1. Sprinting

If you want to feel the maximum amount of burn and torch the most calories in the least amount of time, look no further than the anaerobic king — the sprint. Each sprint should be run at least 90 percent of your running capacity. In other words: Fast! HOW TO DO IT: Start by standing with one foot in front of the other. Explode out of your start by powerfully driving your knee up as your opposite arm pumps. What your arms do, your legs do, so remember to powerfully pump those arms. Also remember to properly warm up as sprints incorporate your largest muscle groups at maximum power output. REPS/SETS: Five sets. Beginners: 60 to 80 meters. Intermediates: 100 to 120 meters. Advanced: 200 meters. Sprints should include proper rest to be able to perform at maximum capacity.

2. Burpees

Burpees are easily the most efficient way to burn calories and hit every major muscle group. And while some might view them as a punishment, try looking at them as your one-way ticket to a hot bod. HOW TO DO IT: Start standing with your feet underneath your hips and hands at your side. Bend your knees and place your hands on the ground. Kick your feet back into a push-up position, and then lower your chest to the ground. Push your chest off the ground into a cobra position while keeping your legs on the ground. Explosively snap your hips up so that your feet come to your hands. As you stand, drive your arms up to the sky as you jump and clap your hands overhead. REPS/SETS: Every minute on the minute, do eight to 10 burpees for 10 minutes.

3. Squat Jumps

Yes, squats help you sculpt your best booty. But jump squats burn mega calories too. HOW TO DO IT: Start standing with your feet hip-width apart. With a flat back and tight core, lower your glutes back and down into a squat. With power, drive your arms up as you squeeze your glutes and explode up into the air. Land softly and lower back down and repeat. REPS/SETS: Five sets of 10.
