5. Wind Markers: Mark a starting line on the round, then mark four points out in front of that line, each approximately 10 yards apart, for a total of 40 yards (an approximation is fine). Start in a sprinting position at the starting line. Sprint out as fast as you can to the first marker, then turn and sprint back to start. Repeat this out and back pattern to each line. After you’ve returned from the fourth line, perform 4 burpees, then 4 push-ups. That’s 1 round. Complete 7 rounds as fast as possible.
Set up a box behind you and then lower your body until your glutes touch it. Touching the box requires you to “sit back” as you squat, as if you were lowering yourself into a chair, and this action gets the glutes and hamstrings maximally involved in the lift. It also helps you to perfect your squat form. You can start with a higher box and gradually move to smaller boxes as you improve, ultimately training your body to squat below parallel with no box at all. Better still, the box squat places no strain on the knees, so even people with knee problems can attempt it safely.
Build more muscle: Cardio gets all the glory for melting fat, but it’s actually far more important to focus on building muscle. It’s pretty simple: Lipolysis happens in the mitochondria of the muscles, so the more muscle you have, the more mitochondria, and the more potential to burn. Plus, the more muscle mass you carry, the more your BMR is burning calories at rest. Strength training is also one of the strongest ways to spark production of testosterone and growth hormone, which both help to break down fat, Seedman adds.
