This tone-all-over circuit takes six proven and powerful moves — lunges, planks, pushups, squats, crunches and dead lifts — and amps up their difficulty each week to keep your muscles challenged. Pair these exercises with active rest (keeping your heart rate up during your “rest” time between sets) and you’ll be eager to jump into that bathing suit long before the fireworks start. Do this workout three times a week for a month, along with at least two hours of cardio a week, for the best results.
PERFORM THIS ROUTINE THREE TIMES THROUGH, RESTING BETWEEN SETS FOR A FEW MINUTES. UNLESS OTHERWISE SPECIFIED, DO 12-15 REPS OF EACH EXERCISE, USING A WEIGHT THAT IS CHALLENGING BUT DOABLE FOR A HIGH NUMBER OF REPS. REST TIME IS ACTIVE REST TIME, SO YOU SHOULD BE MOVING CONSTANTLY!
