Hamstrings

The hamstring is a group of muscles on the back of your thigh. It is responsible for bending or flexing your knee, while the quadriceps straightens it. Hamstrings and glut muscles are crucial for explosive acceleration. Having strong and flexible hams results in a longer running stride and also lessens the effects of fatigue that affect your form over time. The hamstring is the most frequently strained muscles in soccer.
