If you are one of those people that dread stepping onto the treadmill or don’t have an hour to spare to burn a sufficient amount of calories, don’t worry! There are plenty of quick treadmill workouts that will leave you energized and dripping in sweat. 

1. Interval Training

Interval training is a great way to make a quick treadmill session worthwhile. Running for 10 minutes, then walking at a speed of 4.2 mph at an incline of 15% for 10 minutes, and then repeating works wonders. It makes the time go by faster, works every muscle and burns an intense amount of calories. Check out this awesome Yahoo! Sports article to see why interval training is amazing. While running, you will look forward to walking at the 15% incline and vice versa, which will make time fly by!

4. HIIT

The blogger behind “Blonde Ponytail” reveals her post-baby workout, swearing by a quick 20-minute workout. She keeps her workouts short and simple, but that doesn't mean you won't be dripping in sweat by the end of it:

5. Treadmill Tabata 

Treadmill tabata, according to SheKnows.com, is a killer 20-minute workout. It incorporates running, jump roping, squatting, push ups and planks, with short rests in between. According to the blog, taking a moment to breathe is very important, even if it is only for 10 seconds. Check out the workout here. 

6. Agility Training

You don’t have to limit yourself to simply running on the treadmill. Incorporate some of your favorite strength moves for some agility training to get the most out of your 20-minutes. Lunge on the treadmill’s lowest speed, do high knees or butt kicks while you jog in place, or run backwards to get a great hamstring workout!

7. Arm Workouts

Grab a pair of dumbbells and get working on those arms while walking on the treadmill. You can do a chest press, tricep exercise, and shoulder press while getting your cardio fix. 

As you can see, you don't have to torture yourself on the treadmill for an hour. Try one of these fun and quick workouts next time you hit the gym, and scorch calories in half the time!
