Snack on This Before Sweating
Putting some fuel in your tank before working out will help you push harder—and as a bonus, burn more calories, says Heidi Skolnik, MS, CDN, FACSM, a nutritionist who's worked with Juilliard School dancers as well as members of the New York Knicks. Use this pre-exercise snack as an opportunity to boost your magnesium levels, as women with deficiencies of this mineral had higher heart rates and required more oxygen to do physical tasks than they did after their levels were restored, found Forrest H. Nielsen, PhD, a research nutritionist with the U.S. Department of Agriculture. (Nielsen adds that we lose magnesium through sweat.) Women should aim to get more than 220 mg of magnesium per day; men, 260. Good sources include almonds and pumpkin seeds (try trail mix with those ingredients an hour or so before your workout) or celery stalks with cashew butter.
