Leg anatomy and function
The legs encompass the largest muscle groups in the human body. The primary ones are: quadriceps, hamstrings, glutes, and calves. The proper development of these muscles is essential not only for aesthetics but for metabolic health, functional strength, and injury prevention.
The quadriceps is composed of four muscles: rectus femoris, vastus lateralis, vastus medialis, and vastus intermedius. The rectus femoris originates from the hip (biarticular) while the vasti originate from the femur. The primary function is knee extension. The vastus medialis (VMO) is critical for patellar stability. The rectus femoris also contributes to hip flexion and is fully stretched in exercises like deep squats and low-foot leg press.
The hamstrings (biceps femoris, semitendinosus, and semimembranosus) run along the back of the thigh. They are biarticular muscles that flex the knee and extend the hip. The biceps femoris has two heads: the long head (originates from the ischium) and the short head (originates from the femur). These muscles are often weaker than the quadriceps in athletes, increasing the risk of strains. A hamstring-to-quad ratio (H:Q) of at least 0.60-0.70 is considered protective.
The glutes include the gluteus maximus (the most voluminous muscle in the body), gluteus medius, and gluteus minimus. The gluteus maximus is the primary hip extensor and contributes to external rotation. The medius and minimus abduct the hip and stabilize the pelvis during walking and unilateral movements. Squats and deadlifts activate the entire posterior chain, but hip thrusts and glute bridges better isolate the glutes.
The adductors (adductor magnus, longus, brevis, gracilis, pectineus) are an often-ignored group covering the inner thigh. The adductor magnus also has a 'hamstring-like' component at its posterior insertion. Developing the adductors improves hip stability and prevents groin injuries. They are trained with deep squats (where they reach maximum stretch), sumo deadlifts, and Copenhagen planks.

How to train legs effectively
Weekly volume for legs varies by group: quadriceps 12-20 sets, hamstrings 10-16 sets, glutes 12-20 sets. The legs are the largest muscle group and require more recovery time. For most athletes, 2 weekly leg sessions (e.g., Monday and Thursday) allow adequate volume and optimal recovery.
Quad-dominance vs posterior chain
Many athletes have a quad-dominant imbalance with relatively weak hamstrings and glutes. To correct this, dedicate at least one hip-dominant extension exercise per session (Romanian deadlift, hip thrust, good morning). The Romanian deadlift is the best exercise for hamstrings in the lengthened position, with solid evidence for preventing posterior thigh muscle injuries.
Key exercises
Barbell squat (back or front): the king of leg exercises. Leg press: accessory quad volume with less back stress. Romanian deadlift: fundamental for hamstrings and glutes. Barbell hip thrust: the best glute exercise in terms of EMG activation. Leg curl (prone or seated): isolation for the biceps femoris. Bulgarian split squat: excellent for quads and glutes unilaterally.
Rep ranges
Quadriceps contain a high proportion of type I fibers and respond well to higher reps (12-20). Hamstrings have a more mixed composition and respond to 8-15 reps. Squats and leg press are effective with 5-20 reps. Leg curls work best at 10-15 reps with particular attention to the eccentric phase (slow lowering).
