You can create a killer fat burning boxing workout by combining some basics like jump rope intervals, bodyweight exercises and medicine ball moves. Just stick to the format below and you'll be blasting fat the fun way just like Hilary Swank did when she was preparing for her movie Million Dollar Baby.

Start With A Dynamic Boxing Warm-up
Alternate between 20 minutes of jump rope and 10 seconds of rest for 2-4 minutes. If you're not good with a rope just pretend like you have one and do the jumps without the rope. Continue with a 2 minutes dynamic warm-up circuit that includes toe touches, arm circles, torso rotations, and jumping jacks.

Include Basic Bodyweight Exercises
Alternate between squats, pushups, bodyweight rows (you can sub dumbbell rows if you don't have a pullup bar). If you're strong enough you can add weight after every set. Try 15-20 reps of each exercise or 30-45 seconds of each exercise. Combine them in a circuit to increase endurance and try 3-4 circuits.

Mix Medicine Ball Moves with Boxing Exercises
Try 30 seconds of pushups with one hand on medicine ball then repeat on the other side. Take a break then repeat 1-2 more times. Continue with 45-60 seconds of side to side shuffles pressing a medicine ball forward every time your feet come together. Repeat 1-2 more times. Finish up with 30 seconds of medicine ball sit up to plank (ball between hands or hands on ball). Repeat 1 more time.

Finish Up With Classic Boxing Exercises
Alternate between 30 seconds of quick jabs, 30 seconds of upper cuts, 30 seconds of speed punches. Rest for 60 seconds then repeat two more times. The entire workout should only take about 20 minutes but can burn up to 400 calories if you workout with intensity.
