In-In-Out-Out — Forward

Quick Intro

In-In-Out-Out — Forward is a ladder footwork drill performed by moving forward through an agility ladder with the Agility Ladder — In-In-Out-Out four-count pattern, both feet in and both feet out, facing the direction of travel throughout. It’s dosed by passes through the ladder and is the standard, more accessible orientation of the drill, meant to be mastered before the backward direction adds a spatial-awareness demand on top of it.

Equipment Needed

In-In-Out-Out — Forward needs one Agility Ladder, laid flat on the ground, the only equipment this drill requires.

Why In-In-Out-Out — Forward Matters

Facing forward through the pattern, the outer hip (gluteus medius) and inner thigh (adductors) still control each leg’s in-and-out step in close coordination with its pair, while the front of the thigh (quadriceps, rectus femoris) and hip flexors (iliopsoas) drive all four quick placements. The calf (gastrocnemius) manages the ground contacts, the back of the thigh (hamstrings, biceps femoris) helps control each foot’s return and the shin (tibialis anterior) lifts each foot clear on the way in and out. Facing forward, the muscle along the outside of the hip and thigh (IT band, TFL) and the lower back (erector spinae) have less to do than they do once the backward orientation removes direct sight of the ladder. Agility is what this version asks for most, with speed and coordination a step behind.

When to Do It

This drill fits well as the entry point into the four-count in-in-out-out pattern, since learning the footwork facing forward removes the added spatial-awareness demand the backward direction eventually introduces. It works well early in a ladder session, once the legs are warm and full attention can go toward the sequence itself.

Anyone with a current ankle or knee issue should approach this carefully, since the four quick ground contacts per rung add up to plenty of repeated impact over a full pass, even facing forward.

Getting Ready

Blood flow to the legs comes up with a few minutes of easy jogging before the quick four-count rhythm starts. Walking through the sequence slowly in just the first box, feeling each of the four placements land in order, is worth doing once before the pace picks up.

Step-by-Step Instructions

1. The setup. Set up at one end of the ladder with the feet together just behind the first rung, squared up to face forward.

2. The double entry. Bring one foot into the rung and follow immediately with the second, so both land inside it.

3. The double exit. Send the first foot back out to the side, then the second, moving the whole body toward the next rung.

4. The rhythm. Continue the in-in-out-out sequence facing forward through every rung to the end of the ladder.

How Many, How Often

In-In-Out-Out — Forward is dosed by passes through the ladder, with a clean, correctly-ordered four-count sequence taking priority over pace at every level.

Level	Where you’re at	What to do
Beginner	New to the four-count in-in-out-out pattern	4 to 5 slow passes, focused entirely on hitting all four placements in the correct order.
Intermediate	The four-count sequence stays consistent at a moderate pace	5 to 6 passes at a controlled, rhythmic pace.
Advanced	The sequence holds together facing forward at speed	6 to 7 passes, or move toward Agility Ladder — In-In-Out-Out once the forward pattern feels fully automatic.

Getting the sequence itself locked in matters more here than how fast the ladder gets covered, since this version exists specifically to build that foundation before direction gets added on top of it.

Modifications and Variations

In-In-Out-Out — Forward has one progression: the standard pattern run at a working pace.

For more difficulty, Agility Ladder — In-In-Out-Out takes the same four-count footwork to a full working pace. Beyond it, In-In-Out-Out — Backward reverses the direction of travel and adds a spatial-awareness demand on top of the sequence.

Progression path: the four-count pattern gets learned facing forward first, since the footwork alone is enough to focus on initially; the backward direction then adds a separate challenge once the forward sequence is already reliable.

Common Mistakes to Avoid

Rushing to the backward version before the forward sequence is reliable. Adding a reversed direction on top of a footwork pattern that isn’t solid yet tends to combine two problems into one confusing pass. Confirming the forward version feels automatic first makes the harder version far easier to learn.

Letting the feet linger on the ground between counts. Extra ground contact time on any of the four placements slows the whole rhythm down and works against the quick, precise footwork this drill is meant to build. Treating every placement as a touch-and-go keeps the rhythm quick.

Blending the two in-steps or two out-steps into one movement. Moving both feet at once instead of one after the other collapses the four-count sequence into a simpler two-count jump, training a different and less precise pattern. Keeping each of the four placements distinct builds the sequence this drill teaches.

After Your Set

A full set of this drill leaves the calves and outer hips well worked, so a couple of minutes of easy movement before stretching is worth the time. Pressing one heel back against the floor with the front knee bent, in a standing calf stretch, eases the calf (gastrocnemius) that absorbed every quick contact. Crossing one leg behind the other and leaning the hips toward the wall, in a standing side-on hip stretch, unwinds the outer hip (gluteus medius) that controlled every forward in-and-out step.

Going Deeper

Learning the four-count rhythm facing forward first makes the eventual backward direction dramatically easier to pick up than attempting both at once. It also works well as a standalone conditioning piece on its own, given how much the constant four-placement rhythm taxes cardiovascular and muscular endurance together even without the added backward demand.

What usually holds this drill back isn’t sequencing errors but lingering ground contacts: an athlete can hit all four placements in the right order and still look slow if any of them sits too long. Deliberately slowing the pace while consciously shortening each contact builds quickness faster than just trying to move the whole sequence faster.

Someone new to this drill generally needs a session or two to feel all four placements distinctly while facing forward, and continues sharpening ground contact time over the following few weeks before the backward version gets added.

How to Know You’re Improving

All four placements stay distinct and correctly ordered, with no blending of the two in-steps or two out-steps
Each of the four placements lands and leaves the ground noticeably quicker than it did in early attempts
The sequence holds together for a full pass without needing to consciously count each step
The forward pattern feels reliable enough that adding a reversed direction feels like a reasonable next step

How reliable the four-count sequence feels facing forward, not how fast the ladder gets covered, is what marks progress here.

Muscles Worked

Rectus Femoris (a front thigh muscle that crosses both the hip and knee, taking the landings with the ladder in full view)
Gluteus Medius (a smaller glute muscle at the side of the hip, driving the two steps out to the sides)
Iliopsoas (the deep hip flexor, feeding the knees forward along the line of travel)
Gastrocnemius (a calf muscle, bouncing the feet through the four-beat count)
Adductors (the inner thigh muscles, bringing the feet back inside the rung)
Biceps Femoris (a muscle at the back of the thigh, helping the foot leave the rung cleanly)
Tibialis Anterior (a muscle along the front of the shin, lifting the toes on the forward advance)

FAQ

Does facing forward change which muscles work? A little. Facing forward, the outer thigh and the lower back have less to do than they do once the backward direction removes direct sight of the ladder (see Why It Matters above).

Is this a separate exercise, or just the standard way to do the pattern? It is the standard pattern, practiced facing forward as a deliberate first step. The four counts stay the same later on; what changes is the pace and, in the backward version, the direction of travel.

Why does coordination matter less here than in the backward version? Moving with full visual feedback removes a coordination demand that the backward direction creates, so the same four-count footwork simply asks less of coordination while facing forward (see Why It Matters above).

How do I know I’m ready to try the backward direction? When the four-count sequence holds together for a full pass without needing to consciously count each step, this version has done its job. Agility Ladder — In-In-Out-Out at a working pace comes next, with In-In-Out-Out — Backward after it (see Modifications and Variations above).
