Power snatches are one way to help overcome a slump in biceps training.

Q: Do Olympic-lifting exercises have any value to a bodybuilder in increasing arm size?

A: Yes, strange as that may sound. In fact, I’ve found that power snatches are one way to help overcome a slump in biceps training.

There are two reasons for that: First, lowering the bar from doing power snatches or power cleans provides a rapid eccentric stretch for the elbow flexors. It recruits them in a manner they are not accustomed to and helps break a plateau. Second, power snatches help develop better thoracic and cervical alignment, which provides better neural drive for the elbow flexors.

Where is the research on it? Nowhere. Just years of strength coaching and living in the now, paying attention to athletes’ training journals and eventually looking at progression curves with the strength-training software I developed.
