The pelvis should not move

Footwork is a leg exercise performed from a stable trunk. If the pelvis tips or the lower back lifts as you press, the trunk is contributing force it should not be, and the exercise has become something else.

A hand under the lower back gives immediate feedback. If pressure changes as you press, reduce the spring or the range.

The standard foot positions

Each position emphasizes different musculature, which is why the series runs through several rather than repeating one.

  • Toes on the bar, heels lifted — calves and quadriceps
  • Arches on the bar — balanced through the foot
  • Heels on the bar — hamstrings and glutes emphasized
  • Wide second position — adductors and external rotators
  • Single leg — doubles load and exposes asymmetry

Knee tracking

Knees should travel over the second toe throughout. Knees falling inward under load is the most common fault and usually indicates weak lateral hip musculature rather than a knee problem.

If it happens, reduce spring and range and add side-lying hip work to the program.

Bar height changes the exercise

Footbar height sets the starting hip and knee angle. Too high for your leg length and the start position is cramped; too low and you lose the range where the glutes contribute.

It is a fitting decision, not a preference. Set it for the person, and change it when the person changes.
