In-Place Step

1. Start by standing upright with your feet shoulder-width apart and arms at your sides.

2. Lift your right knee up as if you're marching on the spot, making sure to lift it as high as comfortable. At the same time, you can pump your left arm forward for balance and increased cardio effect if desired.

3. Lower your right foot back to the ground and repeat the action with your left knee and right arm.

4. Continue alternating legs and arms in a marching motion.

5. Maintain an upright posture throughout the exercise, keeping your head up and your core engaged.

6. Start with a moderate pace and increase or decrease the intensity based on your fitness level.

7. Continue stepping on the spot for your desired duration or number of steps.

8. Keep your moves smooth and steady, focusing on the movement of your legs and arms.

9. Breathe evenly throughout the exercise, inhaling and exhaling fully.

This exercise can be incorporated into a warm-up routine or performed as a low-impact cardio workout on its own. It's an effective way to elevate your heart rate and increase lower body muscular endurance.
