Similar Assertions

Taking a specific supplement called HMB-FA before a tough workout might help slightly reduce muscle damage in guys who regularly lift weights, but the evidence isn’t strong enough to say for sure it works.

If guys who lift weights train too much — like a whole lot in a week — their bodies might get stressed in a way that could hurt their performance, and scientists can see this stress through certain markers in their body.
