Half to Full Jumping-Jack

1. Start by standing straight with your feet together and arms at your sides.

2. Jump your feet out to just wider than hip distance apart while raising your arms to shoulder height sideways to create a 'T' shape with your body.

3. Quickly bring your feet back together while lowering your arms to your sides. This is the 'Half Jumping Jack.'

4. Immediately jump your feet out wider (more than hip distance) and simultaneously raise your arms straight above your head, touching your hands together if possible. This is the 'Full Jumping Jack.'

5. Reverse the motion by jumping your feet back together and bringing your arms back down to your sides.

6. Repeat this sequence of half to full jumping jacks in a smooth and continuous manner for the desired number of repetitions or time duration.

7. Remember to maintain an upright posture and breathe regularly throughout the exercise, exhaling during the jumping movement.

Tips: Make sure to land softly on the balls of your feet to reduce impact on your joints. Keep a slight bend in your knees during the landing to help absorb shock. Scale the exercise by adjusting the jumping intensity or by stepping out to the sides instead of jumping for a lower impact version.
