484: Sets to Failure with Low Weights – Do You Recruit/Exhaust More Muscle?

So now that we have more research that tells us lifting lighter weights can still be good for muscle size gains assuming we accumulate enough volume it’s always good to test some of the theories behind why the light training may have benefit. Some would say maybe it is because taking a light set all the way to fatigue may recruit all possible muscle fibers – slow twitch for a while and then finally fast twtitch until the muscle is completely exhausted – but is this just a theory or is there actually sound data to support it – let’s check out this new study on the area.
