Getting some isolation hamstring curls in leg session No1 of the week!

Most people think hamstrings only serve one function: knee flexion. In reality, the hamstrings are not one single muscle, but a group of muscles with multiple functions. The hammies' most important function is hip extension, which is vital for explosiveness, sprinting, jumping, and even low-back health!
