Single Leg Push-off
The single-leg push-off is a low-amplitude plyometric drill: you drive off one leg to hop up onto a low box or step, then reset and repeat. It builds single-leg power and teaches your quad and calf to work through one full stride at a time instead of sharing the load between two legs. Beginners use it to build the balance and force output that later plyometric work and change-of-direction drills depend on.
Why it works
Because the movement loads one leg only, the quadriceps has to produce and absorb force without help from the opposite leg, which is the same demand a running stride, a stair sprint, or a lateral cut places on your body. The calves and hamstrings assist as secondary movers, extending the ankle at push-off and controlling the hip and knee on landing. Training this pattern in isolation, rather than only inside two-leg jumps, closes the strength gap between your dominant and non-dominant leg that shows up in sports and in everyday stumbles. It also gives you an early, honest read on whether one leg is noticeably weaker or less stable than the other, something a two-leg jump can hide by letting the stronger leg pick up the slack.
Set up
- Stand facing a step, low box, or sturdy curb no higher than knee height.
- Balance on one leg with a slight bend in the knee and hip.
- Keep your free leg relaxed and slightly behind you for balance.
- Fix your eyes on a point ahead, not down at your feet.
How to do it
- Load your standing leg by bending the knee and hip slightly, like the bottom of a small squat.
- Drive through the ball of your foot and extend your ankle, knee, and hip in one motion.
- Push off the ground and step or hop up onto the box with the same leg.
- Land on the box with a soft, bent knee, absorbing the impact rather than stomping down.
- Step back down under control and reset your balance before the next rep.
- Complete all reps on one leg before switching sides.
Form cues
- Drive through the whole foot, not just the toes.
- Land quiet, not loud.
- Keep your hips level through the push.
- Chest up, don't lean forward to generate momentum.
Breathing: Exhale sharply as you drive off the ground, and inhale as you reset your stance before the next rep.
Common mistakes
Leaning the torso forward to build momentum instead of driving from the leg.
Fix: Keep your chest tall and let the push come from ankle, knee, and hip extension.
Landing with a locked knee.
Fix: Land with a soft bend in the knee to absorb force through the joint's muscles, not its end range.
Rushing straight into the next rep before regaining balance.
Fix: Pause and reset your stance for a full second before pushing off again.
Skipping the box entirely and just hopping in place.
Fix: Use an actual step or box so the movement has a clear target height and a defined landing to control.
How to program it
- Since this is a low-amplitude plyometric drill rather than a high-impact jump, 2 to 3 sets of 5 to 8 reps per leg fit well as part of a warm-up or a lower-body power block.
- Pair it with a hip hinge or single-leg strength move like a step-up so the leg gets both a power stimulus and a strength stimulus in the same session.
- Twice a week is plenty for most people; the limiting factor tends to be landing quality, not muscle fatigue, so stop a set once your landings get sloppy rather than chasing a rep count.
Safety notes
- Choose a box or step height you can land on with control; taller isn't better for this drill.
- Skip it on a day when your ankle or knee already feels irritated from other training.
- Train on a non-slip surface with supportive shoes.

Frequently asked questions
How many reps of single-leg push-offs should I do?
Most people do well with 2 to 3 sets of 5 to 8 controlled reps per leg, stopping a set as soon as the landings start to feel sloppy.
Can I do single-leg push-offs without a box?
Yes. Use a low step, a sturdy curb, or even a thick stack of books. The height matters less than landing with control.
What's the difference between this and a single-leg stride jump?
The push-off moves you up onto a surface and resets each rep, while the stride jump sends you forward in a continuous bounding pattern. Push-offs are the simpler entry point.
Why does my ankle feel tired after this exercise?
The calf and ankle absorb a lot of the landing force in a single-leg drill. If the fatigue is muscular rather than joint pain, that's the exercise doing its job; ease off if you feel a sharp or joint-level ache instead.
Is the single-leg push-off safe for beginners?
Yes, as long as you start with a very low step and only raise the height once your balance and landing control feel solid on both legs.
