TRX Fly for Chest
Set up the TRX suspension trainer at about mid-chest height. Your arms should be extended in front of you and your feet hip-width apart.
Grasp the handles while you are facing away from the anchor point. Walk yourself back so there is tension on the straps, engaging your core.
Lower your body until your chest is near the handles. Keep your elbows with the same angle throughout the set.
Press yourself back up until your arms are extended in front of you but without locking the elbow. Squeeze your chest at the top.
Make sure to keep your body in a straight line throughout the movement. Do not let your hips sag or arch your back.
Breathe out as you press yourself up, breathe in as you lower down.
Go slow and controlled on both the lowering and lifting phases.
For added stability, you can put your feet wider apart in a split stance. You can also add a pause at the bottom to increase time under tension.
