Start with this dynamic warmup: 30 high knees, 30 mountain climbers, 25 jumping jacks, 10 inch worms. Once you're loosened up, move on to the circuits ahead. Do three sets of 15 reps of each exercise (unless otherwise noted), with a 45-second rest between moves. Complete one circuit in full before tackling the next. When you're finished, cool down with this head-to-toe stretch sequence.
