Stand with your feet placed shoulder width apart and arms extend straight to your sides, raised at shoulder height. Now, do 50 small circles with your hands by rotating them in the forward direction. Then switch to 50 small backward circles. The backward and forward arm movement tones all the muscles of the arms including the triceps, biceps, shoulders and back muscles as well.
Scientists don’t know exactly why exercise changes the structure and function of the brain, but it’s an area of active research. So far, they’ve found that exercise improves blood flow to the brain, feeding the growth of new blood vessels and even new brain cells, thanks to the protein BDNF (brain-derived neurotrophic factor). BDNF triggers the growth of new neurons and helps repair and protect brain cells from degeneration. It may also help people focus, according to recent research.
FIT TIP: If you exercised on an empty or almost-empty stomach, you're probably feeling light-headed or even nauseated or headachy. Your immediate food fix: A high-carb nosh, like a banana or half a bagel, will refuel you and kick-start your recovery. And don't forget to drink plenty of water with your snack. Intense or long workouts can leave you dehydrated.
Whether we’re fully conscious of it or not, we’re always looking for how to be happy. And exercise is one of the most obvious steps to take, as it’s not a coincidence that you feel better after a good workout: It’s science. A Penn State University study found that people who exercised, whether it was a mild, moderate or vigorous workout, had more pleasant feelings than those who didn’t. (1)
