Adequate hamstring mobility has a direct effect on your cycling performance. The quadriceps and hamstrings are antagonistic muscles: when the one fires the other shuts off. Think of kicking a ball. As the leg is swinging toward the limit of its range of motion, the hamstrings fire, shutting off the quadriceps to ensure that your leg doesn’t go beyond its range. A limited range of motion means a shorter, weaker kick. A similar scenario plays out on the bike. When your hamstrings lack range of motion, they turn on during the pedal stroke, shutting off the quadriceps and hindering the power you can produce.
