Question: does it have  constant incline, or is it zero incline
Document: For Bowflex to claim that a user (any user) can burn over 600 calories in 30 minutes is complete BS. A marathon runner or a competitive cyclist doesn't burn 600 calories in 30 minutes!To compare calorie burn for the Treadclimber with calorie burn on a zero-incline treadmill is also nonsense -- if you put a treadmill at a comparable incline, calorie burn would be very similar or the same.The Treadclimber may be a legitimate piece of exercise equipment but with such exaggerated claims it's difficult to know.
You can do that on your own. I wish it did more for the money I spent. Another kicker is that the manual tells you to unplug your machine and if you do this it re-sets the go coach completely.5)The TC20 is the right machine for taller people (6'+)my husband is 6'4 and needs even bit of stride allowance on the machine.6)over all I love my machine. It is VERY sturdy. I am not burning 500 calories a session yet.
The product started out good but if it needs service, be prepared to do it yourself.I highly recommend not to buy this Chinese made product that is way over priced.If you are not handy with working with tools screwdrivers and rachets to repair it I reccomend you to buy from Sears which might be able to service the product!
Removing the mat also made it easier to keep the floor under the machine clean.Rubber chair tips (1") can be found any hardware store,  but the Waxman Appliance anti-walk pads I only found at Lowes [...]
Please don't give up.2)Start out slow and work your way up. I made it through half of the space needle in the beginning and under two weeks I am making it to the top.3)The motion of the machine is not hard to get use to. Even my 70 year old mother could use the machine on lower speeds.
Not even close to worth the money I payed for the machine. I have replaced the hydraulic rams 3 times now. The customer service has been very cooperative in having them replaced, so at least that is one good point about Bowflex as a company. The rams appear to be very poorly designed. I have attempted to adjust their movement tension as per the instructions with very little improvement if at all.
My husband and I both work in public service (law enforcement and EMS) and with our erratic schedules had found it difficult to make it to the gym with any regularity. Add to the fact that we just moved 20 minutes out of town with triple-digit Texas heat, we decided to purchase the TC20 and a bowflex blaze home gym. I ordered the tc20 online, directly from bowflex and the blaze was ordered through sears.
My TC20 arrived exactly one week after placing my order, which was sooner than I expected. After assembly, I was extremely disappointed when it started running erratically after 10 minutes of use (speeding up, slowing down, error code). I contacted the company and was told that the problem was a faulty circuit board and they shipped me an entirely new lower unit (and they didn't want the original one back, meaning I have spare parts for future use if I should need them).
It will record your previous exercise timings, but really what assistance is this?The workout itself is effective and I can honestly say that it is much easier on the body than a conventional thread mill. (Wear earbuds to buffer out the massive noise from the rams. )Overall a very disappointing piece of equipment I would not recommend this machine at the price they want for it.
It was very smooth and easy on the joints. The heart monitor worked well, it just took a minute or two to find the right spot for it to register. I have a short stride (I'm 5'2") but my husband is 6' and I'm glad we got the tc20 for the longer treadles for him. The display screen was as I expected from reviews I had read, but is sufficient for my needs.
Answer: yes
