Yes, some people are non responders to exercise while some are “super” responders. A recent study looked at 1000 people put on the same exercise program. The results, which I discuss in this vid, may shock you!
This is a very interesting area of research. We all know people who do the same exercise as we do, yet either don’t seem to benefit much, or benefit far more than we might expect. Having trained hundreds at this point and or communicated with many thousands more, I have seen that first hand.
