Training boards tip 9: One arm pull-up

Now you really have some power! Follow the same guidelines as for pullups, but rotate your body inward to center your weight under your arm you’re using. If you’re getting close but can’t quite make it up, do an offset pull up, but perform the negative (lower yourself) as a pure one. The potential for injury is very high, so absolutely critical to be smooth. Don’t bounce!
