How to do the TRX Deltoid Y-Fly
Attach a suspension trainer to a secure anchor point above head height.
Grip the handles of the suspension trainer and step back until your body is at a desired angle to the ground, arms straight with palms facing each other in a neutral grip.
Stabilize your core and keep your body in a straight line from head to heels – you will be in a prone incline position with your feet on the ground.
Maintaining this body position, bring your arms up and out into a "Y" shape by retracting your shoulder blades and raising your arms slightly above shoulder level.
Ensure that the movement is controlled and that you're not just relying on the momentum; the focus should be on the muscles doing the work.
Slowly lower your arms back to the starting position.
Perform for a set number of repetitions and sets, resting as needed between sets.
It is important to maintain proper posture and movement control throughout the exercise to prevent injury and ensure the target muscles are effectively engaged. The angle of your body will determine the difficulty of the exercise; the closer you are to horizontal, the more challenging it will be.
