Agility Ladder In-In-Out-Out

The agility ladder in-in-out-out is a forward footwork drill with two steps inside each square and two outside. It trains coordination, quick foot placement, and lower-body conditioning.

How to do it

  1. Stand facing the ladder just before the first square, with your knees slightly bent.
  2. Step your right foot into the first square.
  3. Step your left foot into the same square beside your right foot.
  4. Step your right foot outside the right edge, level with that square.
  5. Step your left foot outside the left edge, level with that square.
  6. Repeat the four-step pattern in each successive square, moving forward along the ladder.
  7. Walk forward beyond the ladder after the final sequence.

Form cues

  • Keep your contacts quiet.
  • Look a few squares ahead.
  • Let your arms swing naturally.

Common mistakes

  • Stepping too far outsidePlace each outside step just beyond the ladder's edge to keep the pattern compact.
  • Bouncing upwardKeep your head at a steady height rather than hopping between foot placements.
  • Losing the sequenceSay “in-in-out-out” to maintain an even four-step rhythm.

Safety

Catching a rung can cause a trip or fall. A misplaced sideways step can roll your ankle, especially when speed or fatigue reduces control.

  • Lay the ladder flat on a level, nonslip surface.
  • Leave clear space on both sides and beyond the ladder for your exit.
  • Practice at walking pace before increasing speed.
  • End the set when your foot placement becomes unreliable.

If you have ankle instability, lower-limb pain, or balance difficulties, use a slower forward-only drill or seek guidance from a physiotherapist first.
