Re: Pullup grip
Very often, you won't know when your grip will fail until right before it does.
If you are working on a slick bar, this can happen unexpectantly. Our HB at gym is bare because of the pvc strap system that slides over it that is used to lock in gymnasts to the bar when swinging giants around the bar or other circle work. This rubs any chalk off the bar and polishes it which makes for a very slippery bar.
Some of our boys have peeled off unexpectantly when their form was good for unknown reasons. Other guys have peeled because of poor form which is to be expected when in concert with a slippery bar.
No amount of chalk, honey, etc will solve this.
With some bars at CF, they have just the same problem.
