Some days, you can't wait to get to the gym and power through that workout, and other days, it's hard to convince yourself that an energy-busting workout is exactly what you need. But, as they say, the hardest part is showing up — so once you do, why not add a few calorie-burning minutes to your workout?

Just five extra minutes of exercise can really make a difference, up to 50 extra calories [1] burned during your workout. Those extra 50 calories may not seem like much, but if you're sticking to a five-a-week gym routine, that's an extra 250 calories a week! Every little bit helps when you're trying to lose weight, so print [2] or pin this poster to motivate you to stick it out just a little bit more before you end your workout.
