Single Leg Hop — Slow Each Box: A Complete Guide
Quick Intro
Single Leg Hop — Slow Each Box is a hop-and-hold drill performed by hopping through the Agility Ladder — Single Leg Hop pattern on one leg, holding a full second of stillness in each rung before hopping to the next one, prioritizing single-leg balance and control over pace. It’s dosed by full passes per leg and functions less like a speed drill and more like a single-leg stability exercise built inside the ladder’s spacing.
Equipment Needed
Single Leg Hop — Slow Each Box needs one Agility Ladder, laid flat on the ground, the only equipment this drill requires.
Why Single Leg Hop — Slow Each Box Matters
Holding each landing still for a full second asks the calf (gastrocnemius) and deeper calf muscle (soleus) to absorb the hop and then keep the ankle quiet through the entire hold. The front of the thigh (quadriceps, rectus femoris), glutes (gluteus maximus) and back of the thigh (hamstrings, biceps femoris) drive each hop and then have to sustain that landing position without the momentum a faster pace would provide. The outer hip (gluteus medius) and hip flexors (iliopsoas) work to keep the standing leg stacked and the pelvis level for the full duration of every hold, a longer demand than any faster pace places on either. The shin and inner thigh, both busy at faster paces, have little to do here, since there’s no quick foot clearance or fast lateral correction for either to manage. Balance is the main demand, ahead of agility, a direct result of turning a hop into a held, single-leg stance. Coordination comes with it.
When to Do It
This drill fits best as a dedicated balance piece early in a session, before fatigue sets in, since holding a stable single-leg landing takes concentration that fades once the legs tire. It also works well on its own as single-leg stability training, separate from any agility-focused session, given how directly its demand overlaps with balance work done elsewhere.
Anyone with a current ankle, knee or hip issue should still approach this carefully, since sustaining weight on one leg for a full second removes any momentum that might otherwise help mask an unstable landing.
Getting Ready
A few minutes of easy jogging raises blood flow to the legs before single-leg holds begin. A handful of standalone single-leg balance holds, away from the ladder, previews the sustained stillness this version depends on before the hopping and spacing get added.
Step-by-Step Instructions
1. The setup. Take a single-leg stance at one end of the ladder, the non-hopping leg lifted and the ladder’s full length ahead.
2. The first hop. Hop softly into the first rung, landing on the ball of the foot with a slightly bent knee.
3. The hold. Hold that landing completely still for a full second, keeping the hips level and the standing leg quiet, before hopping again.
4. The continuation. Repeat the hop-and-hold sequence down the full length of the ladder, staying on the same leg the entire way, then rest and switch legs.
How Many, How Often
Single Leg Hop — Slow Each Box is dosed by full passes per leg, with the one-second hold in every rung taking priority over how many passes get completed.
| Level | Where you’re at | What to do |
|---|---|---|
| Beginner | New to holding a single-leg landing under load | 1 pass per leg, with a full second of stillness in every rung, even if that means resting between rungs. |
| Intermediate | The hold stays still through most of a pass on both legs | 1 to 2 passes per leg, working toward zero wobble in every hold. |
| Advanced | Both legs hold a still landing through a complete pass | 2 passes per leg, or move toward Agility Ladder — Single Leg Hop once holds stay rock-solid throughout. |
Holding each landing completely still for the full second matters more here than finishing the ladder quickly, since the pause itself, not the hop, is the point.
Modifications and Variations
Single Leg Hop — Slow Each Box has one progression, the pattern it builds toward.
For more difficulty, Agility Ladder — Single Leg Hop removes the held pause between rungs and asks the same single-leg hopping to continue rung to rung without stopping.
Progression path: a stable, still landing gets built here first, one rung at a time with nothing else to think about; the continuous version then asks that same stability to hold up without a pause to reset between hops.
Common Mistakes to Avoid
Cutting the hold short instead of finishing a full second. Rushing into the next hop before the landing has settled defeats the entire purpose of a drill built around sustained control. Counting the hold deliberately, even out loud at first, keeps the pause full length.
Letting the standing leg wobble instead of staying quiet. Small, constant corrections during the hold are a sign the landing hasn’t stabilized, even if the foot never fully leaves the rung. Working toward stillness, not just staying upright, is what this drill trains.
Treating this as a warm-up instead of a training piece. Because the pace is slow, it’s easy to rush through this version without focus, but sustained single-leg control at this level takes just as much concentration as a faster drill, only in a different form. Giving each hold full attention is what builds the stability this version is meant to develop.
After Your Set
The standing leg’s calf and outer hip take on a sustained load through a full set of held landings, so a couple of minutes of easy movement is a reasonable way to transition into stretching. A standing calf stretch, one heel pressed back against the floor with the front knee bent, releases the calf (gastrocnemius) and deeper calf muscle (soleus) that held quiet through every landing. A standing side-on hip stretch, crossing one leg behind the other and leaning the hips toward the wall, opens the outer hip (gluteus medius) that kept the pelvis level through every sustained hold.
Going Deeper
This version is a different kind of drill using the same ladder spacing: where every other pace in this pattern rewards moving well, this one rewards standing still on one leg without any help from momentum. That distinction is worth remembering, since training it as a faster hop misses what makes this version useful.
Progress here tends to stall on the hold quietly shortening under fatigue, not on the hop itself: an athlete can hold a full, still second early in a pass and let that hold shrink to a half-beat once the standing leg starts to tire. Resting fully between rungs protects the training effect this version exists to deliver.
Someone new to this drill generally needs several sessions before a full second of stillness feels reliable on both legs, since sustained single-leg balance is a skill that develops more slowly than footwork speed does.
How to Know You’re Improving
- Every landing holds completely still for a full second, without cutting the pause short
- The standing leg stays quiet through the hold, without small, constant wobble corrections
- Both legs hold comparably still, not just the stronger one
- A full pass finishes without the holds shortening late in the set
Stillness held for the full second on both legs, not how many rungs get completed, is what marks progress here.
Muscles Worked
- Gastrocnemius (a calf muscle, holding the ankle still through a pause in every box)
- Rectus Femoris (a front thigh muscle that crosses both the hip and knee, supporting a held single-leg position between hops)
- Gluteus Maximus (the largest glute muscle, settling the hip before the next hop is allowed)
- Biceps Femoris (a muscle at the back of the thigh, working with the glute to stop the knee wobbling on the pause)
- Iliopsoas (the deep hip flexor, keeping the free leg quietly lifted during the hold)
- Soleus (a deeper calf muscle beneath the gastrocnemius, making the small constant corrections that keep the balance)
- Gluteus Medius (a smaller glute muscle at the side of the hip, carrying most of the balance work in the held position)
FAQ
Does the held landing work the same muscles as the continuous hop? Mostly. A held, still landing never calls on the quick foot clearance or fast lateral correction that faster hopping needs, so the shin and inner thigh have much less to do (see Why It Matters above).
Is this an agility drill or more of a balance exercise? It’s closer to a balance and landing-control exercise that happens to use the ladder’s spacing, which is why balance, not agility, is the main demand of this version (see Why It Matters above).
Why does this version emphasize a full second of stillness? Because the skill being trained here is control at the landing itself, not how quickly the ladder gets covered, so this version is stability training in the form of ladder work (see Quick Intro above).
Should I rest between rungs if the hold keeps shortening? Yes. Resting briefly between rungs to reset a full-second hold is a better use of a set than pushing through with holds that keep getting shorter, since a shortened hold trains a different, less useful pattern.
