The split squat hold is a great exercise for building strength in the legs and improving balance and stability. Here are the steps to perform a split squat hold :

1. Stand with your feet shoulder-width apart and take a step forward with one foot, placing it about two to three feet in front of the other foot.

2. Keep your back straight and your core engaged as you lower your body down by bending your knees. Your front knee should be directly above your ankle, and your back knee should be hovering just above the ground.

3. Hold this position for a designated amount of time, while keeping your body stable and your balance centered over your front foot.

4. Slowly rise back up to the starting position by straightening your front leg and stepping back to the starting position.

5. Repeat the exercise with the other leg.
