Hamstrings can become tight during and after exercise, and this is an important muscle group which is integral to movements such as bending the knees, walking up and down stairs, running and extending the hip. Located in the backs of the thighs, they can become painful and sore if you don’t stretch the hamstring muscles adequately in warm-up routines and recovery after training. One of the easiest solutions is to use a foam roller to soften the connective tissue around the muscles, flushing away lactic acid and reducing the chances of DOMS (Delayed Onset Muscle Soreness). Want to know how to foam roll your hamstrings? Just watch our handy video guide. You’ll see how easy it is to use a vibrating foam roller to effectively massage both legs at the same time, sitting on the roller for maximum pressure. Use your arms for support by placing them on the exercise mat behind you. Watch the Pulseroll in action now. Also find this post on our Google+ profile.
