1. Do one set of strengh-training moves.
Recently revised guidelines from the American College of Sports Medicine (ACSM) recommend a single set of 8 to 12 strength reps (with enough weight that you can’t do any more) instead of 2 or 3 sets.
2. Mix it up.
Try adding bursts of speed to your cardio routine to save time while burning the same number of calories (or maybe even a little more) and building your speed and endurance.
3. Build a pyramid
A pyramid approach to your cardio workout will save time over exerting the same effort throughout, says Keli Roberts, an ACSM-certified personal trainer and group-fitness manager at Equinox Pasadena. Here’s how it works: You gradually move from low intensity for a longer time to high intensity for a shorter time, then back down again. For example, run for 5 minutes at 4 mph, then 3 minutes at 5 mph, 1 minute at 6 mph, 3 more minutes at 5 mph, then finally 5 more minutes at your original speed (4 mph); repeat.
