When a contractor has to pursue resistant a freight set on it, it adapts to the hassle by creating new muscle fibers and devising neurologic changes that at last brand it stronger, says Ben Hurley, PhD, a strength-training researcher at the University of Maryland. And spell weights are accessible roughness tools, they're not the lone effective ones.
