Resisted great toe flexion in sitting for intrinsic strength (Hallux big toe extension strengthening, with band, sitting)

Sit up straight in a chair with a resistance band looped around your big toe.
Hold the other ends of the band in both hands.
Keeping your other toes firmly on the floor, raise your big toe.
Push your big toe back down towards the floor against the resistance of the band.
Continue to repeat this movement, ensuring your other toes remain on the floor.
