Looking to burn extra calories during your workout without adding on extra time? No problem! Just follow these five easy tips to start seeing more results in less time.

Green Tea 3X a Day.
A study from the University of Geneva in Switzerland found that in addition to caffeine, green tea contains the plant product catechin polyphenols, plant chemicals that may boost your metabolism.

Interval Training.
Doing the same exercise routine at the same intensity level every day makes your body “bored” and causes the dreaded workout plateau. Throw a curveball into your routine with interval training, which involves varying the intensity of your workout throughout your exercise session.

1. Every five minutes into your walk, jog for one minute.
2. Every five minutes into your bike ride, shift into a higher gear and pedal hard for a minute.
3. If you swim, turn on the speed every other lap.

You'll burn more calories in the same amount of time.

Eat.
Cutting too many calories can backfire in more ways than one. Try to subsist on morsels and your metabolism will slow so much that you’ll not only stop losing weight, but you’ll be lucky if you can peel yourself off the couch.

Drink H2O!
Put five rubber bands around your wrist every morning. That’s how many 16-ounce bottles of water you should drink during the day to rev your metabolism, helping burn more calories. When you drink one bottle, take off a rubber band to signify how many bottles you have left to drink. German researchers found when they had 14 participants drink about 17 ounces of water, the volunteers’ metabolic rate -- or how quickly they burned calories -- jumped a third within 10 minutes of drinking the water and remained high for another 30 or 40 minutes. The researchers estimated that over a year, increasing your water consumption by 1.5 liters a day (about 50 ounces) would burn an extra 17,400 calories or about five pounds worth. Since much of the increased metabolic rate is due to the body’s efforts to heat the water, make sure the water you’re drinking is icy.

Fresh Air.
Maybe it’s the fresh air, maybe it’s the sunshine, but something about exercising outside in the open makes you walk or run faster than doing the same exercise in the gym.
