I work from home for the business i started recently, so i wanted some form of working out while i am working.. I mainly bought this machine for two functions, one for working out from my office while working, and the other for the fact this machine can be used for arm exercising. I noticed that the product listing mentions that its for elderly people, but i am a 35 year old fit man, and this product works perfectly for me! There is a tiny bit of installation, but its a breeze, you only have to screw a few things on and it provides the tools you need to do so. The machine comes with a controller so if you are working while using it, you can easily change the speed and direction without having to get up or move. The controller is definitely a bonus, and really useful. The machine itself has a lit up digital screen which is nice and bright. The arm exercise function is amazing, its my favorite part. Inside the product box also is very easy to read and follow instructions which also explains how to do a few different workouts with the machine. Overall, this is a great purchase for anyone trying multitask at work and burn some serious calories.
