in the profile screen add calendar workout/exercise heatmap:
Here’s a detailed plan for the Calendar Workout/Exercise Heatmap concept, breaking it down into different categories and making sure that all the data is represented visually through heatmaps, colors, and metrics. This concept helps track and visualize workouts over time, offering insights into progress and areas for improvement. Here's a detailed breakdown:

1. Heatmap Structure
Base Calendar Layout : Each day is represented as a cell in a calendar orrowofdays. The color intensity within each cell visually reflects data about the workout done that day.
Multiple Layered Heatmaps : Each workout category Cardio,StrengthTraining,etc. has its own heatmap or color overlay. Users can toggle between different categories or view them stacked.
2. Workout Categories & Heatmaps
a. Cardio Heatmap
Color Gradient : Based on time spent doing cardio exercises like running, cycling, swimming, HIIT, or rowing.
Light Color: Short duration e.g.,10−20min
Darker Color: Longer duration e.g.,60+min
Overlay Data : Display metrics like heart rate zones or calories burned with numbers or symbols within the heatmap cell.
Heart Rate Zones : Color shift based on time spent in each zone e.g.,Blue=Zone1,Red=Zone5.
b. Strength Training Heatmap
Color Gradient : Based on volume of reps, sets, and weight lifted.
Lighter Color: Lower volume e.g.,3setsof8reps.
Darker Color: Higher volume e.g.,5setsof12reps.
Muscle Group Focus : Each strength training session can be broken down into:
Upper Body : Chest, Shoulders, Back, Arms.
Lower Body : Legs Quads,Hamstrings,Calves,Glutes.
Core : Abs, Obliques, Lower Back.
Toggle Option : User can toggle between muscle groups to view specific heatmaps for the focus of the workout.
c. Flexibility/Recovery Heatmap
Color Gradient : Used for activities like yoga, stretching, mobility, or rest days .
Light Color: Shorter session or light stretching 10−20min.
Darker Color: Longer yoga sessions or rest days for full recovery.
Rest Day Markers : Use a distinct light gray or blue for rest days to ensure they are visually separated from active days.
Mobility Focus : Sessions focusing on flexibility or recovery, with darker hues representing longer or more intense recovery sessions.
3. Metrics & Data Overlays
To add richer insights to each day’s workout, overlay the following key metrics within each calendar cell or hover popup.

a. Workout Duration
Visualized through intensity of the heatmap darkercells=longersessions.
b. Reps/Sets/Weight
For strength training, cells can display volume setsxreps or weight.
Overlay numbers can represent total weight lifted in a session e.g.,"Total:500kg".
c. Heart Rate Data
Average heart rate or time spent in different heart rate zones for cardio exercises.
Higher heart rate zones 4−5 could result in darker colors within the cardio heatmap.
d. Calories Burned
This metric can be a simple overlay number or bar chart embedded in each cell, representing calories burned during the session.
e. RPE RateofPerceivedExertion
A small number 1−10scale overlaid in the corner of each cell reflects how hard the workout felt on that day. This helps track how effort level fluctuates over time.
f. Personal Records PRs
Use a special symbol e.g.,astarorabrightcolor to mark personal records PRs in a given workout. This could be applied to any type of exercise, whether it’s a weightlifting PR or running distance PR.
4. Layering and Filtering
To make the heatmap intuitive and easy to navigate, users should be able to:

Toggle between workout types : Cardio, Strength Training, Flexibility/Recovery.
View muscle group focus : Upper Body, Lower Body, Core.
Customize timeframes : View heatmaps on a daily, weekly, or monthly basis.
Hover/Click for Details : Hover over any day to get a detailed popup showing the specific metrics for that session e.g.,exactduration,totalweightlifted,etc..
5. Color Scheme Ideas
Cardio : Shades of blue or red, shifting from light to dark based on intensity or duration.
Strength Training : Shades of green or orange, shifting with volume sets,reps,weight.
Flexibility/Recovery : Shades of purple, lighter for short sessions and darker for longer or more focused recovery periods.
PRs : Gold or bright yellow to make new records stand out.
6. Advanced Insights and Trends
To add depth to this system, it could offer:

Weekly Summaries : Aggregate total workout time, calories burned, and most frequently targeted muscle groups.
Monthly Progress Reports : Visual summaries showing PRs, calories burned, and time in different heart rate zones.
