2. TRX Y Fly
TRX straps at Mid Length
Extend your arms overhead in a "Y" position—palms forward, tension on TRX, offset feet. Lower your body down, keep your arms extended, and maintain a plank. Pull on the handles, drive your knuckles back, and lift your chest while keeping your eyes on the anchor point.
Common Faults: Breaking at the hips; bending elbows
Frankel says: “Here, your arms go up over your head, allowing you to maintain a rigid spine so that you’re getting that core work as you reach up overhead. TRX forces your to establish stability in your core and legs to get your arms to move as opposed to resting on a ball or bench. It gives you a big bang for your buck: more muscles are working and integrated into the movement, and everything becomes a core exercise.”
