The Ultimate Guide To Maintaining Muscle (Even When You Can't Workout)
Ben Greenfield Fitness
Muscle is not for bodybuilders anymore. Instead muscle (not the big, bulky stuff, but the tight, toned lean stuff) is now heavily correlated with everything from anti-aging to cognitive performance to metabolism and beyond. So it's pretty darn important, even if you have no desire to strut in a Speedo on muscle beach. But have you ever wondered how fast you lose muscle when you stop working out? How about how muscle you can expect to lose when you age? The best way to maintain muscle? From cutting-edge NASA research on maintaining maximum muscle as you age to the surprising nutrients that have been proven by science to keep muscle on your body as long as possible, you're about to discover all these answers and much more in today's podcast. My guest in today's episode, Alex James Ritson, is currently finalizing a Master's degree in Sport and Exercise Nutrition at Middlesex University in London, is co-owner of Lean Body Performance, an online nutrition and training coaching company and is very well-versed in a particular area of interest that he has: how protein intake affects lean muscle preservation. During our discussion, you'll discover: -What exactly happens to your muscle when you are "bed-bound" or unable to exercise...   -How fast you lose muscle and how fast you lose strength when you quit working out (you'll be surprised!)...   -The actual cellular mechanisms behind muscle loss...   -Exactly how much muscle you lose as you age, and the latest research that shows how you can slow down that muscle-loss process...   -Specific activities that have been shown maintain muscle that don't involve lifting weights...   -The top specific supplements or nutrients that stave off muscle loss when you can't exercise...   -The fascinating lessons we can learn from astronauts and space research when it comes to maintenance of muscle....   -How to strike a balance between anti-aging, longevity and protein restriction and not losing too much muscle...   -And much more!
