What's the best way to achieve hypertrophy with pull ups?

For pull-up hypertrophy, use a manageable load for repeated sets in a target rep range, get close to failure with good form, and build enough weekly volume while allowing recovery.

• Practice the target range regularly: For example, if you can do 25 reps and want to improve, try 3 sets of 17, three days per week. This is an endurance example, not a specific hypertrophy prescription. 1
• Choose a load that preserves your target reps: If adding weight makes your repetition count fall below the range you want to train, reduce the load; the training load should stay around or slightly above the target you’re working toward. 2
• Build weekly volume and frequency: A general hypertrophy target is about 15–20 sets per muscle group per week, divided across workouts; the right frequency depends on how well you recover. 3
• Use controlled eccentrics when useful: Starting at the top of a pull-up and lowering under control can help focus on the movement and is described as useful for hypertrophy, though eccentric emphasis can cause more soreness. 4
• Don’t count pull-ups as substantial biceps work: Pull-ups primarily target other muscles; the guest said he generally wouldn’t count biceps during pull-ups, though he would during chin-ups. 5
