When you're not raring to go but in need of a quality cardio session, let this treadmill workout come to the rescue. Once you complete an extended walking hill warmup that makes your booty burn, our 45-minute plan gradually intensifies with a few challenging
belly-fat-blasting intervals sprinkled into the mix. Don't worry — when the time comes to get running, you'll take off with ease and enthusiasm! Once this workout is completed, you'll leave the gym feeling energized and accomplished with over three miles under your belt.
