How to Get Bigger Legs: Quads, Hamstrings, Glutes and Calves

The short answer

How to get bigger legs: squat or press for the quads, hinge and curl for the hamstrings, add direct glute and calf work, and run 10 to 20 hard sets per muscle group per week. Squatting alone covers the quads and glutes reasonably and the hamstrings and calves barely at all, which is why most people's legs grow unevenly.

Legs also respond to the position you load them in more clearly than any other body part, and two of the cleanest studies on that were done on the hamstrings and the quads.

Four muscle groups, not one

"Legs" is four separate training problems:

• Quadriceps, on the front of the thigh, straighten the knee. Trained by squats, presses and extensions.
• Hamstrings, on the back, bend the knee and extend the hip. Trained by curls and hinges, and they need both.
• Glutes, the hip extensors, do most of the work in squats, hinges and thrusts.
• Calves, which raise the heel, and get almost nothing from anything else you do.

A program built only from squats and leg presses trains the first and third of those well and leaves the other two behind. That is the single most common reason legs stall.

Hamstrings: the exercise position matters more than the exercise

This is the most useful finding in leg training and it takes one sentence to apply.

Twenty participants trained one leg on a seated leg curl and the other on a prone leg curl, at 70% of one-rep max, ten reps, five sets, twice a week for twelve weeks. The seated curl, where the hip is flexed and the hamstrings are therefore already lengthened before the knee even moves, produced greater whole-hamstring growth: +14% against +9% (Maeo et al., Medicine and Science in Sports and Exercise, 2021).

So if your gym has both machines, use the seated one. Then add a hinge, because the leg curl and the Romanian deadlift load the hamstrings in different ways and the hamstrings do two jobs.

Quads: where in the range you train changes where you grow

Forty-five untrained women did eight weeks of knee extensions in one of four ranges of motion: full, the initial (stretched) portion only, the final (contracted) portion only, or alternating between the two. Cross-sectional area was measured at four points along the femur.

The group training the initial, lengthened portion gained more than every other group at the point furthest up the thigh, and more than the final-range, full-range and control groups at two other points. The group training only the contracted portion was, at two of the four measurement points, no better than not training at all (Pedrosa et al., European Journal of Sport Science, 2022).

Do not read that as "do partial reps". Read it as: the stretched half of the rep is doing the work, so do not cut it short. Squat to a depth you can control, let your knees travel forward, and take leg extensions from a fully bent knee rather than a half-rep at the top.

The exercise list

Every exercise below exists in GymEvo's library, with the equipment options shown in brackets.

Quads

Hamstrings and glutes

Calves

Calves need a full stretch at the bottom and a pause. Bouncing through the range with heavy weight is the reason most people believe their calves do not respond.

Sets, reps and rest

• Weekly sets: 10 to 20 per muscle group, and count them separately. A squat session is quad and glute volume, not hamstring volume. The training volume calculator keeps the count honest.
• Reps: 5 to 8 on heavy squats and deadlifts, 8 to 15 on presses, split squats and curls, 10 to 20 on calves.
• Effort: 2 to 3 reps in reserve on squats and deadlifts, closer to failure on machines. A failed rep under a loaded bar is a different problem from a failed rep on a leg extension.
• Rest: 3 minutes after heavy squats, 90 to 120 seconds on everything else. Legs are the body part where short rests cost the most reps.

An eight-week progression

Two leg sessions a week, one squat-led and one hinge-led, so the heavy work on each pattern is separated by several days.

Increment: 5 kg on squats and deadlifts while it keeps working, 2.5 kg once it stops. How much weight to add and when covers what to do at the point the jumps get too big.

Legs at home

Harder than chest or arms at home, because the legs are strong and bodyweight is a fixed load. It is still workable, and the answer is unilateral work plus long ranges plus higher reps.

From GymEvo's library, no equipment: Squat, Paused Squat, Bulgarian Split Squat, Forward Lunge, Walking Lunges, Step-Ups, Pistol Squat, Sissy Squat, Jump Squat, Hip Thrust, Nordic Hamstring Curls, Single-Leg Calf Raise.

The two worth singling out:

• Nordic hamstring curls are the only serious bodyweight hamstring exercise. Hook your heels under something solid, lower yourself forward as slowly as you can, and push back up with your hands. Hard from the first session, and scalable by how far you let yourself fall.
• Bulgarian split squats put one leg under most of your bodyweight through a long range, which is close enough to a real training stimulus that they carry a home leg program on their own.

Progressing: reps to the top of the range, then a harder single-leg variation, then a loaded backpack, then tempo and pauses at the bottom. Progressive overload with bodyweight and calisthenics covers the order.

What to track

Leg exercises are where logging pays off most, because the numbers are large and the sessions are unpleasant enough that memory rewrites them. Nobody accurately recalls what they squatted for eight three weeks ago.

GymEvo's free tier records weight, reps and RPE per set, shows last session's numbers on the set you are about to do, and charts estimated one-rep max and total volume over your full history. If the squat chart is flat for two months, that is the answer to why the legs are the same size. See how GymEvo handles progressive overload.

Common mistakes

• Treating squats as the whole leg program. They barely touch the hamstrings and do nothing for the calves.
• Half-depth squats with more weight. The stretched portion is where the evidence points. Depth you can control beats plates you cannot.
• Prone leg curls by default. Use the seated machine if your gym has one.
• Bouncing calf raises. Full stretch, pause, drive up. Weight matters less than range here.
• One leg day a week. Twenty hard sets across quads, hamstrings, glutes and calves in a single session means the last exercises get nothing. Split it into two.
• Skipping the hinge because deadlifts are tiring. Romanian deadlifts at moderate weight give you most of the hamstring benefit for a fraction of the fatigue.

A note on load: squats and deadlifts are the lifts where technique failure under fatigue actually hurts people. If you are new to them, learn the pattern at a light weight before you chase the progression table, and stop a set when form changes rather than when the reps run out.
