Alt grip pull ups
Alternate grip pull ups use one overhand and one underhand grip, providing a different challenge to a standard pull up while helping develop pulling strength and grip.
I recommend performing this exercise in an even number of sets, and switch grip each time (ie set 1: left hand overhand grip and right hand underhand grip, set 2: leg hand underhand grip and right hand overhand grip).
There’s a short video demonstrating this exercise on this page. For more resources to help your calisthenics journey, check out courses here.
