I just do hindu squats and jump squats with this. I''m 6''4" and I haven''t had a problem with the black cover sliding around. It''s always pretty tight across my shoulders. Maybe it slides for shorter folks when in the squatting position, but for me, no movement.
It appears well constructed. I''ll update if I notice any tears in the band. However, so far so good.

I''m 37 years old, this is by far the best tool for vertical jump training. I still love to Box Squat with bands, do weighted DB jumps and use Jumpsoles. But the PPJ is the most natural thing because it doesnt restrict any of your moviements and provides great resistance. I suggest you start off with just one band. Only use two bands once you get too strong for it. Any jump exercise you can think of, you can probably use the PPJ. I love doing Depth Jumps and Sprints with the PPJ!Read Best Reviews of Lifeline USA Portable Power Jumper Here
I own many lifeline producs and am happy with all. The power jumper is no exception it''s well designed and can help you increase your verticle. I did not follow the hardcore training routine that it suggests in the training DVD (it is sold seperately but I think that it should be included with the power jumper) but felt like it helped my verticle a little. I am an avid basketball player that is getting a little older and while I was never a strong jumper I felt like this could give me a little bit of added spring. It did and if I used it more it would probably give better results.Want Lifeline USA Portable Power Jumper Discount?
I will say that I''m a fan of almost all Lifeline products (the ab wheel is the only exception as it is no different than any other ab wheel at several times the price).The power jumper is certainly among the best of their offerings. It can be used for jump training, running training (with the exertion on the down step), a supine leg press, and other exercises.
As other reviewers have stated, the item only comes with two padded supports and they do have the tendency to shift around while using the power jumper.
Additionally, it has slots for three tubes which range from 10 lbs. 100 lbs. peak resistances in ten pound increments.
