How to perform Star Jump
- Begin in a relaxed stance with your feet shoulder width apart and hold your arms close to the body.
- To initiate the move, squat down halfway and explode back up as high as possible. Fully extend your entire body, spreading your legs and arms away from the body.
- As you land, bring your limbs back in and absorb your impact through the legs.
Muscles worked
- Quads (primary): extends the knee to drive squats, lunges and jumps.
- Calves (secondary): points the foot to power push-off and steady the ankle.
- Glutes (secondary): extends and stabilises the hip — the engine behind hinges, squats and sprints.
- Hamstrings (secondary): bends the knee and extends the hip through hinges and pulls.
- Shoulders (secondary): raises and rotates the arms and drives everything overhead.
Sets & reps by goal
| Goal | Sets × reps | Load | Rest |
|---|---|---|---|
| Strength | 3–5 × 3–5 | Heavy (~85%+) | 2–3 min |
| Hypertrophy | 3–4 × 8–12 | Moderate (~65–75%) | 60–90 s |
| Endurance | 2–3 × 15–20 | Lighter (~50–60%) | 30–45 s |
Bodyweight movement: once you own the top of a rep range, progress by slowing the tempo, pausing at the hardest point, or moving to a harder variation instead of adding load.
Form tips
- Keep the knees tracking in line with the toes and push the whole foot into the floor.
- Own the largest range you can control with clean form before you chase extra reps.
- Land softly through the whole foot with bent knees to absorb the force, and reset fully between reps.
- Warm up the pattern with a couple of lighter, submaximal sets before your working sets.
Common mistakes
- Letting the knees cave inward as you push out of the bottom.
- Cutting the range short to squeeze out extra reps instead of owning each full one.
- Landing stiff-legged or with locked knees, which spikes the load on the joints.
