Blast Fat With Circuit Training
Wide to narrow push-up
Get into modified push-up position with knees down and arms wide, hands in line with shoulders. Lower down, then push back up. Walk hands in so they’re a bit closer than shoulder-width; do another push-up. Alternate for 1 minute.
Stand with feet together. Jump right foot back into a runner's lunge with left knee bent and right leg extended straight behind, reaching heel toward floor; at same time, reach left arm forward and up. Switch legs and arms quickly; continue alternating for 1 minute.
