Bill Parisi on Instagram: "Split-squat ISO + oscillations. Barefoot. On the balls of the feet. This position exposes weaknesses instantly. The oscillatory isometric sends rapid micro signals through the fascia, hydrating the ground substance, strengthening connective tissue, and improving joint control. Going barefoot lights up the foot, ankle, and lower leg so the entire kinetic chain has to organize from the ground up. What can’t stabilize gets exposed. What gets exposed gets stronger."
