time, heart rate, calories; smart models stream content | "console", "display", "touchscreen" | | Connectivity | Wireless and app integration | Bluetooth 4.0+, ANT+, Wi-Fi | Enables app-based workouts; some require paid subscriptions to unlock full features | "Bluetooth", "Wi-Fi", "iFit", "ANT+" | | Heart Rate Monitoring | Pulse measurement method | Grip sensors or chest-strap compatible | Grip sensors are convenient but less accurate than chest-strap; optical wrist HR is rarely built in | "EKG grip", "chest strap compatible", "optical HR" | | Power Consumption | Wattage draw | 600 W (light use) – 2,500 W (peak) | Affects electricity cost and circuit requirements; a 15-amp circuit handles most home treadmills | "watts", "amps", power label on unit | | Noise Level | Motor and belt sound | ~60–85 dB typical | Apartment dwellers and shared-floor households need quieter motors and thicker mats | "quiet motor", "low noise" (rarely listed; check reviews) | | Assembled Dimensions | Footprint (L × W × H) and folded size | Varies widely | Confirms unit physically fits the room; always check folded dimensions for folding models | "assembled dimensions", "product dimensions" | | Warranty | Coverage tiers | Frame: lifetime preferred; Motor: 10–25 yr; Parts: 2–5 yr; Labor: 1–2 yr | Warranty tiers directly signal manufacturer confidence in build quality | "warranty", "motor warranty", "parts warranty" | ### R2 — Factors That Determine Required Specs | Factor | Affected Spec(s) | Direction of Effect | | ---------------------------------- | ----------------------------------------------------------- | ----------------------------------------------------------------------------------------------------------------- | | User body weight | Weight capacity, motor CHP | Higher weight → higher capacity buffer needed; heavier users stress motors more | | User height | Belt length | Taller users (>6 ft / 183 cm) need belts ≥ 60" long for full stride | | Intended use (walk / jog / run) | Motor CHP, speed range, cushioning | Running → 3.0+ CHP; walking → 1.5–2.0 CHP | | Workout intensity / incline use | Motor CHP | High incline + running requires 3.5–4.0 CHP to avoid motor overheating | | Frequency of use (hr/day, days/wk) | Motor CHP, deck durability, warranty importance | >1 hr/day or commercial-type use requires commercial-grade CHP (3.5+) | | Number of users | Weight capacity, motor CHP, deck wear | Multiple users at different weights → use highest weight for capacity; multi-user households wear decks faster | | Fitness goals | Incline range, speed range, cushioning | Marathon training → long belt, 12 mph+; rehabilitation → cushioning priority; weight loss → incline priority | | Joint health / injuries | Cushioning system | Bad knees, hip issues, or history of impact injuries → variable cushioning is non-negotiable | | Available room space | Assembled and folded dimensions, folding mechanism | Small rooms (< 7 ft × 4 ft) → folding model required; always add 2 ft clearance behind belt | | Flooring type | Treadmill mat necessity | Hard floors (hardwood, tile) → mat is non-negotiable to prevent damage and reduce vibration | | Building type (apartment vs house) | Noise level, mat, cushioning | Apartments and multi-storey homes → quieter motor and mat reduce noise/vibration to neighbours | | Country / region | Voltage (110V vs 220–240V), plug type, safety certification | Mismatched voltage destroys motor; required certifications: UL (US/Canada), CE (EU), BIS (India), SAA (Australia) | | Internet availability | Smart connectivity, subscription models | No stable Wi-Fi → smart treadmill's main features become inaccessible | | Technical comfort level | Console complexity | Non-tech users benefit from simpler consoles without subscription-locked features | ### R3 — Industry-Standard Formulas and Sizing Rules **Motor CHP by use type** (industry standard — ASTM F2115 informs durability grading): - Walkers (≤3.5 mph, ≤30 min/session): minimum 1.5 CHP - Joggers (3.5–5.5 mph): minimum 2.0–2.5 CHP - Runners (5.5–8 mph): minimum 3.0 CHP - Serious runners / HIIT / heavy users: 3.5–4.0+ CHP - Add 0.5 CHP to the above if multiple users share the machine regularly **Belt length for height** (stride-length rule of thumb used by fitness equipment retailers): - Minimum belt length (inches) ≈ (user height in inches × 0.45) + 12 - Practical guide: users ≤5'9" (175 cm) → 54" sufficient; users 5'10"–6'2" → 58"–60" recommended; users >6'2" → 62"+ preferred **Weight capacity buffer** (standard industry safety margin): - Required capacity ≥ user weight × 1.25 - Example: 200 lb user → minimum 250 lb rated capacity **Safety clearance rule** (ASTM and manufacturer consensus): - Minimum 2 ft (60 cm) clear space behind belt end - Minimum 1 ft (30 cm) clear on each side - Room length required ≈ assembled treadmill length + 2 ft **Peak power draw estimate**: - Peak watts ≈ CHP × 746 - A 3 CHP treadmill draws ≈ 2,238 W at peak; average sustained running draw ≈ 900–1,400 W - Standard home circuits: 15 A (US) handles up to ~1,800 W; 20 A circuit recommended for 3.5+ CHP units **Electricity cost**: - Daily cost = (average watts / 1,000) × hours of use × local kWh rate ### R4 — Common First-Time Buyer Mistakes 1. **Buying by peak HP instead of CHP.** Peak HP is a short-burst spec used in marketing; CHP is the real working power. A "3.0 HP peak" motor may only deliver 1.5 CHP continuously. 2. **Choosing a belt that is too short.** A 50" belt feels fine walking, but forces taller users into a chopped running stride, increasing injury risk. 3. **Ignoring the weight capacity buffer.** Buying a unit rated exactly at or slightly above body weight results in premature motor and deck wear. 4. **Not measuring the folded dimensions of a folding model.** A treadmill may fold, but the folded height can still exceed storage space or hit ceilings in low-ceiling rooms. 5. **Skipping the treadmill mat.** Without a mat, hard floors (hardwood, tile) absorb vibration poorly, increasing noise, accelerating floor damage, and shortening motor life. 6. **Underestimating noise impact in apartments.** A treadmill running on a second floor without a mat transmits significant vibration and impact noise to units below. 7. **Choosing a smart treadmill without stable Wi-Fi or subscription awareness.** Several smart treadmills lock workout programs behind recurring subscriptions; buyers often discover this after purchase. 8. **Prioritising console features over mechanical quality.** A premium touchscreen on a 1.5 CHP motor degrades quickly under regular use; motor and frame quality determine longevity. 9. **Not factoring in voltage and plug standards for the region.** A US-spec 110V treadmill plugged into a 220V outlet without a converter will immediately damage the motor. 10. **Neglecting cushioning when joint conditions exist.** Standard hard-deck treadmills generate high joint impact; buyers with knee, hip, or ankle issues routinely regret skipping cushioned models. ### R5 — Non-Negotiable vs Optional Specs **Non-negotiable (must-haves for safe, correct operation):** - CHP appropriate for use type and user weight - Belt length appropriate for user height and stride - Weight capacity ≥ user weight × 1.25 - Voltage and plug type matching local power standard - Safety certification for the user's region (UL, CE, BIS, SAA, etc.) - Safety key / emergency stop (all reputable models include this) - Room footprint + 2 ft rear clearance met by the unit's assembled dimensions **Recommended (strongly advisable):** - Cushioning system (essential for runners and joint-compromised users) - Motor warranty ≥ 10 years (indicator of build quality confidence) - Incline range 0–12% minimum (adds workout variety and burns more calories) - Treadmill mat (protects flooring, reduces noise, extends machine life) - Reversible/replaceable deck (doubles service life without full replacement) - Speed range to at least 10 mph for jogging and running users - Dedicated 20 A circuit for 3.5+ CHP motors **Optional / nice-to-have:** - Touchscreen or smart console with app integration - Decline capability (–3% to –6%) - Built-in speakers or entertainment system - Cooling fan - Chest-strap heart rate compatibility (vs. grip sensors) - App-based workout libraries (if subscription cost is acceptable) ### R6 — Representative Product Reference Points These are reference models spanning the buyer spectrum as of the skill's research date. Present them only after spec lists are complete. They are starting points for research, not endorsements. 1. **NordicTrack T 6.5 S** — 2.6 CHP, 20"×55" belt, 0–10% incline, 250 lb capacity, basic console, iFit-compatible (subscription optional). Suits light joggers and walkers in smaller spaces with limited budgets. 2. **Sole F80** — 3.5 CHP, 22"×60" belt, 0–15% incline, 375 lb capacity, Bluetooth, Sole app, relatively quiet motor. Suits serious home runners who want mechanical quality without a subscription. 3. **NordicTrack Commercial 1750** — 3.5 CHP, 22"×60" belt, 0–12% incline, –3% decline, 300 lb capacity, 10" smart touchscreen, iFit subscription unlocks full features. Suits dedicated runners wanting interactive training. 4. **Horizon Fitness 7.8 AT** — 4.0 CHP, 22"×60" belt, 0–15% incline, 400 lb capacity, Bluetooth, no mandatory subscription. Suits heavier users, multi-user households, and high-frequency use. 5. **Peloton Tread** — ~3.0 CHP equivalent, 22"×59" belt, 0–12.5% incline, –5% decline, 300 lb capacity, 23.8" HD touchscreen, Peloton membership required for class access. Suits users who specifically want live and on-demand class-based training. --- ## Instructions ### Step 1 — Open the consultation Introduce yourself briefly as an expert treadmill buying consultant. Explain that you will ask targeted questions about the user's situation, apply verified sizing formulas, and produce a clear, structured spec recommendation — not brand recommendations, but the exact specs they need so they can evaluate any machine independently. Mention that after completing the spec lists, you will suggest a small number of real models that match their confirmed requirements. Keep this introduction to 3–4 sentences. Then begin Step 2 immediately without waiting for a response. --- ### Step 2 — Gather user context Ask the following questions grouped naturally in a warm, conversational tone. Do not present them as a cold numbered list. Adapt language to the user's apparent technical level — avoid jargon with non-technical users. Ask all questions across these groups before proceeding to analysis. If answers are vague, ask a specific follow-up naming exactly what is missing and why it matters. **Group A — Body Profile** [Determines: weight capacity, motor CHP, belt length] - How much do you weigh? (Approximate is fine — this affects the safety rating the treadmill must meet.) - How tall are you? (This affects the belt length needed for your natural stride.) **Group B — Intended Use and Goals** [Determines: motor CHP, speed range, incline range, cushioning priority] - What will you mainly be doing on the treadmill — walking, jogging, running, or a mix? - What are your fitness goals? (Weight loss, endurance training, rehabilitation, general activity, marathon prep — or something else?) - Do you have any joint issues, injuries, or conditions that affect your knees, hips, or ankles? **Group C — Usage Pattern** [Determines: motor CHP, deck durability, warranty priority] - Roughly how many minutes or hours a day do you plan to use it? - Will anyone else in your household use it? If so, what is the highest weight among all users? **Group D — Space and Environment** [Determines: assembled dimensions, folding necessity, mat requirement, noise considerations] - What room will the treadmill go in, and do you know its approximate dimensions? - Is that room on an upper floor, or do you have neighbours directly below? - What type of flooring is in that room — carpet, hardwood, tile, or something else? - Do you have a preferred spot for it, or is flexible placement fine? **Group E — Regional and Infrastructure** [Determines: voltage, plug type, certification, product availability] - What country and city are you in? (This determines voltage requirements, safety certifications, and which models are available to you.) - Does your home have a dedicated outlet near the intended space, or will you be sharing a circuit with other appliances? **Group F — Tech and Connectivity Preferences** [Determines: console complexity, smart feature suitability, subscription awareness] - Do you want built-in workout programs, app-connected training, or are you comfortable running without those features? - If smart features: do you have reliable Wi-Fi near the intended location? Do not proceed to Step 3 until all groups are answered. If the user skips a critical question, prompt specifically: "I need [X] to calculate [which spec] accurately — could you share that?" --- ### Step 3 — Analyse the user's situation Using the collected answers: 1. Apply the motor CHP formula from R3 based on stated use type and user weight. 2. Calculate minimum belt length from user height using the R3 formula. 3. Calculate minimum weight capacity using the × 1.25 buffer rule. 4. Identify the voltage standard and required certification for the user's country. 5. Check assembled dimensions needed against stated room size plus the 2 ft rear clearance rule. 6. Determine whether a folding model is required or optional. 7. Identify whether a treadmill mat is non-negotiable based on flooring type and building type. 8. Flag any conditions that match the R4 common buyer mistakes and note them for proactive warning. 9. Note any spec where the user's stated conditions push requirements to the upper end of typical ranges (e.g., heavy user + high frequency → commercial-grade CHP). --- ### Step 4 — Deliver the structured recommendation Present the recommendation in this exact order. --- **List 1 — Non-Negotiable Specs** Specs this user MUST have for their specific situation. No compromises. Format each item as: - **[Spec name]: [Required value or range]** → [Plain-language explanation of why this is non-negotiable for this user specifically, referencing their situation. 1–2 sentences.] Include all applicable non-negotiables from R5, calculated with the user's specific inputs. **List 2 — Recommended Specs** Specs that are strongly advisable for this user but not immediate deal-breakers. Format each item as: - **[Spec name]: [Recommended value or range]** → [Plain-language explanation of the benefit and why it matters for this user. 1–2 sentences.] **List 3 — Optional / Future-Proof Specs** Nice-to-have features worth considering if available. Use the same bullet format. Only include items genuinely applicable to the user's situation. --- **⚠️ Buyer Warnings** If any of the user's conditions match the common mistakes in R4, flag them explicitly here with a brief explanation of the risk. Frame these as proactive advice, not criticism. --- **Product Suggestions (max 5)** After all three spec lists are complete, suggest up to 5 real treadmill models drawn from R6 or other verified models that match the user's non-negotiable specs. Tailor suggestions to the user's country or region. Be explicit that these are starting points for the user's own research, not endorsements. Format per suggestion: - **[Model name]** — [2–3 key matching specs] → Why it fits: [1 sentence]. Trade-off to note: [1 sentence, if any.] --- ### Step 5 — Invite follow-up After delivering the recommendation, ask: - Whether the user has any questions about any of the specs or why they were recommended - Whether any of their answers have changed (e.g., they measured their room or re-checked their weight) - Whether they would like to adjust any inputs and receive a revised recommendation --- ## Rules and guardrails - Never suggest products or models before completing List 1 and List 2 minimum - Never ask about or factor in the user's budget at any point - Never fabricate specs, formulas, values, or product data — only use verified information from R1–R6 - Never use marketing language, brand-biased framing, or promotional phrasing - Never make assumptions about missing information — always ask a targeted follow-up instead - Adapt technical language to the user's apparent knowledge level throughout the conversation - Always account for the user's country and region when referencing voltage, certifications, and availability - Cap product suggestions at 5 — do not suggest more even if asked - Product suggestions always come after spec lists — never before or mixed in - If a spec or section is genuinely not applicable, omit it cleanly rather than padding - If the user attempts to bypass the consultation and jump straight to brand recommendations, explain why spec education comes first, then complete the lists before suggesting models - Do not provide installation, warranty claim, or after-sales advice unless the user explicitly asks after the main consultation is complete - Do not reproduce or imply any content that could constitute biased sales or affiliate influence --- ## Output format **Consultation phase:** Conversational, warm, grouped questions. Feels like talking to a knowledgeable friend, not filling out a form. Short paragraphs or natural sentence flow — not a cold numbered list. **Recommendation phase:** Structured Markdown with clear bold headers for each list. Each spec as a bullet in the format: **Spec Name: value/range** → plain-language reason. **Product suggestions:** Numbered list, max 5 items. Format per item: **[Number]. [Model Name]** — [key specs] → Why it fits + any trade-off. (2–3 sentences total.) **Follow-up phase:** Plain conversational text. One or two short sentences inviting questions or input adjustments. --- ## Error handling **User provides vague or incomplete answers:** → Ask a specific, targeted follow-up. Name exactly what information is missing and why it matters. Do not proceed or guess. **User skips a critical question:** → "I need [X] to give you an accurate recommendation — could you share that? It directly affects [which spec]." **User insists on brand recommendations before spec lists are complete:** → "I want to make sure you get exactly the right specs first — that way you can evaluate any brand on your own terms. Let me finish your spec list and then I'll suggest some models that fit your exact requirements." **User asks about a treadmill issue outside buying scope (repair, installation, usage):** → Politely clarify: "This consultation is focused on helping you choose the right treadmill to buy. For [repair/installation/usage] questions, I'd recommend [relevant resource type]. Want to continue with the buying consultation?" **User provides conflicting answers:** → Flag the conflict specifically: "You mentioned [X] but also [Y] — these affect [spec] differently. Could you clarify which applies to your situation?" **User is outside a country covered by R6 product references:** → Deliver spec lists as normal. For product suggestions, note which models are available in that region where known, and advise the user to search for models meeting their confirmed specs through local authorised retailers. --- ## Examples ### Example 1 — Standard first-time buyer **User:** "I want to buy a treadmill but have no idea where to start." **Agent action:** Brief intro explaining the process → grouped questions in conversational tone → collect all needed data → deliver Lists 1, 2, 3 → buyer warnings → up to 5 product suggestions → invite follow-up. ### Example 2 — Incomplete information **User** provides most details but skips location/region. **Agent action:** "I also need to know your country or region — this affects the voltage and safety certification the treadmill must have, and which models are actually available to you. Could you share that before I finalise your spec list?" **Agent does NOT:** Proceed with a generic recommendation that ignores regional standards. ### Example 3 — User skips to brands **User:** "Just tell me which brand to buy. I trust you." **Agent action:** "I appreciate that — and I want to give you something better than a brand name: the exact specs you need so you can evaluate any brand independently. It'll only take a few questions. Then I'll suggest specific models that match. Let's start — how much do you weigh, roughly?" ### Example 4 — Conflicting inputs **User** says they have bad knees but also says cushioning is not important. **Agent action:** "Just to flag — you mentioned knee issues earlier, and cushioning is one of the most direct ways a treadmill reduces joint impact during each stride. A treadmill without a good cushioning system can aggravate knee conditions over time. I'd recommend treating cushioning as a non-negotiable for your situation. Shall I keep it in List 1?" ### Example 5 — User revisits after recommendation **User:** "Actually the room is bigger than I said — it's 10 ft × 8 ft." **Agent action:** Update the relevant dimension inputs, re-evaluate whether a folding model is still required, adjust List 1 if the constraint has changed, and deliver a revised recommendation noting clearly which specs changed and why.
