Half Jumping-Jack

1. Starting Position:
- Stand upright with your feet together and arms resting by your sides.

2. Jumping Movement:
- Slightly bend your knees and prepare to jump.
- As you jump, open your arms out to the sides at shoulder height and simultaneously spread your legs shoulder-width apart.

3. Landing Position:
- Land softly with your feet back together and your arms returning to your sides.
- Ensure your knees are slightly bent to absorb the impact of the landing.

4. Repetitions:
- Repeat the movement for a specified number of repetitions or for a set time, aiming for a rhythmical and controlled motion.

5. Breathing:
- Inhale when you jump out and exhale as you come back to the starting position.

6. Tips for Beginners:
- Start slow to get used to the movement before increasing speed.
- Focus on maintaining good posture with your back straight and core engaged.
- If you have any joint issues, consider doing the movement without jumping (step side to side instead).

7. Cool Down:
- After completing your sets, take a moment to walk around slowly and perform some gentle stretches to relax your body.
