Star Jumps
Star jumps load a quarter squat and explode upward, flinging arms and legs into a wide star before landing soft and compact. Maddy uses them to add jump power and fast conditioning for clients who are past basic jumping jacks. Coached by Maddy (NASM-CPT) — these are the exact form cues he gives on every client's first week.

Level — Intermediate
Intermediate; the star is easy — repeated soft, quiet landings are the actual skill.
Proper form — 5 cues
- Dip into a quarter squat with arms by your sides to load the jump.
- Drive through the whole foot and extend the hips completely at take-off.
- Spread arms and legs wide at the top — make the star shape in mid-air.
- Pull the limbs back in before you land, feet under hips.
- Land toes-to-heels with bent knees, sinking straight into the next dip.
Breathing: Inhale on the dip, exhale explosively through take-off, and let breathing settle between short sets.

Common questions
Star jumps vs jumping jacks — what's the difference?
A jumping jack keeps the feet skimming the floor and cycles continuously; a star jump is a genuine vertical jump with a squat load, full hip drive, and airborne shape. That makes star jumps a power exercise you dose in short quality sets, while jacks are a steady conditioning tool you can run for minutes. Beginners should own jacks and quiet squat landings before adding star jumps.
Are star jumps safe for beginners?
The movement is simple, but the impact is real. If you can perform ten controlled bodyweight squats and land a small jump quietly with bent knees, you are ready to start with low, submaximal star jumps in sets of five. If landings feel jarring or your knees complain, spend two weeks on squat holds and low pogo hops first — the jump will still be there.
How many star jumps should I do for a workout?
For power, keep it crisp: five sets of five maximum-effort jumps with two minutes rest, done fresh at the start of a session. For conditioning, use timed intervals — 20 to 30 seconds of continuous jumps with equal or longer rest, three to four rounds. Mixing the two goals in one set usually means doing neither well.
