I was trying to come up with a clever Brittney Spears inspired headline like “Wanna strong pull up body? Better jump, b*tch!” but I’ll keep this professional (ish). Here’s the bottom line, if you want to safely and effectively build upper body strength to do solid bodyweight pull ups, try these “jumping” or “eccentric” pull ups where you start from the top and slowly lower yourself down. Note, if you’ve never done these before you will likely be very sore the next day.
