Exercise has been shown to lengthen lifespan by as much as five years. A small new study suggests that moderate-intensity exercise may slow down the aging of cells. As humans get older and their cells divide over and over again, their telomeres—the protective caps on the end of chromosomes—get shorter. To see how exercise affects telomeres, researchers took a muscle biopsy and blood samples from 10 healthy people before and after a 45-minute ride on a stationary bicycle. They found that exercise increased levels of a molecule that protects telomeres, ultimately slowing how quickly they shorten over time. Exercise, then, appears to slow aging at the cellular level.
Ah, arm fat. You know what it is. And let’s be honest. We all know we shouldn’t make a big deal of such things (all body types are beautiful, after all). But there is still a moment’s hesitation we all face when it comes to donning a cute spaghetti top or sleeveless dress. If there’s one word to describe arm fat, it would have to be stubborn. And no matter how much you control your diet or cut back on dessert, arm fat still seems to stay. Irritating, right? But before figuring out a way to reduce flabby arms muscles, it’s important to know what leads to the accumulation of arm fat.
Back to the tricep pushups and really activating those tricep muscles for toned arms. If you need a rest, that's totally cool. Just take a break in the up position and maintain that plank form. This way you are still working your arm muscles just by holding your body weight up. So that's totally fine for some of our beginners out there. For those who are more advanced, we want you going as hard as you can and trying to hit that 15 to 20 reps. You're doing great.
