Yes, inverted rows are an excellent progression for improving pull ups. The inverted row is a challenging body weight exercise that strengthens multiple muscle groups in the upper body. An overhand grip slightly wider than shoulder width closely mimics the movement pattern used in pull ups. Once you can efficiently perform around four sets of 10-15 reps of the inverted row, experiment with variations like the feet elevated inverted row to increase the difficulty. Eventually, you should be ready to pull your entire body weight by performing assisted or unassisted pull ups.
