What is the single best leg exercise?

The barbell back squat. It trains all four leg muscle groups — quadriceps, hamstrings, glutes, and calves — in a single compound movement. Squats allow the heaviest loading of any leg exercise, making them ideal for progressive overload. Muscle activation studies show high recruitment across the entire lower body. If you could only do one leg exercise, the squat would build more total leg muscle than any other movement.

How many leg exercises do I need per workout?

Three to five exercises per leg workout is sufficient for most lifters. A well-structured leg day includes: one squat pattern (back squat, front squat, or leg press), one hip hinge (Romanian deadlift or stiff-leg deadlift), one single-leg movement (Bulgarian split squat or lunge), and one or two isolation exercises (leg curl, leg extension, or calf raise). More exercises beyond this provide diminishing returns and unnecessary fatigue.

Should I train quads and hamstrings on the same day?

Yes. Training quads and hamstrings together in one session is the most practical approach for most lifters. They are functionally related — compound movements like squats and leg presses work both — and training them together allows 2-3 full days of recovery before the next leg session. Splitting quads and hamstrings across different days typically results in less total weekly volume and recovery complications.

How often should I train legs per week?

Train legs 2 times per week for optimal muscle growth. Each session should include 4-6 exercises with 12-16 total working sets. This frequency provides enough stimulus for growth while allowing adequate recovery — legs recover slower than smaller muscle groups. Advanced lifters may benefit from 3 sessions per week with reduced volume per session, but 2 sessions works for the majority.

Why are my legs not growing?

The most common reasons legs do not grow: (1) Not training close enough to failure — legs require intense effort because they handle heavy daily use, (2) Insufficient volume — most lifters need 14-20 sets per week across quads, hamstrings, and glutes, (3) Poor exercise selection — too many machines, not enough compound movements, (4) Not prioritizing legs — training them tired at the end of workouts. Fix these issues and leg growth follows.

Best Leg Exercises Ranked (2026)

Legs are not one muscle — they are four: quadriceps (front thigh), hamstrings (back thigh), glutes (hips), and calves (lower leg). A complete leg workout must address all four. The problem is most lifters do the opposite — they hammer quads with leg presses and extensions while neglecting hamstrings and glutes entirely.

This ranking prioritizes exercises with high overall leg activation, meaning movements that train multiple leg muscles at once, plus essential isolation work for lagging muscle groups. Each exercise links to its full guide. Browse all leg movements in our quadriceps, hamstrings, glutes, and calves exercise libraries.

How We Ranked These Exercises

We evaluated leg exercises on four criteria:

Muscle activation: Studies measuring quadriceps, hamstring, glute, and calf recruitment across movements.
Overload potential: Can you add significant weight over time? Squats and leg presses rank high; bodyweight lunges rank lower despite being excellent exercises.
Practicality: Available in most gyms, reasonable injury risk, works for multiple experience levels, does not require excessive setup.
Which muscle group it targets: Quad-dominant exercises are common in most programs. Hamstring and glute exercises rank higher because they fill gaps that typical leg days miss.

The 14 Best Leg Exercises

Barbell Back Squat

The king of leg exercises. The barbell back squat trains quads, hamstrings, glutes, calves, and core in a single compound movement. It has the highest loading potential of any leg exercise — strong squatters move 400+ lbs. No other exercise builds as much total leg mass. High bar targets quads more; low bar shifts emphasis to the back of your legs (hamstrings and glutes).

Primary muscles: Quadriceps, glutes. Secondary: Hamstrings, calves, core. Best for: Overall leg development, strength, athletic performance.

Romanian Deadlift (RDL)

The best hamstring exercise that exists. The Romanian deadlift trains the hamstrings under a deep stretch with heavy loads — the exact stimulus that builds muscle. It also hits the glutes hard through hip extension. Unlike leg curls, the RDL trains the hamstrings in their hip extension function, not just knee flexion. Every leg program needs this movement.

Primary muscles: Hamstrings, glutes. Secondary: Lower back, core. Best for: Hamstring development, backside strength.

Full Romanian deadlift guide

Bulgarian Split Squat

The ultimate single-leg exercise. Bulgarian split squats train one leg at a time with the rear foot elevated, forcing single-leg stability while still allowing heavy loading. They fix imbalances, build quad and glute strength, and hammer hip flexor mobility. Many coaches argue they are as effective as two-leg squats for muscle growth with less spinal load.

Primary muscles: Quadriceps, glutes. Secondary: Hamstrings, hip flexors. Best for: Correcting imbalances, single-leg strength, quad development.

Leg Press

A machine compound movement with massive loading potential. The leg press removes the balance requirement of squats, letting you focus purely on leg drive. Foot placement changes emphasis: high and wide for glutes/hamstrings, low and narrow for quads. It is excellent for accumulating volume after heavy squats without taxing the lower back.

Primary muscles: Quadriceps, glutes. Secondary: Hamstrings. Best for: Quad growth, training to failure safely, post-squat volume.

Full leg press guide

Goblet Squat

The best squat variation for beginners and a legitimate muscle-building exercise for all levels. Holding the weight in front forces an upright torso, teaching proper squat mechanics while hitting quads hard. The goblet squat is also excellent for high-rep finisher sets and home workouts with a single dumbbell or kettlebell.

Primary muscles: Quadriceps, glutes. Secondary: Core, upper back (isometric). Best for: Beginners, squat technique, high-rep sets, home training.

Barbell Hip Thrust

The highest glute activation of any exercise in muscle activation studies. The hip thrust isolates the glutes through full hip extension with heavy loads and minimal hamstring involvement. Unlike squats and deadlifts, the resistance curve peaks at lockout — exactly where the glutes are strongest. If glute development is a priority, hip thrusts are non-negotiable.

Primary muscles: Glutes. Secondary: Hamstrings, core. Best for: Maximum glute development, glute strength, aesthetic goals.

Full hip thrust guide

Hack Squat

A machine squat with fixed back support that isolates the quadriceps. The hack squat removes the stabilization demands of free-weight squats, letting you focus entirely on quad contraction. The angled sled path hits different portions of the quads than vertical movements. Excellent for accumulating quad volume with reduced injury risk.

Primary muscles: Quadriceps. Secondary: Glutes. Best for: Quad isolation, training to failure, lifters with back issues.

Full hack squat guide

Lying Leg Curl

Direct hamstring isolation through knee flexion. The lying leg curl trains the portion of hamstring function that RDLs miss — bending the knee. The hamstrings cross both the hip and knee joints, so complete development requires both hip extension (RDLs) and knee flexion (leg curls) movements. The lying position allows the best stretch at the start.

Primary muscles: Hamstrings. Secondary: None significant. Best for: Hamstring isolation, knee flexion strength, injury prevention.

Full lying leg curl guide

Walking Lunge

A dynamic single-leg movement that trains the entire lower body through a natural gait pattern. Walking lunges build single-leg strength, stability, and coordination while hitting quads and glutes hard. The continuous stepping creates a metabolic challenge that static lunges do not provide. Use dumbbells, a barbell, or bodyweight.

Primary muscles: Quadriceps, glutes. Secondary: Hamstrings, calves, core. Best for: Functional strength, athletic performance, conditioning.

Full walking lunge guide

Leg Extension

Pure quadriceps isolation. The leg extension is the only exercise that completely isolates the quads without any glute or hamstring involvement. It is excellent for pre-fatiguing quads before squats, as a finisher after compounds, or for targeting the teardrop (vastus medialis). Use moderate weight and controlled reps — this is not a power exercise.

Primary muscles: Quadriceps. Secondary: None. Best for: Quad isolation, pre-exhaust, targeting VMO, rehab.

Full leg extension guide

Seated Leg Curl

A leg curl variation with the hips flexed, which places more stretch on the hamstrings in the starting position. Some research suggests seated leg curls produce slightly higher hamstring activation than lying curls due to the stretched position. Both are valuable — use lying curls and seated curls in your rotation for complete hamstring development.

Primary muscles: Hamstrings. Secondary: None significant. Best for: Hamstring stretch under load, variation from lying curls.

Full seated leg curl guide

Front Squat

A barbell squat variation with the bar racked on the front shoulders. Front squats force a more upright torso position, shifting emphasis to the quadriceps and upper back. They are more technically demanding than back squats and use less absolute weight, but they build quad strength without the forward lean that taxes the lower back. Essential for Olympic lifters.

Primary muscles: Quadriceps. Secondary: Glutes, upper back, core. Best for: Quad emphasis, upright squat mechanics, Olympic lifting.

Full front squat guide

Sumo Deadlift

A wide-stance deadlift variation that shifts emphasis to the quads, glutes, and adductors compared to conventional pulling. The sumo stance reduces range of motion and places the torso more upright, making it easier on the lower back. It is a legitimate main lift — many powerlifters pull more weight sumo than conventional.

Primary muscles: Glutes, quadriceps, adductors. Secondary: Hamstrings, back, core. Best for: Lifters with long torsos, glute/quad emphasis, powerlifting.

Full sumo deadlift guide

Standing Calf Raise

The primary calf builder. The standing position keeps the knee extended, which maximizes gastrocnemius (upper calf) activation. Calves are notoriously stubborn — they handle your bodyweight all day — so they require heavy loads, high rep ranges (15-25), and high frequency (3-4x per week) to grow. Pause at the bottom for a full stretch.

Primary muscles: Gastrocnemius, soleus. Secondary: None significant. Best for: Calf development, lower leg strength, ankle stability.

Best Leg Exercises by Muscle Group

Quadriceps

Top 3: Barbell back squat, hack squat, leg extension. Squats provide the heavy compound stimulus, hack squats add volume with reduced spinal load, and leg extensions isolate the quads directly.

Hamstrings

Top 3: Romanian deadlift, lying leg curl, seated leg curl. The RDL trains hamstrings through hip extension; leg curls train them through knee flexion. You need both patterns for complete hamstring development.

Glutes

Top 3: Hip thrust, Bulgarian split squat, sumo deadlift. Hip thrusts isolate the glutes with peak tension at lockout. Split squats and sumo pulls hit glutes hard through compound movement patterns.

Calves

Top 2: Standing calf raise (gastrocnemius emphasis), seated calf raise (soleus emphasis). Both are necessary. Train calves 3-4 times per week with high reps and full range of motion.

How to Build a Leg Workout From This List

You do not need all 14 exercises. Here is how to structure a complete leg day:

Pick 1 squat pattern: Back squat OR front squat OR leg press (3-4 sets of 6-10 reps)
Pick 1 hip hinge: Romanian deadlift OR sumo deadlift (3-4 sets of 8-12 reps)
Pick 1 single-leg movement: Bulgarian split squat OR walking lunge (3 sets of 8-12 reps per leg)
Pick 1 hamstring isolation: Lying leg curl OR seated leg curl (3 sets of 10-15 reps)
Add calf work: Standing calf raise (4 sets of 15-20 reps)

Total: 4-5 exercises, 16-19 sets per leg workout. Optional add-ons: leg extension for extra quad volume, hip thrust for extra glute volume. For detailed volume guidelines, see our sets per muscle group per week guide.

The Most Common Leg Training Mistake

Skipping hamstrings and glutes in favor of more quad work

Most gym leg days look like this: squats, leg press, leg extension, maybe some half-hearted leg curls at the end. This creates quad-dominant legs with underdeveloped hamstrings and glutes — a recipe for imbalanced development and increased injury risk.

The hamstrings and glutes are as important as the quads for both aesthetics and performance. A leg that is only developed from the front looks flat from the side. Weak hamstrings relative to quads increase ACL injury risk.

The fix: Match your quad and hamstring/glute volume. If you do 12 sets for quads, do 10-12 sets for hamstrings and glutes combined. Always include at least one RDL variation and one leg curl variation per leg day.
