My favorite post-workout snack is water-packed, canned sardines on low-sodium Triscuits, topped with Louisiana hot sauce, says Geoff Bagshaw, group fitness manager for EQUINOX Fitness Clubs in Florida. "[Sardines] contain lots of heart-healthy omega-3’s and are also loaded with calcium, along with having a full array of B vitamins, iron, magnesium, phosphorus, potassium, zinc, copper, and manganese," Bagshaw says. "The crackers provide dietary fiber and the hot sauce contains capsaicin, which some studies indicate may help to increase your metabolic rate, along with other benefits."
