What a box jump trains, and who it suits
A box jump is a vertical jump with a raised finish. The take-off is where the work happens: hips, knees and ankles straighten together in a fraction of a second, driven by the glutes, quads and calves, with the hamstrings and trunk joining in. The box then cuts the landing short. Instead of absorbing a full fall back to the floor, you meet the box near the top of the jump, which is why coaches use it to practise the take-off without the hard landing of repeated jumps on the floor.
It is an intermediate exercise. You need to squat, lunge and land a small jump on the floor with control before a box adds anything, and the plyometric training guide lays out the steps from landings to box work. In a session, box jumps go after the warm-up and before heavy lifting, while your legs are fresh. They sit alongside the squats, lunges and presses in the leg training guide.
Setting up: the box, the height and your stance
- Use a box made for jumping, ideally a soft foam plyo box, on a flat floor where it cannot slide. Stacked plates, benches and storage crates are not jump boxes.
- Start low, somewhere between mid-shin and knee height for most people. You should land with your hips clearly above your knees, not folded into a deep squat.
- Stand about a foot's length from the box, feet hip-width apart, weight over the middle of your feet.
- Check the space around you: no plates, dumbbells or people in the path of the arm swing or a missed jump.
- Warm up with a few bodyweight squats and small jumps on the spot before the first rep onto the box.
How to do a rep
- Swing your arms back as you dip into a quarter squat, hips back and chest up.
- Drive the arms forwards and up and jump straight up from both feet, straightening hips, knees and ankles together.
- Lift your knees and reach your feet onto the box, so the whole of each foot lands on top, both at once.
- Land quietly in a quarter squat, knees in line with your toes, and hold the landing for a second.
- Stand tall on the box to finish the rep, then step down one foot at a time and reset before the next jump.
Breathe in on the dip and out as you leave the floor. The cue to remember is 'jump high, land low': jump higher than the box needs, so you meet it on the way down instead of scrambling up onto it. A loud landing usually means stiff legs or a box that is too high.
Mistakes to fix first
| Mistake | What it looks like | The fix |
|---|---|---|
| A box that is too high | You land in a deep squat with your knees near your chest | Lower the box until you land with your hips above your knees |
| Knees caving in on landing | The knees drift towards each other as you touch down | Use a lower box, land with feet hip-width apart and keep your knees over your toes |
| Jumping down off the box | Every rep ends with a drop to the floor and a rebound | Step down, one foot at a time |
| Toes catching the edge | The front of the foot clips the box or only half the foot lands | Stand slightly further back, lift your knees more and reach the whole foot onto the top |
| Rushing the reps | Jumps follow each other with no reset and get lower each time | Reset your feet and your breath after every rep |
| Jumping when tired | Box jumps saved for the end of a hard session or a long circuit | Put them early, and end the set when the height drops |
If your knees or Achilles tendons hurt during or after jumping, stop and get it checked by a doctor or physiotherapist before you jump again. During pregnancy, ask your doctor or midwife before doing any jump training.
Box height, stepping down and other versions
Most questions about this exercise come down to three things: how high the box should be, how to get off it, and versions that change the take-off.
Box height: how high should the box be?
Lower than you think. The height of the box shows how high you can tuck your feet, not how high you jump, so a tall box mostly tests hip mobility and nerve. Start between mid-shin and knee height, and raise it only when every landing is quiet and your hips stay above your knees. Plenty of athletes train on boxes well below their maximum for exactly that reason.
Step down or jump down?
Step down. Jumping off the box adds a drop landing to every rep, the same load as a depth jump, which is an advanced exercise in its own right. Stepping down one foot at a time keeps the work on the take-off and keeps hard landings out of a set that is meant to train the jump.
Seated box jump
Sit on a bench or a low box with your feet flat, then jump from the seat straight onto a box in front of you. Starting from a stop takes away the bounce of the dip, so your legs have to produce force from a dead start. It needs a stable seat placed close to the jump box, so set it up with a coach the first time.
Box jump-over
Jump onto the box and step or hop off the far side, or clear it in one jump, then turn and go back. It is a conditioning drill for circuits and race-style training more than a power exercise, so use a low, soft box and step off once you tire. Add a burpee between jumps and it becomes the burpee box jump-over.
Every box taken, or not ready for one yet? Squat jumps and broad jumps on the floor train the same take-off, and the step-up builds the single-leg strength that jumping relies on. A low step box is fine for step-ups but is not a jump box.
Sets, reps and progression
| Goal | Sets × reps | How hard |
|---|---|---|
| Learning the jump | 3 × 3–5 | Low box, every landing silent, a full reset between reps |
| Building power | 4–6 × 3–5 | Every jump at full effort; end the set if the height drops |
| Conditioning circuits | Short sets of 5–8 on a low box | Steady and never rushed, stepping down every rep |
Rest fully between power sets, often a minute or two, because a tired jump is a slower jump. Count every jump as a foot contact; the plyometric training guide explains how to keep the weekly total sensible.
Progress quality before height: first make every landing quiet on a low box, then add a set, then raise the box a small step. One or two box jump sessions a week, kept away from your hardest leg day, suit most people. While your squat and lunge are still improving, strength work will do more for your jump than extra jumping.
Box jumps at RPM
RPM's floor photos show soft plyo boxes in the functional area in Al Manhal, beside the turf lane, the sled and the battle ropes. The photos cannot show which heights are on hand, so check them on a free guided tour, and ask a coach before you jump onto anything that is not a plyo box. A personal training session is a quick way to have your take-off and landing checked, and functional training at RPM covers the rest of that area.
Questions, answered.
What muscles do box jumps work?
The glutes, quads and calves drive the jump, the hamstrings help extend the hips, and the trunk keeps you steady in the air and on landing. Box jumps train how fast those muscles produce force more than how much muscle you build.
Box jump vs step-up: which should I do?
They do different jobs. The step-up is a slow single-leg strength exercise you can load with dumbbells; the box jump trains speed with your bodyweight. Most people should build the step-up first and add box jumps once their landings are under control.
What is the difference between a box jump, a squat jump and a depth jump?
A squat jump lands back on the floor, so every rep includes a full landing. A box jump lands higher, which shortens it. A depth jump starts by stepping off a box and jumping up the moment you touch the floor: it is the most demanding of the three and is usually kept for trained athletes with coaching.
What can I do instead of box jumps with no box?
Squat jumps, broad jumps or tuck jumps on a floor that does not slip train the same take-off. Keep the reps low, land softly and stop when the height drops.
Are box jumps good for beginners?
Not as a first exercise. Learn to squat, lunge and land small jumps on the floor, then start on a low, soft box. The leg training guide shows the strength work that comes before it.
What kind of box should I buy for home?
A soft foam box forgives a missed jump better than a wooden or steel one, and a box with three usable heights gives you room to progress. Check it is wide and heavy enough not to tip, and use it on a floor where it cannot slide.
