A good leg day covers four movement patterns: squat, hinge, lunge, carry. Six to eight working sets a week per major lower-body muscle drives consistent strength and muscle growth. This post sets out a beginner template and an intermediate template built on the Schoenfeld volume data, plus what to skip.

Why legs matter more than the rest

Lower-body strength predicts mortality and functional capacity more than any other muscle group in adult cohort data. Quadriceps strength predicts mortality more strongly than blood pressure, cholesterol or BMI in some datasets. Older adults with low quadriceps strength carry a 51-65% higher mortality risk than the high-strength group. For the wider muscle-priority picture, see my hub post on the most important muscle groups to train.

Beyond longevity, legs drive whole-body output. Sprint speed, jumping, lifting, gait stability and posture all run through the lower body. If you train one body part well, it should be your legs.

The four leg patterns to cover

Squat (knee-dominant). Quadriceps, glutes. Examples: back squat, front squat, goblet squat, leg press.

Hinge (hip-dominant). Hamstrings, glutes, lower back. Examples: Romanian deadlift, conventional deadlift, hip thrust, kettlebell swing.

Lunge (single-leg). Quads, glutes, hamstrings, balance. Examples: walking lunge, reverse lunge, Bulgarian split squat, step-up.

Carry / calf and core. Carries train grip, posture, calves. Calves themselves respond to slow-rep work. Examples: farmer carry, single-leg calf raise, standing calf raise.

A complete leg day touches all four patterns. Twice a week leg training is the evidence-supported frequency band for hypertrophy.

Beginner template (first 3 to 6 months)

Two leg sessions a week. 40-50 minutes each. Focus on technique and progressive load. 1-2 reps in reserve on every working set.

Exercise Sets x Reps Notes
Goblet squat 3 x 8-10 Knees track over toes, full depth
Romanian deadlift 3 x 8-10 Hinge from hips, soft knees
Reverse lunge 3 x 8 per leg Step back, drop straight down
Hip thrust or glute bridge 3 x 12 Squeeze glutes hard at top
Standing calf raise 3 x 15 Slow on the way down
Farmer carry 3 x 30-40m Heavy, shoulders down

Intermediate template (6+ months training)

Two split sessions a week. Squat-led one day, hinge-led the other. Each session sits at 45-60 minutes. Working sets at 1 RIR. Track loads and aim to add weight or reps each week.

Squat-led day

Exercise Sets x Reps Rest
Back or front squat 4 x 5 3 min
Bulgarian split squat 3 x 8 per leg 2 min
Leg press or hack squat 3 x 10-12 2 min
Seated leg curl 3 x 12 90 sec
Calf raise (standing) 4 x 12 60 sec

Hinge-led day

Exercise Sets x Reps Rest
Conventional or trap-bar deadlift 4 x 4 3 min
Barbell hip thrust 3 x 8 2 min
Romanian deadlift 3 x 10 2 min
Walking lunge 3 x 10 per leg 90 sec
Farmer carry 3 x 40m 90 sec

What to skip

Three patterns I see in beginner leg programmes that waste time or carry risk relative to gain.

Leg extensions as a staple. Useful as a finisher. Not a substitute for the squat or lunge. Pure isolation loads the knee tendon at long levers without the systemic stimulus of compounds.

Smith machine squats only. The fixed bar path removes the stabiliser work that drives most of the long-term function carryover. Use it occasionally for safety. Do not use it as the only squat.

Ego deadlifting. Deadlift form is the hardest to maintain at heavy loads. Stay at 1-2 RIR until form is genuinely automatic. The injury cost of one bad heavy day undoes weeks of progress.

Recovery and nutrition

Leg sessions need recovery. 48 hours between sessions for the same muscle group. Protein at 1.6g per kg per day to support adaptation. Sleep 7-9 hours. For the macronutrient frame, see the protein and fat post. For sleep, see the sleep post.

For training that fits a small space and budget, see the home workout post for a no-gym version of the same patterns.

Frequently asked questions

How many leg days a week is best?
Two. Twice-weekly leg training delivers the strongest hypertrophy effect in pooled meta-analyses.
Should I deadlift on leg day?
Yes. Deadlift is the heaviest hinge available and trains hamstrings, glutes, lower back and grip in one move.
Are squats enough for legs?
Squats build quadriceps and glutes well, hamstrings less so. Add a hinge pattern for the back of the leg.
How long should a leg session be?
45 to 60 minutes is the evidence-supported sweet spot. Beyond 75 minutes, fatigue accumulates.
Should beginners use a barbell?
Goblet squats and Romanian deadlifts with kettlebells or dumbbells are safer to learn. Move to the barbell once technique is reliable.
My knees hurt during squats. What now?
Reduce depth, slow the descent, and ensure knees track over toes. Persistent pain warrants physiotherapy assessment.

Bottom line

Two leg sessions a week. Cover squat, hinge, lunge and carry. 10 to 20 hard sets per muscle group across the week. 1-2 reps in reserve on working sets. Add a rep or a small load every week. The compound lifts do most of the work. Isolation fills the gaps.
