Nutritional secret to building muscle in your 40s and beyond

Increasing protein intake with your training regime will help retain muscle strength

We see it all the time. The busiest place in the gym is the mirror next to the weights - plenty of flexing, a few selfies and a protein shake thrown in for good measure.

Don't worry, I'm not about to tell you that you need to go down that route - although you do need to start paying attention to your muscles. In a sense, your muscles are the forgotten man of mainstream health coverage: the media tends to obsess over body fat, looking lean, and reducing overall weight. However, our muscles are key to keeping us moving freely throughout our busy lives. We neglect them at our peril.
