It's a sad fact that past the age of about 35, we begin to lose muscle mass. This can be somewhat offset through exercise, although most people still generally tend to get weaker as they get older. A new drug could help, as it's been shown to increase muscle size and strength in elderly mice.

One of the most frustrating things about exercise is how easily progress can be undone, but maybe not all is lost after all. Researchers have now found that muscles keep their nuclei from past growth, which makes it easier to rebuild later after a period of inactivity.

Although exercise is the best way of building muscle, there are cases where people need some help – such people can include those who are frail, or are laid up by injuries. That's where a new prototype device comes in, that uses magnetic fields to "fool" muscles into thinking they're being used.

Bodybuilding, as its name pretty much implies, is all about gettin' big muscles. And while a tape measure can be used to measure the growth of those muscles every now and then, XLFLEX is designed to motivate users by providing them with ongoing real-time measurements AS they're working out.

Georgia Tech researchers have developed a hydrogel that holds muscle stem cells, and by injecting this near the site of a muscle injury they can get to work repairing it. The team says the technique could be effective at treating injuries in the elderly and people with muscular dystrophy.

Why start from scratch when nature has already designed better robot materials and parts than ours? Japanese researchers have now developed a new way to integrate living muscle tissue onto a robotic skeleton, and make it move in a realistic way that takes some of the strain off.

Researchers from the Department of Mechanical Science and Engineering at the University of Illinois have developed an artificial muscle made of carbon fiber and rubber that can lift over 12,000 times its own weight.

New research has revealed that human skeletal muscle has an epigenetic memory determined by earlier growth. This very literal discovery of “muscle memory” potentially has dramatic implications for the long-lasting effects of performance-enhancing muscle building drugs.

In 2015, a Duke University team made a world-first breakthrough, growing functioning human muscle tissue in a lab using cells from muscle biopsies called myogenic precursors. Now the research has leapt forward with working muscle being successfully grown from scratch using pluripotent stem cells.

What initially started out as a MIT research project has now become the Humon Hex, a fitness wearable that can measure how an athlete’s muscles are using oxygen in real time.
