Even on summer’s hottest days, keep cool with the following tips from TOPS Club, Inc. (Take Off Pounds Sensibly), the non-profit weightloss support organization. Go bare (foot, that is). Not only is running around without shoes more playful, it can also keep you cooler. Shuck those shoes, but watch your step. No A/C? No problem. Head off to the mall to get some healthy walking in and do some window shopping to boot.
