When you only have 20 minutes for a treadmill cardio workout you need to stick with the top fat burning strategies to burn maximum fat in minimum time. The 3 awesome tips below from barrys bootcamp will help you get the most out of your short cardio workouts on a treadmill or with bodyweight exercises. These are great tips for people who are too busy for long cardio workouts.

Cardio Bootcamp Workout Tip #1: Raise The Roof
Jump on a treadmill and warm-up at a moderate pace then start jogging or running at a faster pace. When you feel ready raise your arms up in the air and keep them there for 30-60 seconds. Recover for 1-2 minutes then go again. This throws off your balance and causes your body to burn more fat and calories. It also raises your heart rate even more and provides a great ab and arm workout, it also teaches your body to resist fatigue, and it's totally fun.

Cardio Bootcamp Workout Tip #2: Run or Walk Backwards
Whether you are working on a treadmill or walking or running outdoors running backwards is a killer leg and butt workout. It also improves balance and coordination. On top of all this running backwards keeps it interesting, boosts variety, and is not easy so your body automatically burns more calories and fat. Try going forward for 3 minutes then go backwards 3 minutes and just keep alternating like this. Want to make it even more challenging? Combine raise the roof with backwards running for even more intensity and fun!

Cardio Bootcamp Workout Tip #3: Use Your Body vs. Machines
If you need a break from machine cardio or you don't have access to cardio machines you can get a high intensity fat burning cardio workout using just your bodyweight. The key is combining the best bootcamp exercises into non-stop circuits and staying high energy the entire time. Try 30-60 seconds of each of the following; step runners, running up and down stairs, mountain climbers, burpees, jumping jacks, jump squats, jumping lunges, and just keep going for 20 minutes or check out the video here for more ideas.
