Exercise guide

Sitting Floor Tibialis Raise

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

This isolation exercise targets the tibialis anterior on the front of the lower leg, which is essential for ankle stability, knee health, and balancing the strength of the posterior calves. By keeping the leg straight, you also engage the quadriceps isometrically to maintain knee extension.

Muscles worked

Primary

  • Tibialis

Secondary

  • Hip flexors
  • Quadriceps

Equipment

  • Body weight

Setup

  1. Sit on the edge of a flat bench with one leg extended straight out in front of you and the other foot flat on the floor for support.
  2. Position the heel of your working leg on the floor with your toes pointing forward and your knee fully locked.
  3. Sit tall with your shoulders back and place your hands on the bench beside your hips for stability.

How to do it

  1. Pull your toes toward your shin as high as possible (dorsiflexion) while keeping your heel firmly anchored to the floor.
  2. Exhale as you reach the peak contraction and hold for one second to feel the burn in the front of your shin.
  3. Inhale as you slowly lower your toes back toward the floor, maintaining a controlled 2-second tempo on the way down.
  4. Complete the desired number of repetitions on one leg before switching to the other side.

Form checklist

  • Keep the working leg completely straight to ensure the quadriceps stay engaged and the tibialis is isolated.
  • Maintain heel contact with the floor throughout the entire movement.
  • Avoid 'bouncing' at the bottom; use a slow, deliberate motion to move the foot.
  • Ensure the movement comes strictly from the ankle joint without rotating the hip.

Pro tips

  • Focus on the mind-muscle connection by imagining you are trying to touch your toes to your kneecap.
  • Pause for a full second at the bottom of the movement to stretch the muscle before the next contraction.

Make it harder

  • Loop a resistance band around the top of your foot and anchor it to a point in front of you to add tension.
  • Perform the exercise with your heel elevated on a small weight plate to increase the range of motion into plantarflexion.
