Question: Does it work?
Document: This is a great product. I have used it for years. It is great for the glutes and easy on the knees. A great workout. Very portable form place to place in my home. I dont use the bands too much. The air mechanism is easy to work and very convenient. The timing device is a great addition. Hope you never stop making it.
I got this as a gift and while it's a great idea and may work for some, it did not work for me. I am 120 pounds and I could not get the steps to go down without putting my entire body weight on each of them and then waiting what seemed like forever for them to go down, so I never got a good rhythm going. I really liked the arm exercise bands though.
It's so much fun, and the noise is very slight, just the pumping of the air, just turn up the tv and you won't notice. It was VERY challanging the first time, I olny logged on 15 minuted, but by the second day I was able to double that to 30. :) Tip: work your way up to using the resistance bands, or start out by using very light hand weights like you would for jogging. Its a blast! ENJOY!!! :)
this was a fastshipping and very good quality of merchandise even more good the price and came with everything you see in the ad
lightweight,portable,fun....
i can't get the air inside de steps , try to pull the dam thing up and made a hole on it
i am only 100 lbs and was 115 when i bought it so i can say how it will perform for someone heavier. but i really love this product and have never had an issue with it in 5 years.
bought this about 5 yrs ago off the TV for $100. best money i ever spent. i know some ppl have had issues with it being plastic and being loud. mine has lasted 5 years and i use it pretty regularly. i do it while watching tv a lot. sure its on the loud side making a swish swish noise but i don't mind. i love the stepper. i feel it in my butt and legs and i think its a nice cheap alternative to a more heavy duty stepper.
Works great!!! What i needed for my workout. It was just as advertised. Use it every day and no problems
This is the best $50 I've ever spent, I purchased this unit at walmart after much research.
