Many celebrities have leaped and even shared their videos on social media. And although it usually involves jumping up and down from the box — regardless of size — it can be a good cardio workout.

If you're looking for a 15-second fat burn and a powerful sweat session, take inspiration from Jennifer Garner, who is doing crazy sports stunts at 50. The actor last seen in the film 'Project Adam' traveled with his trainer Beth Nisley. The two perform an intense sequence of jumping into a box that looks creatively choreographed but tightens the legs and lungs. Dressed in stretchy sweatpants, a t-shirt, and his hair in a ponytail, Garner performed a coordinated leg routine with his trainer. The two jumped up and down from the crate and struck gracefully and relentlessly.

Landing on both feet at first, they jump on one leg, switch with the other, and twist and turn sideways. It's just perfection that can only be achieved through practice.

If you're new to boxing and want to choreograph in this order, it's a good idea to start slowly. It's essential to do some stretching before boxing and depending on how good you are; you can increase the height of the box. For starters, you can choose a song to play in the background and then move your feet to the beat, both at first, then take turns. It's a great cardio workout that you can complete in style, and just 15 seconds — with a 30-second rest and one repetition — can be great for heart and lung health.
