Short instructions

How to do Leg Extension

Follow the numbered positions in the image and use each instruction as its matching cue.

  1. 1

    Set the starting position

    Adjust the machine so the knee aligns with its pivot, place the pad above the ankles, sit back fully, and grip the handles.

    Breathing: Breathe steadily; do not hold your breath.

  2. 2

    Perform the effort phase

    Exhale and extend the knees smoothly while the thighs and pelvis remain against the seat.

    Breathing: Exhale through the effort.

  3. 3

    Control the end position

    Stop just short of forceful knee lockout and hold the quadriceps contraction without lifting the hips.

    Breathing: Breathe steadily; do not hold your breath.

  4. 4

    Return under control

    Inhale and bend the knees slowly until the starting angle returns without letting the weight stack crash.

    Breathing: Inhale through the controlled return.

Setup and safety note: Use the declared Leg Extension setup, maintain controlled joint alignment, and stop if the movement causes pain.
