Single Leg Butt Kick
Single leg butt kicks take the familiar running warm-up drill and isolate it to one leg, hopping in place while flicking your heel up toward your glute in quick succession. It builds the fast hamstring flexion running requires while forcing your standing leg to absorb and reset each small hop. It's a light, beginner-friendly way to prime your legs before a run or a lower-body session.
Why it works
The quick heel-to-glute flick comes from rapid hamstring contraction, but your quadriceps do most of the primary work here because they control the small hop and re-extend your hip and knee to reset for the next kick. Your calves absorb each landing and help produce the next tiny bounce, similar to what happens during ground contact in a real sprint. Doing it on one leg at a time also exposes any side-to-side difference in ankle stability or rhythm that a standard two-leg version can hide.
Set up
- Stand tall with your hands loose at your sides or bent at 90 degrees like a light jog.
- Shift your weight onto one leg, keeping a soft bend in that knee.
- Pick a spot ahead of you to focus on for balance.
- Clear a small patch of floor since you'll be hopping in place.
How to do it
- Push off the standing leg into a small hop.
- As you hop, flick your heel up toward your glute on the same leg.
- Land softly on the ball of your foot and immediately hop again.
- Keep the rhythm quick and light, more like a bounce than a jump.
- Complete your reps on one leg, then switch and repeat on the other.
Form cues
- Keep the hops small and quick, height isn't the point here.
- Land on the ball of your foot, not flat-footed.
- Keep your torso tall instead of hunching forward to help the kick.
- Let your arms swing lightly to help set the rhythm.
Breathing: Keep your breathing quick and natural through the set, the same way you'd breathe during any light jog.
Common mistakes
Trying to kick as high as possible instead of keeping the rhythm quick.
Fix: Focus on speed and a light landing rather than how close your heel gets to your glute.
Landing flat-footed on each hop.
Fix: Land on the ball of your foot so your calf can absorb the impact and spring you into the next rep.
Leaning forward at the waist to help flick the heel up.
Fix: Keep your torso upright and let your hamstring do the work instead of your posture.
How to program it
- This is a light warm-up drill, not a conditioning load, so 15 to 20 seconds per leg for 2 rounds is enough to prime the muscles involved.
- It fits well at the start of a running or lower-body session, right after general mobility work and before your first sprint or heavy set.
- Daily use is fine since the impact per hop is small and the drill is meant to wake up your legs, not fatigue them.
Safety notes
- Keep the hops small if your balance feels shaky, a wobble that turns into a hard landing is more likely to strain something than the drill itself.
- Do it on a flat, even surface with good footwear, uneven ground makes the single-leg balance demand much harder to manage safely.

Frequently asked questions
How long should I do single leg butt kicks for?
15 to 20 seconds per leg for 2 rounds is plenty as a warm-up drill, since the goal is priming your legs, not building fatigue.
Can I do single leg butt kicks without much space?
Yes, since you're hopping in place rather than traveling forward, a couple of square feet of clear floor is all you need.
Single leg butt kicks vs regular butt kicks, what's the difference?
Regular butt kicks travel forward or jog in place on both legs, spreading the balance demand across two feet. The single-leg version isolates one side at a time, which exposes and trains any difference in rhythm or stability between your legs.
Why can't I balance during single leg butt kicks?
Balancing through a repeated hop on one leg is a skill on its own, separate from strength. Slow the tempo down and keep the hops small until your ankle and hip stabilizers catch up, it usually improves quickly with practice.
