Burn, Baby, Burn

High intensity interval training (HIIT) is trending. The workout craze blends cardio-strength training movements with short periods of rest for a high-cal burn that maxes reward in minimal time. The after-burn kicks the body’s repair cycle into overdrive, so you keep burning for up to 24 hours post-workout, meaning a healthier heart, increased metabolism and fat loss—oh, and a bangin’ bod that’s too legit to quit.
