• Boosts energy and brainpower. College requires a fair amount of energy and lots of brainpower to keep up with classes and other activities. Exercise delivers oxygen and nutrients to the brain and various tissues. This means you can concentrate better and think clearly. Plus, because exercise helps your lungs and heart, you have more energy to do other things.


This is a particularly cool one. Neuroscientists used to believe the brain was the only organ incapable of growing new cells—which partly makes sense, since we need our brains to be relatively stable over time, to keep our memories intact and to keep us us. But in recent years, it’s become clear that the brain, too, can grow new neurons, in a process called neurogenesis. And what seems to spur the growth of new neurons, perhaps above other activities, is aerobic exercise. (Other things, like meditation and antidepressant medication, have also been shown to trigger brain new cell growth.) The area of the brain that seems most capable of growing new cells is the hippocampus, the seat of learning and memory. It's also the area that’s known to “shrink” in depression, and particularly in dementia—so the fact that we may have some control over its health is exciting.
Really work on burning that fat by going as hard as you possibly can. None of these workouts are going to be as effective as they can be if you're not going at your maximum intensity. Don't worry about the person near you. Don't compare yourself to other people. Just go as hard as you possibly can and have fun doing the thing, ladies and gentlemen. Keep on killing it.

Drink at least eight glasses of water in between meals to control your appetite. This will support metabolism and burn fat. Do not drink too much water with your meals as it can dilute the stomach acids and impair digestion. Drinking pure spring water detoxifies your system and balances your stress hormones. Sodas, coffee, and sugary drinks should be avoided.
The skin also serves as a release point for heat. (See “Why Does My Face Turn Red When I Exercise?” for more on that.) When you exercise, your muscles generate a lot of heat, which you have to give up to the environment so your body temperature doesn’t get too high, Hackney says. The heat in the muscle transfers to the blood, which shuttles it to the skin; it can then escape into the atmosphere.
