Cutting the dip to a shallow bounce keeps you springing off the floor in quick rhythm, which is what makes this conditioning rather than a strength move. Work in timed rounds of 20-30 seconds: the partial knee bend keeps ground contacts short and the heart rate high compared with a full-depth jump squat.
How to do the Half Squat Jump
- Stand with your feet shoulder-width apart.
- Bend your knees and lower your body into a squat position.
- Jump explosively, extending your hips and knees while swinging your arms for momentum.
- Land softly on the balls of your feet and immediately go into the next repetition.
- Repeat for the desired number of repetitions.
Tip: Screw the feet into the floor and spread it apart to keep the knees out and the arch of the foot from collapsing.
Muscles worked
Primary
Cardio · Cardio
High rep squats push the heart rate up more than any other lift, so leave enough rest between heavy sets.
Secondary
- Quads — The quads extend the knee and drive you out of the bottom, and front squats and close stance variations put more on them.
- Hamstrings
- Calves
Common mistakes
- Knees caving inward — push the knees out over the toes on the way up, especially out of the bottom where they most want to collapse.
- Hips shooting up first — if the hips rise faster than the chest on the way up, you turn the squat into a good morning; drive the chest and hips up together.
- Cutting the depth — get the hip crease below the top of the knee on every rep unless mobility genuinely stops you, in which case work on it.
- Losing the brace — take a big breath into the belly before each rep and hold it through the sticking point, then exhale on the way up.
Where it fits in a workout
Squats go first in a lower body session when you are freshest. Follow them with Romanian deadlifts or leg press, or superset lighter sets with pull-ups to use the same rack.
How many sets, how heavy and how hard: see what the ACSM position stands support.
Variations and alternatives
When to talk to someone
- Chest discomfort, feeling faint or lightheaded, or trouble breathing during or after exercise can be signs of a heart attack. In the US, call 911 right away; elsewhere, call your local emergency number.
- Heart, metabolic or kidney disease, or symptoms like these when you are active: talk to your doctor before you start or step up training.
- Pregnant: ask your obstetric care provider which exercise suits you.
