The In And Out Squats Jump Bodyweight is a beginner-level squat movement that trains the quadriceps using bodyweight. Because the primary movers contribute to the movement, the payoff shows up in overall performance in this pattern. What separates this variation from other quadriceps work is that it is with a jumping, ballistic component — a detail that changes which fibres take the load and how much stability the movement demands. The 'Out Squats Jump' element in the name is the part that matters technically — it defines the exact position and path this version uses, and swapping it changes the training effect. Support comes from the glutes, hamstrings, calves, and core; the glutes in particular help extend and externally rotate the hip, which is why fatigue there often shows up before the quadriceps is fully worked. Training this with bodyweight needs no equipment at all and can be done virtually anywhere, though it is harder to load progressively once you outgrow it. In a training week, this fits naturally into any session where quadriceps is the priority. The pattern is accessible enough to learn in a single session, which makes it a sound entry point before progressing to heavier or more complex variations.
Muscles Worked
The In And Out Squats Jump Bodyweight is primarily a legs exercise, but it is never only the legs doing the work.
Legs
75%
Glutes
42%
Hamstrings
32%
Calves
22%
Legs (primary) — These fibres contribute to the movement, and they carry the majority of the load in this movement.
Glutes (secondary) — Assists by helping to extend and externally rotate the hip, contributing to hip power, posture and lower-back protection.
Hamstrings (secondary) — Assists by helping to bend the knee and extend the hip, contributing to hip power, sprinting and knee joint balance.
Calves (secondary) — Assists by helping to point the foot downward at the ankle, contributing to ankle stiffness, walking and jumping mechanics.
Benefits of the In And Out Squats Jump Bodyweight
Reinforces the quadriceps, glutes and trunk stabilisers as a coordinated unit rather than as isolated parts.
The a jumping, ballistic component increases time under tension without needing heavier load.
Uses bodyweight, which needs no equipment at all and can be done virtually anywhere.
Builds strength in the quadriceps through a squat pattern, which carries over directly to bending and straightening the knees and hips together.
How to Perform the In And Out Squats Jump Bodyweight
1
Set your starting position and brace your core before the first rep.
2
Break at the hips and knees together, keeping your weight through the midfoot.
3
Descend to a depth you can control with a neutral spine.
4
A good In And Out Squats Jump Bodyweight rep looks identical to the one before it; when it doesn't, the set is done.
5
Drive back up through the floor, keeping the quadriceps working the whole way.
6
Breathe out through the effort and keep the quadriceps under tension between reps.

Breathing Technique
The general rule for the In And Out Squats Jump Bodyweight is simple: inhale and brace at the top, exhale through the ascent. For heavier sets, take a breath in at the start position, brace as though bracing for a punch, and hold that pressure through the hardest part of the rep before exhaling. Consistent breathing is what keeps your brace intact from the first rep to the last.
Tips for Proper Form
Track the knees in line with the toes and keep the mid-foot loaded.
Set your position before the first rep rather than correcting it mid-set.
Control the lowering phase — most of the quadriceps stimulus comes from resisting the weight, not lifting it.
Keep the range of motion consistent across every rep so you can compare sessions honestly.
Drive through your midfoot, not your toes — that keeps tension in the quadriceps instead of shifting it forward.
Expect to feel the In And Out Squats Jump Bodyweight in your glutes, hamstrings, calves and core as well as the quadriceps — that's normal, but if the glutes, hamstrings, calves and core fatigue first, revisit your setup.
Progress by changing leverage or tempo rather than adding reps forever — a slower rep loads the quadriceps more than ten fast ones.
Common Mistakes to Avoid
Letting the knees collapse inward as you stand up.
Do this insteadPush your knees out over your toes on the way up — cue it deliberately until it's automatic.
Copying someone else's In And Out Squats Jump Bodyweight setup without adjusting for your own build.
Do this insteadLimb lengths change what a good position looks like; adjust until you feel it in the quadriceps.
Letting the glutes compensate once the quadriceps tires.
Do this insteadStop the set at that point — past there you're training the compensation.
Variations by Experience Level
Beginner
Reduce the load and perform the In And Out Squats Jump Bodyweight for higher repetitions, focusing entirely on position rather than weight. Film one set of the In And Out Squats Jump Bodyweight from the side; it's the fastest way to spot what to fix.
Intermediate
Increase total working sets before increasing load — volume drives most of the adaptation at this stage. Hold your In And Out Squats Jump Bodyweight load for two sessions before increasing it.
Advanced
Progress to a heavier variation of the same pattern once technique is stable at your current load. At this level the In And Out Squats Jump Bodyweight is best programmed after your heaviest quadriceps work, not before it.
Safety Considerations
The a jumping, ballistic component increases time under tension, so reduce the load relative to what you would normally handle.
Stop the set when technique degrades — a In And Out Squats Jump Bodyweight rep that no longer looks like your first one is not building anything.
Warm up with lighter sets of the In And Out Squats Jump Bodyweight before your first working set.
The most common way the In And Out Squats Jump Bodyweight goes wrong is knees collapsing inward under fatigue.
Who Should Avoid This Exercise
The In And Out Squats Jump Bodyweight suits most healthy trainees, but it is not appropriate for everyone.
Anyone experiencing sharp, localised or radiating pain during the movement — that is a signal to stop, not to push through.
Anyone with an acute lower-back injury or disc irritation, until cleared to load the spine again.
This is general educational information, not medical advice. If you are managing an injury or medical condition, check with a qualified professional before adding this exercise to your programme.
What muscles does the In And Out Squats Jump Bodyweight work?
It primarily trains the legs, with the glutes, hamstrings, calves, and core assisting. The pattern is classified as squat, so the quadriceps, glutes and trunk stabilisers share the workload.
Is the In And Out Squats Jump Bodyweight suitable for beginners?
Yes. It is rated beginner-level, and the pattern can usually be learned in a single session with light resistance.
How many sets and reps should I do?
A practical starting point is 3 sets of 6-8, resting 2-3 min between sets, roughly 2x per week. Adjust from there based on how you recover.
What equipment do I need for the In And Out Squats Jump Bodyweight?
You need bodyweight. This needs no equipment at all and can be done virtually anywhere, though it is harder to load progressively once you outgrow it.
How do I breathe during the In And Out Squats Jump Bodyweight?
As a general rule, inhale and brace at the top, exhale through the ascent. Avoid holding your breath for the entire set.
What is the most common mistake with the In And Out Squats Jump Bodyweight?
Knees collapsing inward under fatigue. The simplest correction is to track the knees in line with the toes and keep the mid-foot loaded.
What can I do instead of the In And Out Squats Jump Bodyweight?
Good substitutes that train the same quadriceps pattern include Ball Headlock Squat, Barbell Jefferson Split Squat, and Barbell Side Step Up. Pick whichever matches the equipment you have available.
How often should I do the In And Out Squats Jump Bodyweight?
About 2x per week suits most people. Recovery, not frequency, is what limits progress.
About Training Your Quadriceps
Where the In And Out Squats Jump Bodyweight earns its place is repeatability — bodyweight makes the setup easy to reproduce, which is what lets you actually progress the quadriceps.
The quadriceps are the four large muscles on the front of the thigh that straighten the knee and drive almost every lower-body movement. They are among the biggest and most powerful muscles in the body, so training them hard pays off in strength, size, and athletic performance.
Squat and lunge patterns are the foundation of quad development — back squats, front squats, leg presses, split squats, and step-ups all load the quads heavily while also recruiting the glutes. Leg extensions isolate the quads directly for extra volume and a strong contraction. For most lifters, anchoring leg day with a heavy compound squat and finishing with lunges and extensions builds the most complete thighs.
Keep the knees tracking over the toes, descend to at least parallel where mobility allows, and control the lowering phase. Beginners should master bodyweight and goblet squats before loading a heavy barbell.
