Chin-ups are one of the most challenging body-weight exercises and one that many clients love to hate. While some clients can bang them out with no problem, others struggle to do even one. Others harbor no illusion that they’ll ever be able to do one, so they don’t even bother trying. Not surprisingly, chin-ups also happen to be an exercise that many exercise enthusiasts wish they could do, but wishing doesn’t give one the strength to lift his or her own body weight. The only way to do chin-ups is to start practicing.
