The quadriceps are the biggest muscle group on the front of your thigh, and they’re the muscle doing most of the work every time you squat, lunge, step up, or walk up a flight of stairs. A cable machine isn’t the first tool most lifters reach for when they train quads. The barbell squat and the leg machines at your gym usually get that job. But a cable stack has one thing neither of those gives you: constant tension. The resistance pulls on your leg through the entire range of motion, from the bottom of a squat to the top of a lockout, instead of going slack at the point where a barbell or a machine would let up.
That constant tension changes how your quads experience a set. A cable can also load your leg from an angle a barbell can’t reach, like pulling you forward into a deeper squat or resisting your knee as it locks out on a single leg. That makes cable training a genuinely useful addition to a quad routine on its own, well beyond something to fall back on when the squat rack is busy. It’s also one of the friendlier ways to train quads if your knees or lower back need a break from carrying a bar, since you’re not loading your spine the way you would with a back squat. You can push a set close to failure on a cable without worrying about bailing out from under a loaded bar, which matters more than people give it credit for once the reps get hard.
I picked the 6 cable exercises below because each one trains your quads through a real, useful range of motion. You’ll get the benefits, the step-by-step setup, and a demo video for every exercise, plus a sample cable-only quad workout, a quick anatomy rundown, and answers to the questions I get most about training quads with cables.

Cable Goblet Squat
Benefits of the Cable Goblet Squat
The cable pulls you forward as you descend, which counterbalances your bodyweight and lets you sit back into a deeper squat than most lifters manage with a barbell or a dumbbell goblet squat. That extra depth means more knee flexion, and more knee flexion means more work for your quads, especially the vastus muscles at the bottom of the rep. It’s also one of the easier squat variations to teach, since the cable gives you instant feedback the moment you round your back or let your chest drop. I start a lot of newer lifters here before moving them onto a barbell squat.
How to Perform the Cable Goblet Squat
- Attach a single handle or V-bar to a low pulley and stand facing the machine.
- Grab the handle with both hands and hold it at chest height like a goblet squat, elbows pointing down.
- Step back until the cable is taut, feet about shoulder-width apart.
- Bend your hips and knees to squat down, keeping your chest up and the cable pulling straight through your arms.
- Drive through your heels and midfoot to stand back up.
Equipment: cable machine, low pulley, handle or V-bar attachment.
This video from Live Lean TV Daily Exercises shows how to perform the low cable goblet squat.
Set the pulley on its lowest setting so the cable pulls from as close to the floor as possible. If it’s set too high, you’ll feel the tension pulling you up and out of the bottom of the squat instead of holding you in it. Lean your torso back slightly as you descend and let the cable do the counterbalancing. Fighting the pull and staying bolt upright defeats the point of the exercise and just turns it into a harder version of a regular goblet squat. For more on which muscles this and other squat variations train, see our squat muscles worked breakdown.
Cable Bulgarian Split Squat
Benefits of the Cable Bulgarian Split Squat
A rear-foot-elevated split squat is already one of the best single-leg quad builders you can do, and adding a cable keeps tension on your leg through the bottom of the rep, right where a dumbbell would normally go weightless for a moment as it changes direction. Training one leg at a time forces each side to work on its own, so a stronger leg can’t bail out a weaker one the way it can on a bilateral squat. Expect your front leg to feel this hardest through the last few inches of the descent, where your quad is stretched the most.
How to Perform the Cable Bulgarian Split Squat
- Attach a handle to a low pulley and set a bench a few feet behind you, between you and the machine.
- Hold the handle at chest height with both hands and rest the top of your back foot on the bench.
- Bend your front knee to lower your back knee toward the floor, keeping your torso upright.
- Drive through your front foot to stand back up.
- Finish all your reps on one leg, then turn around and switch sides.
Equipment: cable machine, low pulley, handle, bench.
This video from The Green Door Life shows how to perform the cable Bulgarian split squat.
Start with a lighter weight than you’d guess. Balance is the limiting factor here before your quad strength is, and a load that feels manageable on a regular split squat can tip you over once one foot is up on a bench. Set the bench height so your back knee reaches the floor, or gets close to it, at the bottom of the rep. Too high a bench cuts your range of motion short and takes away most of the stretch that makes this exercise worth doing in the first place.
Cable Reverse Lunge
Benefits of the Cable Reverse Lunge
A reverse lunge is easier on your knees than a forward lunge, since your front foot is already planted on the ground when you load it instead of landing under load with momentum behind it. The cable adds resistance you can’t get from bodyweight alone, and because the line of pull is closer to horizontal than vertical, your quads and glutes have to work through the whole rep to keep you balanced, from the moment your foot leaves the floor through the drive back up. I use this one with lifters who want a single-leg quad exercise but find a Bulgarian split squat too demanding on balance early on, since the reverse lunge lets you reset your footing between every single rep.
How to Perform the Cable Reverse Lunge
- Attach a handle to a low pulley and stand facing the machine, holding the handle at chest height with both hands.
- Step back with one foot into a lunge position, keeping the cable taut the whole time.
- Bend your front knee to roughly 90 degrees and lower your back knee toward the floor.
- Push through your front foot to return to standing.
- Finish all your reps on one leg, or alternate legs each rep, depending on which feels more stable for you.
Equipment: cable machine, low pulley, handle.
This video from SET FOR SET’s exercise library shows how to perform the cable reverse lunge.
Keep most of your weight on your front foot the entire time. Your back foot is there for balance, and letting it help push you back up turns the exercise into more of a calf and glute movement than a quad one. Take a slightly longer step back than you think you need. A short step shifts the work toward your glutes, while a longer one keeps your knee tracking over your foot and your quad doing the bulk of the work.
Cable Step-Up
Benefits of the Cable Step-Up
A regular step-up already leans hard on your quads, since your whole bodyweight lands on a single bent knee with every rep. The cable adds resistance without needing a heavy dumbbell in each hand, which is usually the limiting factor on a loaded step-up long before your legs give out. Set the box height so your hip sits roughly level with, or slightly below, your knee at the top of the step. Go higher than that and you’ll start recruiting more glute. Go lower and you cut into the range of motion your quads get to work through.
How to Perform the Cable Step-Up
- Attach a handle to a low pulley and set a step or box a few feet in front of it.
- Hold the handle at chest height and place one foot fully on top of the box.
- Drive through that foot to bring your other leg all the way up onto the box.
- Step back down with control, leading with the same leg you stepped up with.
- Finish all your reps on one leg, then switch sides.
Equipment: cable machine, low pulley, handle, step or box.
This video from Jim Stoppani, PhD shows how to perform the cable step-up.
Push through your whole foot, heel included, rather than rising up onto your toes, and avoid pushing off your back leg to help yourself up. If you need momentum from the trailing leg to get to the top, the box is too high or the weight is too heavy for where you’re at right now. A 12 to 18 inch box works for most lifters, but adjust it to your own height and hip mobility rather than copying a number off this page.
Cable Terminal Knee Extension
Benefits of the Cable Terminal Knee Extension
This is the one exercise on this list that trains knee lockout specifically, the last 15 to 20 degrees of extension that a squat or lunge barely touches. It’s a staple in knee rehab programs because it builds the vastus medialis, the teardrop-shaped muscle just above your inner knee, without putting much load through the knee joint itself. I use this as a finisher after the heavier exercises above, or on its own on a day when my knees need a lighter session. For more single-joint options like this, see our isolation quad exercises guide.
How to Perform the Cable Terminal Knee Extension
- Attach an ankle cuff to a low pulley and strap it around one ankle, standing facing away from the machine.
- Step forward until the cable is taut, and bend the working knee slightly.
- Squeeze your quad to straighten your knee fully, without leaning back or shifting your hips.
- Slowly bend your knee back to the starting position, keeping tension on the cable the whole time.
- Finish all your reps on one leg, then switch sides.
Equipment: cable machine, low pulley, ankle cuff attachment.
This video from Flip Fitness shows how to perform the cable terminal knee extension.
Keep the range of motion small on purpose. This exercise works the last few degrees of extension, so a big swinging bend at the knee just turns it into a worse leg extension. A slight bend at the start is all you need. Hold the fully locked-out position for a full second on every rep instead of bouncing straight back into the next one. That pause is where most of the value in this exercise comes from.
Cable Leg Extension
Benefits of the Cable Leg Extension
This is the closest thing to a leg extension machine you’ll find on a cable stack, and it isolates your quads about as well as anything on this list. The cable’s resistance comes from the side or behind instead of straight down like a machine’s weight stack, so the strength curve feels a little different, with more tension in the fully lengthened position at the bottom of the rep. That makes it a solid complement to a leg extension machine if your gym has one, and a fine substitute when it’s busy or you’re training somewhere without one. For a deeper look at the muscles this trains, see our leg extension benefits and muscles worked guide, or check our leg extension alternatives if you want more single-joint quad options.
How to Perform the Cable Leg Extension
- Attach an ankle cuff to a low pulley and strap it around one ankle.
- Sit on a bench facing away from the machine, or stand facing away from it, with the working leg extended forward and the cable taut.
- If seated, hold the edge of the bench for support. If standing, brace your torso so it doesn’t sway.
- Extend your knee to bring your lower leg up until it’s roughly parallel to the floor, or straight out in front of you if you’re standing.
- Lower back down under control, then repeat before switching legs.
Equipment: cable machine, low pulley, ankle cuff attachment, bench (optional for the seated version).
This video from Live Lean TV Daily Exercises shows how to perform the standing cable leg extension.
The seated version is more stable and lets you focus on the squeeze at the top. The standing version adds a balance demand that also lights up your core and your standing leg’s glute, so pick whichever fits what you need that day. If your gym’s cable pulley doesn’t sit low enough for a clean seated setup, the standing version is the easier one to make work on almost any machine.
Cable-Only Quad Workout
Here’s a full quad session built from the 6 exercises above, in the order I’d run them. Rest 90 seconds to 2 minutes between sets on the compound exercises and 60 to 90 seconds on the isolation work at the end.
| Exercise | Sets | Reps |
|---|---|---|
| Cable Goblet Squat | 3 | 10-12 |
| Cable Bulgarian Split Squat | 3 | 8-10 per leg |
| Cable Reverse Lunge | 3 | 10 per leg |
| Cable Step-Up | 3 | 8-10 per leg |
| Cable Leg Extension | 3 | 12-15 per leg |
| Cable Terminal Knee Extension | 2 | 15 per leg |
The goblet squat goes first since it’s the exercise you can load the heaviest and it warms up your knees and hips for everything after it. The single-leg exercises come next while you’re still fresh, since balance gets harder to hold once fatigue sets in. The terminal knee extension closes things out. It’s light enough to do after your legs are already tired, and it gives your knees a bit of direct work right when the rest of the session has them warmed up.
Quad Anatomy
Your quadriceps are actually four muscles, not one, and all four sit on the front of your thigh and share a single tendon that attaches below your kneecap.
- Rectus femoris: runs down the middle of your thigh and is the only one of the four that crosses your hip joint as well as your knee. It helps extend your knee and flex your hip, which is why it’s worked hard in exercises like the step-up and lunge that involve lifting your leg forward as well as straightening it.
- Vastus lateralis: sits on the outside of your thigh and is the biggest of the four muscles by volume. Squats and split squats hit it hard, especially through a deep range of motion.
- Vastus medialis: sits on the inside of your thigh, just above your knee, and is the muscle most active in the last few degrees of knee extension. This is the one the terminal knee extension is built to target.
- Vastus intermedius: sits underneath the rectus femoris, deep in the middle of your thigh, and works alongside the other three on every knee extension exercise on this list.
All four muscles work together to extend your knee, which is the movement behind every squat, lunge, and step-up you do. If you want to zero in on the outside sweep of your thigh specifically, see our outer quad exercises guide for options that lean harder on the vastus lateralis.
Frequently Asked Questions
Can you build your quads with just a cable machine?
Yes, as long as you’re loading the cable heavy enough and progressing it over time. Your quads respond to tension and volume, not to the specific tool that provides it. The one thing a cable stack can’t do as well as a barbell is let you load a bilateral squat pattern with truly heavy weight, since most stacks top out well below what a strong lifter can back squat. If pure strength is your main goal, pair these cable exercises with a barbell squat rather than replacing it outright. If you’re training at home or at a gym without a squat rack, the single-leg exercises on this list, run hard and progressed over months, will still build real quad size on their own.
What’s the best cable exercise for quad size?
The cable goblet squat and the cable Bulgarian split squat do the most work here, since both let you load a deep range of motion under real tension. Between the two, I’d lean on the split squat a bit more for size specifically, since training one leg at a time lets you push each side closer to failure without your grip or your lower back becoming the limiting factor first. Add the cable leg extension at the end of either one for extra volume once the compound work is done, since your quads will already be warm and the isolation work will finish them off without beating up your joints.
How many sets of cable quad exercises should you do per week?
Somewhere around 10 to 16 total sets per week across all your quad exercises, cable or otherwise, is a reasonable range for most lifters chasing size. If you’re already squatting and leg pressing on other days, count those sets toward that total instead of adding these on top of a full leg day without adjusting anything else. Two cable quad sessions a week, spaced a few days apart, is plenty if you’re also doing barbell work. Three is fine if cables are your main tool and your legs are recovering well between sessions.
Is a cable squat as effective as a barbell squat for your quads?
For building muscle, a cable goblet squat done through a full range of motion gets you most of the way there. For building maximum strength, the barbell squat wins, since you can load it far heavier than a cable stack allows. I treat the two as complements. The cable version is great for warming up, for teaching depth and positioning, and for lifters whose backs don’t tolerate a loaded barbell well that day.
Can you do cable quad exercises with knee pain?
Often, yes, but it depends on what’s causing the pain. The terminal knee extension and the leg extension are both common choices in physical therapy because they let you strengthen the quad without loading the knee joint under a full squat or lunge pattern. I’m not a physical therapist, and if you’ve got real knee pain rather than normal training soreness, get it looked at before you load it further, on a cable or anything else.
Final Thoughts
If you only have time to run two or three of these, I’d pick the cable goblet squat and the cable Bulgarian split squat as your main work, then add the terminal knee extension as a short finisher if your knees can use the extra attention. Those three cover a deep bilateral squat, a hard single-leg exercise, and direct work on knee lockout, which is most of what your quads need from a training session. The rest of the list is there for when you want to rotate in variety or you’re stuck training somewhere with nothing but a cable stack and a bench. None of these exercises need to replace your squat. They’re a genuinely good way to add quad volume on days when a barbell isn’t the right tool, or your body needs a break from carrying weight on your spine.
