MIT scientists find that motor neuron growth increased significantly over 5 days in response to biochemical (left) and mechanical (right) signals related to exercise. The green ball represents cluster ...

Muscle growth is more than just moving heavy weights—it's a complex biological response. In this video, we explain how resistance training creates micro-tears in your muscle fibers, triggering a ...

Why some of us have sculpted, toned and visible muscles and some of us carry a little more flab depends on a lot of factors. Part of it is how and how much you work out, explains Todd Schroeder, ...

Exercise can have benefits at the level of neurons, through chemical and mechanical effects, researchers find. The discovery could inform exercise-related therapies for repairing damaged and ...

I’ve always been bookish. I spend most of my time in the lab rather than running, jumping or climbing. But I still have super strong muscles. They’re way bigger than when I was a young. I asked my ...

Here’s something we don’t talk about enough: aging doesn’t shrink all your muscles evenly. Just like getting stronger isn’t a one-size-fits-all deal, neither is getting older. A recent review by ...

Our muscles get stronger when put under stress and now robots could do the same, thanks to a soft gel that becomes harder when exposed to vibration. Zhao Wang at the University of Chicago and his ...

When you train your muscles (either by lifting weights, running, or doing resistance work), you create tiny microtears in your muscle fibers. While this might sound detrimental, it’s actually a good ...
