If you want a better workout, try a little caffeine before you lace up your tennis shoes.
If you're a trained athlete, caffeine may help you burn more calories a few hours post workout.
Research also finds that drinking coffee may also improve circulation - getting our blood flowing a little more. And a better circulation may mean a better workout.
Another study finds that caffeine improves memory.
People who had about 8 ounces of coffee did better than test given a day later. This brain boost may help with recall for your exercise routine.
According to the Journal of Applied Physiology, endurance athletes combining caffeine with carbs after a workout may increase the stockpile of muscle fuel meaning more reserves for the next workout.
BUT DON'T OVERDO IT. A 16 OUNCE CUP OF COFFEE OR 400 MILLIGRAMS IS ALL YOU NEED A DAY.
But don't cut water out of your liquids. It is still important to drink plenty of water to hydrate yourself while you work out.
