Small Group Training provides focused attention for safety and success under the eye of a Certified Personal Trainer. The TRX Suspension Trainer is the original bodyweight-based training tool that builds strength, balance, flexibility, and core stability. Because every body movement is powered by the torso—the abs and back working together to support the spine during everyday activities—Suspension Training works to build that needed core strength. All our exercises create an element of instability that calls on your core to provide balance and coordination.
