Ab Wheel

An ab wheel is a simple device that can help you strengthen your core muscles and improve your posture. Here are some steps to use it effectively:

1. Kneel on a mat and hold the ab wheel with both hands in front of you.
2. Engage your core and roll the wheel forward as far as you can without arching your back or touching the floor with your chest.
3. Pause for a second and then roll the wheel back to the starting position.
4. Repeat for 10 to 15 repetitions or until you feel fatigued.

You can adjust the difficulty of this exercise by using more or less body weight. The more you lean forward, the harder it will be. You can also try different angles or speeds to challenge yourself.
