Jump Squat: How to Do It, Muscles Worked and Benefits

A jump squat is a squat you finish by leaving the floor, and that small change turns a strength exercise into a power one. Instead of grinding through a rep, you are teaching your legs to produce force fast, which is the quality that separates someone who can squat a lot from someone who can sprint, jump and change direction. It needs no equipment, about two square metres of floor and considerably more attention to landing than most people give it.

How to do a jump squat

Start with bodyweight. Clear the space around you and, if you train upstairs or on concrete, put something forgiving underfoot.

1. Set up. Stand with your feet shoulder-width apart, toes turned out slightly, arms relaxed at your sides or hands lightly clasped at your chest.
2. Dip. Push your hips back and bend your knees into roughly a quarter to half squat. This is not a full-depth squat; going too deep kills the elastic response you are trying to use.
3. Explode. Drive through the middle of your foot and extend your hips, knees and ankles as hard and as fast as you can, swinging your arms up to help. Aim to be quick out of the bottom rather than deep in it.
4. Land soft. Meet the floor with the balls of your feet first, then let your heels settle, and bend your hips and knees to absorb the impact. The landing should be almost silent.
5. Reset. Take a breath, check your feet are still where you want them, then go again. Do not bounce straight into the next rep unless you are deliberately training reactive jumps.

Muscles worked

• Quadriceps. They extend the knee during the drive and then work eccentrically on landing to stop your knee collapsing. Most people feel jump squats in their quads the next day.
• Glutes. The glute max is the main hip extensor and it supplies a large share of the upward force. It also stops your knees falling inward as you land, which is why weak glutes and painful jumping so often go together.
• Hamstrings. They assist hip extension on the way up and help decelerate the knee on the way down.
• Calves. The final ankle push comes from the calves and Achilles, and the elastic recoil in that tendon is a big part of why a jump feels springy.
• Core and spinal erectors. They keep your torso upright through take-off and landing. Let them go and you fold forward mid-air.

Once bodyweight jumps feel easy, the goblet squat is the natural strength partner, because more squat strength gives you more force to convert into speed.

Benefits

It builds jumping and sprinting power. Plyometric work reliably improves vertical jump height, and a meta-analysis on training variables found that programmes running more than 10 weeks, with more than 20 sessions and over 50 jumps per session produced the biggest gains. Small doses do little; consistent ones do a lot.

It trains the part of squatting most people skip. Standard barbell work is slow by nature. Jump squats add the rate-of-force element that heavy squats alone cannot supply, and the evidence that plyometric training raises vertical jump height has been consistent for years.

It teaches you to land. Landing mechanics matter for anyone who plays sport. Practising controlled deceleration in a predictable setting is far better than discovering your knees cave in during a five-a-side game.

It needs nothing. No bar, no rack, no gym. Just floor and a bit of ceiling height, which makes it one of the best moves for training at home. The NHS asks adults to do muscle-strengthening activity on at least two days a week, and jump squats slot into that easily.

Common mistakes

Landing like a plank. Straight legs on impact send the force into your knees and lower back. Bend and absorb, every single rep.

Knees collapsing inward. Watch yourself from the front on a phone camera. If your knees dive towards each other as you land, stop jumping and spend a fortnight on glute work and squat technique first.

Squatting too deep before the jump. A full-depth squat kills the stretch reflex and turns the exercise into a slow grind. A quarter to half squat is where the power lives.

Turning it into cardio. Twenty rushed reps trains fatigue tolerance, not power. If you want the power adaptation, keep sets short and rest properly.

Doing them on concrete in old trainers. Repeated landings on an unforgiving surface are a reliable way to develop shin and knee pain. Some gym flooring or a thick exercise mat makes a real difference at home.

Variations

• Squat jump to a box. Jump up onto a low plyo box and step down. The box takes most of the landing impact out, so it is the version to use if your knees complain or you are carrying extra weight.
• Split squat jump. Start in a lunge, jump and swap legs in the air. Harder on balance and much harder on each leg individually, which makes it a good progression from the Bulgarian split squat.
• Dumbbell jump squat. Hold a light dumbbell in each hand at your sides. Keep the load modest; the moment the jump slows noticeably, the weight is too heavy.
• Continuous or reactive jump squats. Land and immediately jump again, spending as little time on the floor as possible. This trains the stretch-shortening cycle hard and should only be added once your landings are consistently quiet.
• Squat to calf raise. For anyone who cannot jump yet, squat and rise onto your toes instead. It teaches the sequence without the impact.

Sets and reps

• Power and athleticism: 3 to 4 sets of 5 to 8 reps, twice a week, resting 60 to 120 seconds between sets. Do them early in a session while you are fresh.
• Conditioning circuits: 3 sets of 12 to 15, resting 30 to 45 seconds, accepting that quality will drop and that this is a different training goal.
• Learning the landing: 3 sets of 5 low jumps, focusing entirely on landing quietly and keeping your knees out.

Progress by jumping higher rather than jumping more. When bodyweight reps feel easy and every landing is silent, add a light load or move to reactive jumps rather than pushing the rep count up. More on training at home in our workouts section.
