You can also do aerobic and strength, “This type of circuit alternates 1-2 sets of resistance exercise (body weight, free weights, dumbbells, kettle bells, bands, etc.), with brief bouts of cardiovascular exercise (jogging in place, stationary cycling, rowing, etc.) lasting anywhere from 30 seconds to 3 minutes.” You can do the exercises anywhere, and many of them require little to no equipment, which is great if you’re a busy mom who has little to no time to hit the gym.
