biceps femoris
The biceps femoris is the lateral hamstring on the back of the thigh, with long and short heads forming a thick band from hip to knee. It flexes the knee, extends the hip, and rotates the leg outward, vital for running, jumping, and deadlifts. Key for posterior chain power and injury prevention.
Thigh
semimembranosus
The semimembranosus is a posterior thigh hamstring forming the teardrop at knee back, flexing knee and extending hip. Powers deadlifts, lunges, and deceleration in sports. Prevents ACL strains by stabilizing.
Thigh
semitendinosus
Semitendinosus is the slender medial hamstring with a long tendon, flexing knee and extending hip. Aids in medial knee stability for cutting sports. Complements semimembranosus for balanced posterior chain.
Hip
gluteus maximus
Largest hip muscle, gluteus maximus extends and externally rotates thigh for powerful hip thrust in squats, deadlifts, running. King of posterior chain.
