The benefits of interval training

To help you find the calorie-burning workout that fits your lifestyle and goals, we rounded up the best exercises for weight loss here. If you're working out in intervals, do the exercise for 30 seconds every minute and rest for the remaining 30 seconds. As you progress, you can increase your time to 45 seconds of activity and 15 seconds of rest. Remember, you want to be working at your maximum—leaving you out of breath by the end of that interval.
