A: We used to be skeptical too, but we always notice that as we begin getting in shape and start flexing more as we check our progress (whether it’s in front of a camera or our bathroom mirrors), our muscularity increases quickly.

We thought it was just a coincidence, and that our training and diet were primarily responsible for our accelerated gains—and we were probably right for the most part. But a study we’ve discussed before suggests that flexing a muscle for extended periods does indeed help make your muscles larger and more detailed… [Read more…]
