It’s a myth that you have to spend hours doing intensive training if you want to get fit; those hour-long and longer workout sessions are for those who’re involved in professional sports or too obsessed with exercise. For the rest of us, it’s enough to spend as little as 10 minutes, three times a day spaced at random intervals, doing squats, lunges, stretches, or any other workout you can get done with little or no equipment. The other option is interval training – work out for just 15 or 20 minutes, but make every minute count. Instead of exercising at the same pace the entire time, sprint for 30 seconds, walk for next one minute. Repeat this cycle for as long as you can, and watch your weight go down and your endurance go up. It works with any kind of cardio exercise where you can vary the pace.
