TRX/ POWER PLATE 101Have you been working out at the community center for a couple of years and need to change things up, try our TRX Workout System and Power Plate Machine. The TRX System was developed by a former Navy Seal and the Power Plate Machine uses acceleration training that utilizes vibration technology. Both systems are great for strength training and developing flexibility. Personal Trainer: Jeremiah Salazar. Ages 18 & Older.
