The muscle-up is a rare beast – an upper-body exercise that requires both pulling and pushing power and phenomenal core strength to boot.

We can always count on Christian to give us some great new movements that, in addition to spurring new muscle growth, will elicit bewildered stares from all the ACE certified trainers in the gym.
