The recipe for a great leg day, muscle by muscle.

Quads: the front of your legs

The quads are the big muscles on the front of your thigh, and they drive every squat, lunge, and press. These are the movements that build them, from heavy compounds down to a machine finisher.

Barbell back squat. Form matters more here than on almost anything else, but when it comes to classic movements and heavy loads, the sky's the limit. If you tend to feel it more in your glutes than your quads, try a small plate under your heels. It makes the movement more quad-dominant and can improve your squat depth too.

Goblet squat. Simple and intuitive, and very effective for beginners, though it gets tougher once you need heavier dumbbells to keep progressing. Because it's so quad-dominant, focus on driving up through the middle of your foot and your heels, pushing the ground away from you instead of thinking about pushing yourself up.

Bulgarian split squat. Elevating your rear foot on a bench puts your front leg fully in charge, which makes this one of the best single-leg quad and glute builders you can do. Don't let your front knee cave inward or travel too far past your toes. Keep your torso upright, your core braced, and drive through your front heel. The back leg is there for balance, not support.

Leg extension. A machine isolation move that targets your quads directly, with no other muscles helping out. It's best used as a finisher after your compound lifts. Don't swing the weight or use momentum. Hold for a second at the top of each rep, and control the movement on the way down.

Hamstrings: the back of your legs

The hamstrings run down the back of your thigh and handle hip hinging and knee bending. Train them with one hinge and one curl and you cover both jobs.

Romanian deadlift (RDL). The gold standard for hamstring development. Go single-leg if you want to isolate one side and work on your balance and stability at the same time. Keep the bar close to your legs and your knees slightly bent. That's what gets you a deep stretch as you load the hamstrings.

Lying leg curl. Your isolation option. Simple, effective, and an easy way to add hamstring volume without loading your lower back. Focus on the squeeze at the top of each rep. Most people rush these when they should be slowing down and really squeezing the hamstrings before lowering back down.

Glutes: power, shape, and strength

The glutes are the strongest muscle group in your body and the engine behind every hinge and jump. One dedicated movement goes a long way.

Barbell hip thrust. If you're serious about glute development, hip thrusts belong in your rotation. They're one of the most glute-focused moves there is. Your shins should be roughly vertical at the top, with your feet about shoulder-width apart. Too close together and you'll shift the work to your quads. Too far apart and it goes to your lower back.

Calves: don't skip them (please)

Calves get skipped more than any other muscle group on leg day. Don't be that person. They respond best to a full range of motion and higher reps.

Standing calf raise. Go through the full range of motion every rep. Drop your heel as far below the step as it'll go on the way down, and come up as high as possible at the top.

Building your leg day

You don't need to hit all nine of these in one session. That would be a lot. A well-rounded leg day usually looks something like this:

• One to two quad compounds (barbell squat, goblet squat, or Bulgarian split squat).
• One quad isolation (leg extension).
• One to two hamstring movements (RDL and lying leg curl).
• One glute movement (hip thrust).
• One calf movement (standing calf raise).

Pick your battles, train hard, and don't skip calves.
