This product is very good and rugged. Quality of this product is superb as well. The added bonus of a workout chart and workout CD's are also helpful with a personal workout routine. Recommend to all when comparing it to a TRX system.
It's a great product that I have seen made in several variations over the years. I met a fellow military veteran in Oklahoma in a Marriott hotel gym that first introduced me to this kind of suspended gravity training and his homemade version was even a better construction.
This Weider version is good quality for the price don't get me wrong. If they could change one part it would be the straps that go over a doorway. The two straps together are too thick for tight tolerance doors. The straps are also very long for short doors and don't quite shorten enough.
If each strap had its own separate loop it would be more versatile to use over any door as well as any rod or bar. Hence the 4 instead of 5 stars.
