Stand with your heels under the sling trainer and grip the handles with both hands. Keep your legs straight. Your body and legs should form as straight a line as possible, keeping your hips raised. From this position, bend your arms and pull your upper body towards the handles in a controlled manner. As you do so, pull your shoulder blades back and down. Then slowly straighten your arms again and lower your body in a controlled manner.
Attention:
Keep your body as straight as possible throughout the entire movement; do not let your hips drop or push them upwards; actively stabilise your shoulder blades; do not raise your shoulders; move your elbows backwards in a controlled manner; Keep your head in line with your spine; do not use momentum or hip movement; distribute the load as evenly as possible between both arms; guide the sling trainer in a controlled and even manner.
Lighten:
Sit more upright – lean your body less far back (shorter swings); bend your knees more; reduce the range of motion (bend your arms less).
Harden:
Adopt a more hanging position – lean your body further back (longer sling); add extra weight.
