Gym Strategies 5

Do intervals

Minute per minute, high-intensity intervals—periods of all-out effort interspersed with short, low-intensity “breaks”—come with more cardiovascular and fat-loss benefits than any other workout, says Wall. For instance, in one study from Human Performance Laboratory at the University of Wisconsin-La Crosse, people who performed a 20-minute interval workout with exercises including pushups, burpees, squats and lunges burned an average of 15 calories per minute—nearly twice as many as during long runs. To burn similar calories, follow the workout’s protocol: Perform as many reps as possible for 20 seconds, rest for 10 seconds and repeat for a total of four minutes. Rest one minute, then repeat for a total of four rounds.
