Poliquin Step-Up

The Poliquin step-up is a single-leg, VMO-focused step-up onto a low box with the heel elevated, driving the knee forward over the toes. Named after strength coach Charles Poliquin, it's a knee-over-toes builder used within the ATG method — here's how to do it with good form, the muscles it works, the mistakes to avoid, and how to program it.

The Poliquin step-up is a single-leg, knee-dominant step-up onto a low box with the heel elevated, which lets the knee travel forward over the toes to emphasize the quadriceps — especially the VMO (the teardrop quad above the knee) — with the glutes assisting. It's named after the late strength coach Charles Poliquin, who used it to target the VMO, and it's now widely used within the ATG (knees-over-toes) method popularized by coach Ben Patrick. Keep the box low, drive the knee forward, step up under control, and lower slowly.

Muscles worked

The heel-elevated setup drives the knee forward over the toes, which loads the quads through a deep knee angle and emphasizes the VMO. The glutes assist as you stand up onto the box.

How to Poliquin step-up

Step-by-step form for the Poliquin step-up. If you're new, keep the box low and start with bodyweight.

  1. Set up on a low box. Stand facing a low box with the working foot on it, forefoot planted and the heel elevated slightly so the knee can travel forward.
  2. Drive the knee forward. Let the working knee travel forward over the toes as you shift your weight onto the box, keeping the movement slow and controlled.
  3. Step up. Push through the working leg to stand up onto the box, driving mostly from the front leg rather than pushing off the floor with the trailing foot.
  4. Lower slowly. Reverse the movement under control, lowering back down with the knee still tracking over the toes. Keep the box low enough that you stay pain-free.
The low box is the point — it keeps the knee-forward range controlled. Resist the urge to raise it before your bodyweight reps are smooth and comfortable.

Common mistakes

Variations & alternatives

If you want to train the same knee-over-toes pattern with a different setup or emphasis, these are the common swaps:

ATG split squat (deep single-leg) Patrick step (ankle + VMO) Loaded step-up with dumbbells (progression) Lower box / assisted (regression) Slant-board squat (heel-elevated, both legs)

How to program it

The Poliquin step-up fits leg day or a knee-focused warm-up as part of the ATG (knees-over-toes) method from coach Ben Patrick — building on the VMO work first popularized by strength coach Charles Poliquin. General starting points:

GoalSets × repsNotes
Build the range2–3 × per legLow box, bodyweight, slow control, stop short of pain
Strength & size3–4 × per legAdd light dumbbells once bodyweight reps are clean; keep the knee tracking forward
Frequency1–2× / weekProgress by earning more range first, then load or reps

Pair it with the ATG split squat and the Patrick step for a full knees-over-toes lower-body block.

Track it in LiftHero

Log every Poliquin step-up set — box height, reps, and any load — in LiftHero, and it charts your progressive overload and flags personal records so you can watch your range and strength climb over the weeks. You can add warm-up sets, note left vs right, and drop the movement into a saved routine so it's ready the next time you train. LiftHero records what you log; it doesn't diagnose your form.

Frequently asked questions

What muscles does the Poliquin step-up work?

It primarily trains the quadriceps with a strong emphasis on the VMO (the teardrop quad above the knee), because the heel-elevated setup drives the knee forward over the toes. The glutes assist as you stand up.

Who is the Poliquin step-up named after?

It's named after the late strength coach Charles Poliquin, who used heel-elevated, knee-forward step-ups to target the VMO. It's now widely used within the ATG knees-over-toes approach popularized by Ben Patrick.

How high should the box be?

Start low. A low box lets the knee travel forward through a controlled, pain-free range without overloading the joint. Raise the box only once you can perform clean, comfortable reps.

Do I need to hold weight?

No. Bodyweight is plenty to start while you build the range and control. You can add light dumbbells as a progression once your form and range are solid.

How many sets and reps should I do?

A few working sets per leg of moderate reps is a common starting point. Progress by earning more range and control first, then adding load or reps over time.
