TRX is fun and challenging suspension training appropriate for all levels. Designed by a navy seal, this type of training improves neuromuscular efficiency, which results in better balance and coordination. It strengthens prime movers as well as core musculature and improves flexibility. This is the best addition to traditional functional training. Most of TRX exercises are total body and activate many muscles resulting in higher caloric expenditure per minute, making it highly effective for people working on changing their body composition.
