Wanted to do box jumps and step ups/lunges with weights in small space (NYC apartment), this box is great for that. I am over 200 pounds, box is very stable for all kinds of movements, with or without weights. Changing the height is very easy and relatively fast. I also have a Stamina pull-up and dip tower, which is also a great product. You really can't go wrong with their functional fitness products.
I love this thing, its a 4in1 plyo box that allows an athlete to save space and money! I put a full product review on my blog, just click here to read it! http://stuchstrength.com/gym-equipment-reviews/staminax-adjustable-height-plyo-box-review/
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!!!
