Owner Reviews, Ratings, Comments and Criticism
Assembly is easy - a person needs 2 wrenches 3/4 inch, 1 wrench 11/16 inch, and 1 wrench 1/2 inch to put it together. There's not much to the directions but there's not much to putting it together either - Took 30 minutes for me and that was taking my time. The space required is small - we have a fairly full exercise room and managed to make room in a corner easily due to the small foot print. Very stable doing knee lifts or dips - I weigh 225 and there is no give or flex at all to it - and it never rocks even when working the obliques. For my wife the steps make it easy to mount for the knee raises - I can get in to position standing on my toes, I'm 6 foot 1 inch tall. For dips I need to bend at the knees a little bit to keep my toes off the ground but not much. If a person is looking for a good quality device for these exercises - this is one I am very comfortable recommending.
