An ab wheel is a fitness device used to strengthen the abdominal muscles. It consists of two handles connected to a wheel that rolls on the ground. To use an ab wheel, kneel on the ground with your hands on the handles and your feet shoulder-width apart. Roll the wheel forward until your body is in a straight line from your head to your heels, then roll it back to the starting position. Repeat for multiple repetitions.
The ab wheel is an effective way to work the abdominal muscles, as it requires both concentric and eccentric contractions. The concentric contraction occurs when you roll the wheel forward, and the eccentric contraction occurs when you roll it back. This type of training is beneficial for building muscle strength and endurance.
