The quad muscles are located at the front of the thighs and have in important role in movement of the legs, including the bending and straightening of the knees. They work alongside other muscle groups such as the hamstrings in many activities such as squatting, running, walking and cycling, so may undergo stress when exercising or training. If you want to enhance performance, reduce DOMS (delayed onset muscle soreness) and prevent the muscles from becoming too tight, using a vibrating foam roller is the ideal solution. The rolling action can target trigger points with the vibrations helping to achieve a deeper massage. As portable products, foam rollers are perfect for use in injury rehab clinics, the gym, home or anywhere else you want to use them. In our expert video guide, we show you how to use a foam roller effectively on one leg, placing the roller under the quads while providing stability using the arms and other leg.
