🦿 Leg Workouts

Leg Anatomy and Training Principles

The legs contain the largest and most powerful muscles in the human body. Training legs properly requires understanding the different muscle groups and targeting them with appropriate exercises.

Major Leg Muscle Groups

1. Quadriceps (Front of Thigh)

• Four muscles: Rectus femoris, vastus lateralis, vastus medialis, vastus intermedius
• Primary function: Knee extension (straightening leg)
• Best exercises: Squats, leg press, leg extensions, lunges
• Largest muscles in front of thigh

2. Hamstrings (Back of Thigh)

• Three muscles: Biceps femoris, semitendinosus, semimembranosus
• Primary functions: Knee flexion (bending leg) and hip extension
• Best exercises: Romanian deadlifts, leg curls, good mornings
• Often underdeveloped relative to quads

3. Glutes (Buttocks)

• Three muscles: Gluteus maximus, medius, minimus
• Primary function: Hip extension, abduction, and rotation
• Best exercises: Hip thrusts, deadlifts, squats, lunges
• Largest muscle in entire body (gluteus maximus)

4. Adductors (Inner Thigh)

• Multiple muscles that bring legs together
• Function: Hip adduction and stabilization
• Trained during squats, lunges, and adductor machine

5. Calves

• Gastrocnemius (larger, two-headed muscle)
• Soleus (underneath gastrocnemius)
• Function: Plantarflexion (pointing toes)
• Best exercises: Standing calf raises, seated calf raises

Best Leg Exercises

Quad-Dominant Exercises

1. Back Squat

• The king of leg exercises for overall development
• Targets quads, glutes, adductors, hamstrings, core
• Bar on upper back, descend until thighs parallel or deeper
• Allows heaviest loading of any leg exercise
• Sets/Reps: 3-5 sets × 5-8 reps (strength) or 8-12 reps (hypertrophy)

2. Front Squat

• Bar rests on front of shoulders
• More quad-focused than back squat
• Easier on lower back, requires upright torso
• Excellent for quad development and core strength
• Sets/Reps: 3-4 sets × 6-10 reps

3. Leg Press

• Seated machine pressing variation
• Allows very heavy loads without lower back strain
• Foot placement alters emphasis (high = glutes/hams, low = quads)
• Great for high-volume work and drop sets
• Sets/Reps: 3-4 sets × 10-15 reps

4. Bulgarian Split Squat

• Rear foot elevated on bench, front leg does work
• Unilateral (single leg) exercise
• Incredible quad and glute activation
• Fixes strength imbalances between legs
• Sets/Reps: 3 sets × 10-15 reps per leg

5. Leg Extension

• Isolation exercise for quadriceps only
• Seated machine, extend knees against resistance
• Excellent for pre-exhaust or finishing sets
• Use controlled tempo, squeeze at top
• Sets/Reps: 3 sets × 12-20 reps

6. Walking Lunges

• Dynamic single-leg movement
• Targets quads, glutes, balance, coordination
• Can use dumbbells or barbell for resistance
• Great for athleticism and functional strength
• Sets/Reps: 3 sets × 12-16 steps per leg

Hamstring & Glute Exercises

7. Romanian Deadlift (RDL)

• Best hamstring and glute builder
• Hip hinge movement, minimal knee bend
• Lower bar to mid-shin with straight legs
• Incredible hamstring stretch at bottom
• Sets/Reps: 3-4 sets × 8-12 reps

8. Hip Thrust

• Most effective glute isolation exercise
• Upper back on bench, barbell across hips
• Thrust hips up to full extension, squeeze glutes
• Can load very heavy for strength
• Sets/Reps: 3-4 sets × 8-15 reps

9. Leg Curl (Lying or Seated)

• Hamstring isolation exercise
• Curl heels toward glutes against resistance
• Both lying and seated variations effective
• Excellent for building hamstring thickness
• Sets/Reps: 3-4 sets × 10-15 reps

10. Nordic Curl

• Advanced bodyweight hamstring exercise
• Kneel with ankles anchored, lower body forward
• Eccentric-focused (lowering phase)
• Extremely challenging but highly effective
• Sets/Reps: 3 sets × 5-10 reps (or negatives)

11. Good Morning

• Barbell on upper back, hip hinge forward
• Targets hamstrings, glutes, and erectors
• Teaches proper hip hinge pattern
• Use moderate weight with controlled tempo
• Sets/Reps: 3 sets × 8-12 reps

Calf Exercises

12. Standing Calf Raise

• Emphasizes gastrocnemius (larger calf muscle)
• Stand on platform, raise up onto toes
• Full stretch at bottom, full contraction at top
• Can use machine or hold dumbbells
• Sets/Reps: 4 sets × 15-20 reps

13. Seated Calf Raise

• Emphasizes soleus (deeper calf muscle)
• Seated position with knees bent ~90 degrees
• Complements standing calf raises
• Use controlled tempo with pause at top
• Sets/Reps: 4 sets × 15-20 reps

Complete Leg Workout Programs

Leg Training Techniques

1. Pause Squats

Pause 2-3 seconds at bottom of squat before standing.

• Eliminates bounce reflex, builds strength from bottom
• Improves squat technique and depth
• Use 70-80% of normal squat weight

2. Drop Sets

After reaching failure, reduce weight 20-30% and continue.

• Particularly effective on leg press and leg extensions
• Creates extreme metabolic stress and pump
• Use on last set only to avoid excessive fatigue

3. High-Bar vs. Low-Bar Squat

Bar position changes muscle emphasis.

• High-bar: Bar on upper traps, more upright, quad-dominant
• Low-bar: Bar on rear delts, more forward lean, glute/posterior chain dominant
• Neither is "better"—choose based on goals and comfort

4. Tempo Training

Control descent phase for 3-5 seconds.

• Example: 4-second lower, 1-second pause, explosive up
• Increases time under tension dramatically
• Use lighter weight (60-70% of normal)

5. 1.5 Reps

Go down, up halfway, down again, then all the way up = 1 rep.

• Brutal for quads on leg press or squats
• Keeps tension on muscles longer
• Use moderate weight, expect extreme burn

Squat Depth and Form

Squat Depth Standards

• Quarter squat: Barely bending knees (insufficient for growth)
• Half squat: Thighs ~45 degrees (better but still incomplete)
• Parallel: Hip crease level with top of knee (minimum for full development)
• Below parallel: Hip crease below knee (optimal for most people)
• Ass-to-grass: Full depth squat (if mobility allows safely)

Proper Squat Form

1. Setup: Bar on upper back (high-bar) or rear delts (low-bar)
2. Stance: Feet shoulder-width or slightly wider, toes slightly out
3. Brace: Deep breath, brace core like preparing for punch
4. Descent: Push hips back, bend knees, keep chest up
5. Depth: Descend to at least parallel (hip crease at knee level)
6. Ascent: Drive through heels, push floor away, squeeze glutes
7. Knees: Track over toes, don't cave inward

Common Squat Mistakes

• Knees caving inward: Weak glute medius, increases injury risk
• Forward knee travel limited: Not letting knees go past toes (unnecessary restriction)
• Excessive forward lean: Indicates weak quads or poor ankle mobility
• Heels lifting: Poor ankle mobility or weight too far forward

Common Leg Training Mistakes

1. Skipping Leg Day

• Legs are largest muscle group, critical for overall development
• Solution: Train legs minimum 1x per week, ideally 2x

2. Only Training Quads, Neglecting Hamstrings

• Creates muscle imbalance, increases knee injury risk
• Solution: Match quad volume with hamstring volume

3. Squatting With Poor Depth

• Quarter squats provide minimal benefit
• Solution: Squat to at least parallel (hip crease at knee)

4. Using Too Much Weight at Expense of Form

• Ego lifting leads to injury and poor muscle development
• Solution: Use weight you can control through full range

5. Neglecting Calves

• Calves need direct training to grow
• Solution: 8-16 sets of calf work weekly

6. Not Training Unilaterally

• Always doing bilateral (two-leg) exercises masks imbalances
• Solution: Include Bulgarian split squats, lunges, single-leg press
