Agility Ladder — Lateral In-Out: A Complete Guide
Also called Agility Ladder — Side Step
Quick Intro
Agility Ladder — Lateral In-Out, also called the Agility Ladder Side Step, is a sideways footwork drill performed by facing sideways along an agility ladder and stepping both feet into a rung, then both feet out to the side, before advancing to the next rung down the ladder’s length. It’s dosed by passes through the ladder and trains lateral footwork in a plane the standing sprint tests never touch.
Equipment Needed
Agility Ladder — Lateral In-Out needs one Agility Ladder, laid flat on the ground, the only equipment this drill requires.
Why Agility Ladder — Lateral In-Out Matters
Moving sideways down the ladder shifts the emphasis onto the outer hip (gluteus medius) and inner thigh (adductors), the two muscles most directly responsible for controlling a leg as it steps sideways into and out of a rung. The front of the thigh (quadriceps, rectus femoris) and calf (gastrocnemius) drive each step, the muscle along the outside of the hip and thigh (IT band, TFL) helps stabilize the leg through the lateral motion and the hip flexors (iliopsoas) and glutes (gluteus maximus) work together to lift and plant each foot. The deeper calf muscle (soleus) and shin (tibialis anterior) manage the quick, repeated ground contacts throughout. Agility is the main demand of this drill. Speed matters too, since a fast, controlled lateral pace is a speed demand even without covering ground forward.
When to Do It
This drill fits well in the same session as the forward-moving ladder patterns, giving the hips and legs a different plane of movement to work through while the legs are still fresh. It also works as a standalone frontal-plane conditioning piece on its own.
Anyone with a current hip, knee or ankle issue should approach this carefully, since lateral footwork loads the outer hip and the inner thigh in a way straight-ahead running never does.
Getting Ready
A few minutes of easy jogging or side-to-side shuffling raises blood flow to the hips and legs before the ladder demands quick lateral steps. A slow walkthrough of the pattern, stepping both feet in and both feet out at a deliberate pace, confirms the footwork before adding speed.
Step-by-Step Instructions
1. The setup. Stand facing sideways at one end of the ladder, feet together just outside the first rung.
2. The step in. Step the near foot into the rung, then bring the far foot in to meet it.
3. The step out. Step the near foot out to the far side of the rung, then bring the far foot out to meet it, advancing the whole body one rung down the ladder.
4. The continuation. Repeat the in-and-out pattern down the full length of the ladder, keeping the hips low and the chest up throughout.
How Many, How Often
Agility Ladder — Lateral In-Out is dosed by passes through the ladder, run once in each direction to train both sides evenly.
| Level | Where you’re at | What to do |
|---|---|---|
| Beginner | New to lateral ladder footwork | 3 to 4 passes per direction, slow and deliberate, focused entirely on a low, controlled base. |
| Intermediate | The in-and-out pattern stays clean at a steady pace | 4 to 5 passes per direction at a controlled, rhythmic pace. |
| Advanced | The pattern holds together at speed in both directions | 5 to 6 passes per direction, or try Agility Ladder — Lateral In-Out — Both Directions to combine both into a single continuous pass. |
Keeping the hips low and level through every step matters more here than how fast the ladder gets covered, since a base that pops up between steps loses the stability this drill is built to train.
Modifications and Variations
Agility Ladder — Lateral In-Out has one alternative.
As an alternative that changes the technique, Agility Ladder — Lateral In-Out — Both Directions combines a pass moving one way with an immediate pass moving back the other way, training the same footwork as one continuous, direction-reversing sequence.
Progression path: the in-and-out pattern mastered moving one direction at a time first, then combined into a single continuous back-and-forth sequence once each direction feels equally clean.
Common Mistakes to Avoid
Standing tall through the step instead of staying low. A tall stance leaves the hips too high to control the lateral step, and it’s what turns a controlled drill into a wobbly, off-balance one. Keeping the hips low and the knees slightly bent through every step protects the outer hip and keeps the base stable.
Training one direction far more than the other. Practicing lateral footwork in the stronger direction only leaves the weaker side underdeveloped, a gap that shows up the moment a game or sport demands cutting toward that side. Running an equal number of passes in each direction closes that gap over time.
Crossing the feet instead of stepping them together. Letting the trailing foot cross in front of or behind the leading one turns this into a different footwork pattern entirely and increases the chance of a misstep. Bringing the feet together, not crossed, at the end of every step in and every step out keeps the pattern clean.
After Your Set
The outer hip and inner thigh absorb a repeated load through a full set of lateral passes, so a couple of minutes of easy movement is a reasonable way to transition into stretching. A standing side-on hip stretch, crossing one leg behind the other and leaning the hips toward the wall, releases the outer hip (gluteus medius) that controlled every lateral step. A seated groin stretch, soles of the feet together and the knees eased down toward the floor, opens the inner thigh (adductors) that worked to close every step.
Going Deeper
This drill pairs naturally with the forward-moving ladder patterns, since together they cover both the sagittal and frontal planes a sport or game demands. It also works well right before agility work that includes a direction change, since the lateral control this drill builds carries directly into a sharper plant-and-cut later in the same session.
Progress here tends to stall on the weaker direction specifically, not on the pattern as a whole: an athlete can look smooth moving one way and noticeably rougher moving the other, since most people naturally favor one side without realizing it. Running extra passes specifically toward the weaker direction, rather than simply repeating the pattern evenly, tends to close that gap faster.
Someone new to lateral ladder work generally needs a few sessions to find a low, stable base in both directions, and continues sharpening pace over the following few weeks once that base feels automatic.
How to Know You’re Improving
- The hips stay low and level through every step, with no rise between rungs
- Both directions look equally clean, with no obvious favored side
- The feet come together cleanly on every step in and every step out, with no crossing
- The same controlled pattern holds up as pace increases toward full speed
A base that stays low and even in both directions, not raw pace, is what marks progress here.
Muscles Worked
- Gluteus Medius (a smaller glute muscle at the side of the hip, pushing the lead foot out to the side of the rung)
- Adductors (the inner thigh muscles, pulling the trailing foot in to meet the lead one)
- Rectus Femoris (a front thigh muscle that crosses both the hip and knee, keeping a soft knee through the sideways travel)
- Gastrocnemius (a calf muscle, bouncing between the in and out positions)
- IT Band and Tensor Fasciae Latae (a band of connective tissue running down the outside of the thigh, tightening each time the weight shifts to one side)
- Iliopsoas (the deep hip flexor, lifting the foot just clear of the rung on the step in)
- Gluteus Maximus (the largest glute muscle, holding the hips from sinking as the pattern speeds up)
- Soleus (a deeper calf muscle beneath the gastrocnemius, steadying the ankle through the narrow footwork)
- Tibialis Anterior (a muscle along the front of the shin, keeping the toes raised so the feet clear the rungs)
FAQ
Why train lateral footwork at all if most sports involve forward sprinting? Almost no sport is purely linear: cutting, shuffling and reacting sideways all draw on the same frontal-plane control this drill trains directly, a demand the straight-ahead sprint tests don’t cover on their own (see Why It Matters above).
Is it normal for one direction to feel noticeably easier than the other? Yes, and it’s worth noticing, since most people have a dominant side. Deliberately running more passes toward the weaker direction is a reasonable way to close that gap (see Going Deeper above).
What’s the difference between this and Agility Ladder — Two Feet In Each Box? Two Feet In Each Box moves straight down the ladder in the sagittal plane, while this drill moves sideways in the frontal plane, asking the outer hip and inner thigh to do work the forward pattern never demands (see Muscles Worked above).
Can I use this as a warm-up for a sport that involves a lot of cutting? A few slow, controlled passes work well as a warm-up primer for the hips and outer legs, though a full working set at speed is better placed as its own conditioning piece (see When to Do It above).
