Touchdown jacks are a type of jumping jack exercise that combines cardio and strength training. They are a great way to improve your cardiovascular health, build muscle, and burn calories.
To do a touchdown jack, start by standing with your feet shoulder-width apart and your arms at your sides. Then, jump up and reach your arms overhead while simultaneously extending your legs out to the sides. As you land, lower your arms and bring your legs back together. Repeat this movement for 10-12 repetitions.
