It’s happened to the best of us: We gear up, cue up a killer cycling routine, and head straight for the gym— only to find out it’s temporarily closed (curse you, maintenance!). With heavy hearts and glutes dying to feel the burn, we sullenly make our way back home. At this point, you may be tempted to give up for the remainder of the day, but don’t change out of your gym clothes just yet! You already have the only workout machine you need on you.
Most gymgoers who are struggling with flabby arms either spend hours on the treadmill or work their biceps day in, day out. What you should focus on are the triceps because this muscle makes up two-thirds of your arm. Train it once or twice per week to lose arm fat and build upper-body strength. Your arms might get bigger, but they'll look leaner and more defined.
Exercise has long been correlated with a longer life, but it’s only recently started to become clear why this might be. Studies, like a new one in the journal Preventive Medicine which found that exercise is linked to longer caps at the ends of chromosomes, have helped flesh this out a bit more. These caps, called telomeres, naturally shorten as we age, with each cell division. People who live a long time have telomeres that are in better shape than those who don’t—but there’s a lot we can do to affect the rate at which they shorten over the years. The team behind the new study looked at data from CDC's National Health and Nutrition Examination Survey, and found that for people who exercised regularly, their telomeres were 140 base pairs longer on average than sedentary people's. Which correlates to being years “younger” than their sedentary peers.
