Muscles Targeted:

1. This exercise primarily targets the back and secondarily targets the biceps.

2. Using an underhand grip during most back exercises allows for better bicep engagement.

Form:

1. Start by sitting upright, holding onto the attachment with an underhand grip, keeping the chest up and shoulder blades back.

2. Using your elbows as your guide, pull them towards your hips and squeeze your back.

3. Return to your starting position without letting the chest cave and keep each rep constant throughout the entire set.

Rep Ranges:

1. This exercise is best performed in moderate to high rep ranges.

2. Adding too much weight may lower your range of motion or force you to use momentum, taking the emphasis away from your back.
