• Suspension training allows you to deliberately change your center of gravity, which challenges your muscles. 
• TRX work builds strength by combining functional movements with dynamic positions. The exercises challenge your core, back, shoulders, chest, hips and leg – a true total body workout. 
• TRX exercises help you with other functional exercises, like running, swimming, golf swings, etc.

TRX work is integrated and engages intensive, interconnected movements that require coordination. It enhances the body’s strength and stabilization. It also decreases your risk of injury.
