This is great for training, I mean people of all levels benefit from this. And it's not too hard, that younger/newer gymnasts are able to use it. And it takes up very little room. Just against a wall it stands =p.

it was really good to get leg and arm strength.
Pros: good for a variety of exercises
This is great for different core and stretching exercises. We got one in our gym about a year ago and I use it everyday. It doesn't take up a lot of space either.
