How to do the TRX Internal Rotation
Attach the suspension trainer to an overhead anchor point and grab the handles with both hands. Your palms should be facing down.
Lean back with straight arms to assume the starting position; your body should be at an angle to the floor, supported by the suspension trainer. Keep your feet shoulder-width apart and body in a straight line from head to heels.
Keeping your body stable and core engaged, bend your elbows and start rotating them inward towards your torso while pulling the suspension trainer handles towards you.
Rotate as far as is comfortable while keeping your elbows fixed at your sides.
Pause briefly at the peak of the internal rotation before slowly returning to the starting position with arms extended and hands at shoulder height.
Perform the designated number of repetitions, ensuring that the movement is controlled throughout.
Remember to:
Keep your core tight and engaged to prevent your body from swaying during the exercise.
Perform the internal rotation movement in a controlled manner without letting the suspension trainer control the pace.
Adjust the difficulty of the exercise by changing your body's angle relative to the floor – the more horizontal you are, the more intense the exercise will be.
Breathe out during the internal rotation and in during the return to the starting position.
