This exercise is great for the posterior chain or back of the body.
It works pretty much everything especially- hamstrings, lower back, core, rhomboids, latissimus dorsi, trapezius, pectoralis, and deltoid.
Cues:
Shoulders and hips should be square( parallel to the ground ).
Naval drawn in towards spine.
Spine should be nuetral( lordotic lumbar, kyphotic thoracic, lordotic cervical). It helps if you keep your eyes on the ground.
Try not to shrug shoulders when rowing, but pinch shoulder blades down and back.
Try to keep the stabilizing arm’s elbow slightly bent.
Try not to lower the knee as you contract hamstrings.
Increase progression by increasing weight, or trying different angles of shoulder abduction.
