Jumping jacks target your quadriceps, hamstrings, glutes and hip flexors. They also work your shoulder muscles as well as your chest and abdominal muscles. In short, jumping jacks provide an effective cardio workout with additional benefits for strengthening key muscle groups.

In general, it is recommended to do a minimum of 30 minutes of moderate-intensity cardio three times a week for overall health benefits.

You could always opt for modified versions instead such as half-jumping jack sit-outs where you only partially raise your arms overhead or lateral jumps that require less height but still allow you to get some cardio in from the same tiny space.

When performing this exercise you want to make sure that when you're hopping outwards each time jump out far enough that your feet end up wider than shoulder length apart (typically about 2-3 feet). You also want to make sure that upon taking off both legs should come off the ground simultaneously without having any kind of lag between them.

No special equipment is needed when doing jumping jacks except maybe some comfortable clothes and supportive workout shoes if desired – everything else happens through sheer bodyweight alone.
