The Ice Chamber blog posts some quick tips to help get you over the bar in your next pull-up session; with a little kipping. They are :
- Initiate the pulling action with your lats, not biceps.
- Drive your elbows towards your lats (ideally behind them) to finish.
- Be fast on the rebound. Get your elbows less than 90 degrees asap.
- Bring your center of mass closer to the bar by raising your knees to your chest.
Excellent.
