The question, then: How do you make that enough? And what should you do differently when the number of sessions goes up? “That’s going to vary a lot person to person, depending on what your goals are,” says Jayson Lee, a personal trainer in New York City. “If your goal is to lose weight, the focus is going to be more on cardio because it burns slightly more calories in a shorter period of time. But if general strength and overall fitness is what you’re after, you’re better off focusing on resistance moves that build muscle mass.” It’s easier to get moderate cardio into your day-to-day without the gym, Lee points out: You can take the stairs at work, bike instead of drive to do errands, walk the dog, and so on. So during you’re dedicated workout minutes, it’s better to make sure you’re covering bases, like lifting, that you aren’t able to do outside of the gym (or your garage). Take a look at what to do, when—whether you have two, three, or five days a week to work out.
