Jump Squats
The jump squat is a plyometric exercise where you lower into a squat, then drive up explosively so your feet leave the floor, landing softly back into the next squat. It trains the quads, glutes and calves to produce force quickly, building lower-body power and conditioning with no equipment needed.

What muscles does the jump squats work?
Primary movers
- Quadriceps
- Gluteus maximus
- Calves
Assisting muscles
- Hamstrings
- Adductors
- Core
The jump squat uses the same muscles as a bodyweight squat but asks them to produce force much faster. The quads and glutes extend the knees and hips explosively, and the calves finish the push through the ankles.
Each landing is as important as the jump. The muscles absorb force eccentrically as you land and immediately reuse it for the next jump, a process called the stretch-shortening cycle. Training it improves how well your muscles and tendons store and return energy.
That quality underpins sprinting, jumping and changing direction, which is why jump squats are a core plyometric exercise for athletes.
Done for higher reps with short rest, the same movement becomes an intense conditioning exercise that raises the heart rate quickly.
How to do the jump squats
Setup
- 1
Stand with feet shoulder-width apart and toes turned slightly out.
- 2
Hold your hands in front of your chest or at your sides ready to swing.
- 3
Brace your core and stand tall.
Execution
- 1
Lower into a squat, sitting the hips back and down to about quarter or half depth.
- 2
Swing your arms back as you lower.
- 3
Drive up explosively through the whole foot, swinging the arms up as you jump.
- 4
Fully extend the hips, knees and ankles as you leave the floor.
- 5
Land softly on the balls of your feet and roll back to the whole foot, bending the knees to absorb the impact.
- 6
Go straight into the next rep, or reset between reps for maximum power.
Common jump squats mistakes
Landing stiff-legged
Landing with straight legs, which sends impact through the knees and hips instead of the muscles.
The fix: Land quietly with bent knees and hips, letting the legs act as shock absorbers.
Knees caving in on landing
Letting the knees collapse inward as you land, a common cause of knee injuries.
The fix: Keep the knees pushed out over the toes. Reduce the jump height until you can control the landing.
Squatting too deep
Sinking into a full deep squat before each jump, which slows the movement and reduces the power output.
The fix: Use a quarter to half squat depth for maximum explosiveness.
Doing too many reps
Grinding through long sets for power, so each jump gets lower and sloppier.
The fix: For power, keep sets short and rest well. Save high reps for conditioning.
How many sets and reps?
| Goal | Sets | Reps | Load | Rest |
|---|---|---|---|---|
| Power | 3–5 | 3–6 | Bodyweight, maximum height | 90 s–2 min |
| Conditioning | 3–4 | 10–20 | Bodyweight | 45–60 s |
| Beginner plyometrics | 2–3 | 5 | Bodyweight, stick each landing | 60–90 s |
For power, do jump squats early in a session when you are fresh, in short sets with full rest. For conditioning, use higher reps with short rest in a circuit. Beginners should practise landing first, pausing after each rep to stick the landing. Two plyometric sessions a week are plenty for most people.

Frequently asked questions
What muscles do jump squats work?
The quads, glutes and calves produce the jump, with the hamstrings, adductors and core assisting. The same muscles also absorb force on landing, which builds tendon resilience.
Are jump squats bad for your knees?
Not when you land softly with bent knees that track over the toes. Problems usually come from stiff landings, knees caving in or too many reps. Start with low jumps and focus on landing quietly.
Do jump squats burn fat?
They burn a lot of energy for their duration and are useful in conditioning circuits. Fat loss itself depends on overall diet and activity, not any single exercise.
How deep should I squat before jumping?
A quarter to half squat is ideal for power. It is deep enough to load the muscles and shallow enough to change direction quickly.
How many jump squats should I do?
For power, 3 to 5 sets of 3 to 6 maximum-effort jumps with full rest. For conditioning, 3 to 4 sets of 10 to 20 with short rest.
