The Stamina X plyometric box is a great workout addition. No assembly required, use out of the box. Only need to adjust the various heights you can work with. Very stable platform, wider than most of these items. Item is fairly heavy but that is a plus when considering stability and whether it will hold up. Works for 300+ pound folks and everyone else.
I ordered this item to help modify some of the demanding Insanity burpies. I am very large in ht and wt. This step is sturdy. It does not move when you jump on it and absorbs all the shock from the jump. It is very long which makes for a great base!!!
