If you find it hard to lose weight with your busy schedule, the news keeps getting better. First, just 20 minutes of exercise was proven to help increase your metabolism. Now, a study has found that working out intensely for just 2.5 minutes can spur calorie burn throughout the day — an extra 200 calories' worth.
In the latest study, five healthy men performed sprint interval training on a stationary bicycle (five 30-second intense intervals with four minutes of easy cycling in between). Although the men were sedentary the rest of the day, they ended up burning 200 more calories during the days they did the short bout of exercise than the days they didn't exercise at all.
Even though this was a small study, the encouraging results are reason enough to add intense intervals into your workout routine. It's also good news for those of you who can never seem to fit a full workout into your day. Read on for ideas on intense exercises you can do anywhere for 2.5 minutes so you too can reap the afterburn benefits.
Perform these at maximum intensity; you can break them into 30-second or one-minute intervals to make it more manageable.

Don't stop at just 2.5 minutes, though. Besides upping your total calorie burn, longer exercise helps you stay healthy and prevent disease. Aim for at least 150 minutes a week; here are five ways to make sure you hit that number.
