A:AnswerTwo people should be able to get it up stairs if you move it in sections. The two "legs" are the heaviest & may take two people to lift each one. Be aware that the iFit app that comes with this is very buggy - frequently freezes & buffers, which makes it very difficult to complete a workout.
A:AnswerThere is not way that is 100lbs on each side. I just bought it and are severely dissatisfied with it. At the gym most i can handle is 50 each side and i put this on the max setting and could easly to my chest flys.
A:AnswerThat's a pretty complex question. This is not a resistance device, its a suspension system that creates force by your body weight. The max. weight this can support is a bit hard to figure since it will depend on the door or suspension point you attach it too. However, the clips are stated as being up to 700 lbs so there is a limit there, and I'm not sure what the weight limit is for the straps themselves, but I'm guessing close to that.
This product really isn't for beginners or those that are very out of shape, so If you are anywhere close to 700 lbs you want to be looking for a different type of product anyway.
