Exercise guide

Seated Single Leg Tibialis Press

  • Beginner
  • Isolation
  • Rep-based
  • Lower legs
  • Waist

This isolation exercise strengthens the tibialis anterior on the front of the shin, which is essential for ankle stability, knee health, and improving dorsiflexion. It helps balance lower leg development by targeting the antagonist to the calf muscles.

Muscles worked

Primary

  • Tibialis

Secondary

  • Hip flexors
  • Quadriceps

Equipment

  • Body weight

Setup

  1. Sit on the edge of a flat bench with your back straight and your core engaged.
  2. Extend one leg forward, keeping the knee straight or slightly bent, with only the heel resting on the floor.
  3. Place your non-working foot firmly on the ground to maintain balance and stability.

How to do it

  1. Pull your toes and the ball of your foot toward your shin as high as possible while keeping your heel anchored to the floor.
  2. Exhale as you reach the top of the movement, squeezing the muscle on the front of your shin for one second.
  3. Inhale as you slowly lower your foot back toward the floor under control, using a 2-second eccentric tempo.
  4. Complete the full set on one leg before switching to the other side.

Form checklist

  • Keep the heel of the working leg glued to the floor throughout the entire set.
  • Avoid moving the knee or hip; the movement should occur strictly at the ankle joint.
  • Ensure you reach a full range of motion, pulling the toes up as far as your mobility allows.
  • Maintain an upright posture without leaning back to compensate for the movement.

Pro tips

  • Focus on the mind-muscle connection by visualizing the muscle on the front of your shin shortening as you pull your toes up.
  • Pause and hold the peak contraction to increase time under tension, as this muscle responds well to high-intensity holds.

Make it harder

  • Place a light dumbbell or a resistance band over the top of the foot to add external load.
  • Perform the exercise with a slower 4-second eccentric phase to further challenge the muscle's endurance.
