TRX Mpact classes will push you to new levels of strength using the TRX Suspension Trainer, Functional Training Tools, and your own bodyweight. While Mpact classes emphasize the development of quality functional strength and lean muscle mass, you will still get a healthy dose of heart-pumping conditioning drills to reset your system and give you an extra challenge in each session. Needless to say, TRX Mpact will leave you quivering, in a good way, long after your workout is complete.
