I've been using the Lifeline Jungle XT suspension straps for a week now, along with a few of my customers. I can honestly say that they live up to their claim of a full body workout, and it can be a very short workout for those of you with busy schedules. The quality of the straps/buckles is very good and made with commercial use in mind, AND made in the US! The only downfall is that their shipping can be quite slow, with 1-3 days simply to process the order and then add shipping.
AS a former Physical Education teacher, I'm always skeptical about items like this with their big claims... but these truly work! I've even in fact, added them to the inventory at the shop.
