Why train legs on machines
Machines are not a lesser version of squats and deadlifts. They trade balance and skill for stability, and for building muscle that trade is often worth it. A leg press lets you take the quads close to failure without worrying about your lower back or a bar on your shoulders. A leg curl trains the hamstrings at the knee, which no barbell lift does well.
- Easy to learn: set the seat, read the sticker on the machine, start lifting. Good for your first months in the gym.
- Safe to push hard: you can stop at any point and there is no bar to bail. That makes the last reps of a set productive instead of risky.
- Small, exact jumps: stacks usually go up in 5 kg (10 lb) or smaller steps, which suits double progression.
- Joint friendly options: people with sore knees or backs can often still train on a leg press or leg curl with a reduced range.
- The downside: machines do not train balance or the stabilising muscles, and settings vary between brands. Add one free weight or single leg move if you can.
Leg machines in most gyms
The leg machine workout
| Machine | Sets x reps | Rest | Why it is here |
|---|---|---|---|
| Leg press | 4 x 8 to 12 | 2 to 3 min | Heaviest quad and glute work of the day |
| Seated or lying leg curl | 3 x 10 to 12 | 90 s | Hamstrings at the knee |
| Leg extension | 3 x 10 to 15 | 90 s | Quads, including the rectus femoris that the press trains less |
| Hip abduction machine | 3 x 12 to 15 | 60 s | Side glutes (gluteus medius and minimus) |
| Hip adduction machine | 2 x 12 to 15 | 60 s | Inner thighs |
| Standing or seated calf raise | 3 x 10 to 15 | 60 s | Calves |
Start with the leg press while you are fresh, because it moves the most weight and needs the most effort. Then alternate between the back and front of the thigh: the leg curl rests the quads before the leg extension finishes them. The two hip machines are light and quick, and can be done back to back as a pair. Calves come last; the calf exercises hub has more options for them.
Machine setup: the details that matter
| Machine | Setup | Common mistake |
|---|---|---|
| Leg press | Feet hip width, mid platform. Lower until the knees are at about 90 degrees or a bit deeper, as long as your lower back stays on the pad | Lowering so deep that the hips roll off the seat |
| Leg extension | Knee joint lined up with the machine's pivot, pad just above the ankle | Seat too far back, so the knee is in front of the pivot |
| Lying leg curl | Knees just off the edge of the pad, roller above the heels | Hips lifting to swing the weight up |
| Seated leg curl | Knee lined up with the pivot, thigh pad pressing down firmly | Thigh pad loose, so you slide out |
| Hip abduction | Sit tall, pads outside the knees, push out and pause | Bouncing the stack between reps |
| Hip adduction | Start at a stretch you can control, squeeze the legs together | Starting too wide on the first set |
Write down the seat and pad settings on each machine. A hole lower on the seat can change how heavy a weight feels, and you want week to week numbers you can compare.
Glute exercises on machines
The glutes do a lot on a leg day, but on machines you can bias them deliberately. These are the glute machine exercises most gyms have:
- Leg press, feet high and wide: more hip bend, more glute work. Push through the heels.
- Hip abduction machine: trains the side glutes that keep the knee stable. Leaning forward a little shifts it toward the upper glutes. See the hip abduction machine guide.
- 45 degree back extension: round the upper back slightly and push the hips into the pad to turn it into a glute exercise.
- Glute kickback machine or cable kickback: one leg at a time, hip straightens behind you, pause at the top.
- Hip thrust machine: if your gym has one, it is the easiest way to load the glutes heavily without setting up a bar.
For a full glute day with free weights as well, see the glute exercises hub.
Inner thigh machine and Smith machine leg workout
Inner leg workout on the machine
The adductors on the inner thigh are big muscles that also help in squats and leg presses. The hip adduction machine trains them directly. You cannot burn fat from the inner thigh by training it, but you can make the muscles stronger and fuller. Two to three sets of 12 to 15 once or twice a week is plenty.
Smith machine leg workout
A Smith machine fixes the bar on rails, so it works as a squat or lunge machine. Good options:
| Exercise | Sets x reps | Rest |
|---|---|---|
| Smith machine squat, feet slightly in front | 3 x 6 to 10 | 2 to 3 min |
| Smith machine split squat or reverse lunge | 3 x 8 to 12 per leg | 90 s |
| Smith machine Romanian deadlift | 3 x 8 to 12 | 2 min |
| Smith machine hip thrust | 3 x 10 to 12 | 90 s |
| Smith machine calf raise on a step | 3 x 10 to 15 | 60 s |
Beginner and advanced versions
Beginner leg machine workout
| Machine | Sets x reps | Rest |
|---|---|---|
| Leg press | 3 x 10 to 12 | 2 min |
| Seated leg curl | 2 x 10 to 12 | 90 s |
| Leg extension | 2 x 12 to 15 | 90 s |
| Seated calf raise | 2 x 12 to 15 | 60 s |
Start with a weight you could lift for about 15 reps and stop at 10 to 12. Over the first weeks you will add weight quickly while you learn how hard a set should feel. For a full first program, see the beginner workout plan.
Advanced leg machine workout
| Machine | Sets x reps | Rest | Technique |
|---|---|---|---|
| Hack squat or leg press | 4 x 6 to 10 | 3 min | Heavy, 1 to 2 reps short of failure |
| Lying leg curl | 3 x 8 to 12 | 90 s | Last set: drop the weight and keep going |
| Single-leg leg press | 3 x 10 to 12 per leg | 90 s | Evens out a weaker side |
| Leg extension | 3 x 12 to 15 | 60 s | 2 second hold at the top |
| Hip adduction | 3 x 12 to 15 | 60 s | Slow lowering |
| Standing calf raise | 4 x 8 to 12 | 60 s | Pause 2 seconds in the stretch |
Drop sets suit machines well because changing the pin takes seconds. Keep them for the last set of an isolation exercise. On a push pull legs split, this can be your second leg day of the week after a barbell squat day.
How to progress on leg machines
Pick a rep range per machine, such as 8 to 12 on the leg press. Add reps each session at the same weight. When every set reaches 12, move the pin one step and start again near 8. That is double progression, and machines make it simple because the weight jumps are small and the movement is the same every time.
If the stack runs out on the leg extension or leg curl, slow the lowering to 3 seconds or switch to single leg sets. Keep the leg press honest: if the depth shrinks as the weight goes up, it is not progress. The leg workout hub shows how a barbell leg day fits alongside this one.
Gripp remembers your machine numbers
Gripp is coming to iPhone. Log each set and it tells you what to do next on every machine: last time 10 reps at 140 kg (310 lb) on the leg press, today go for 11. Fill the range in every set and the weight goes up. Each exercise keeps an estimated 1RM on a progress chart, and Gripp rates your leg strength against people of your age and bodyweight.
