How to Do Jumping Jacks

Jumping jacks are a full-body, high-intensity cardio workout that anyone can do anywhere. They are a great way to improve your cardiovascular health, burn calories, and tone your muscles.

Instructions:

1. Stand with your feet shoulder-width apart and your arms at your sides.

2. Jump up with your feet spreading shoulder-width apart and swing your arms up overhead.

3. Jump back to the starting position.

4. Repeat steps 2 and 3.

Tips:

* Keep your core engaged and your back straight throughout the movement.

* Land softly on the balls of your feet.

* If you have knee problems, replace jumping jacks with marching in place, running in place, or low-impact jumping (i.e., jump while stepping in and out of cones placed shoulder-width apart as shown in the video).

* Start with fewer repetitions and increase the number of jumps as you get stronger.

Variations:

* To make jumping jacks more challenging, add weights to your hands or wrists.

* Try different variations of jumping jacks, such as side-to-side jumping jacks, front-to-back jumping jacks, or squat jumping jacks.
