As a fitness expert with a background in physical therapy, I can tell you that the toe touch exercise is a classic stretching movement designed to improve flexibility, particularly in the lower back and hamstrings. Here's how you can perform it properly:

1. Stand straight with your feet together.
2. Slowly bend forward from your waist, keeping your legs straight.
3. Reach down towards your toes with both hands. You can start by reaching for your shins and gradually work your way down to your toes as your flexibility improves.
4. Keep your head neutral and avoid rounding your back. It's normal for your back to round slightly, but try to maintain a straight posture as much as possible.
5. Hold the stretch for 15 to 30 seconds, breathing deeply and relaxing into the stretch.
6. Slowly return to the starting position.

Remember, it's not about how far you can reach but the quality of the stretch. Never force the stretch or bounce, as this can lead to injury.
