The Double-Heel Plié exercise works your abs, butt, thighs and calves.
-We're gonna fold the band in half, create tension pulling apart, and bend both knees down. You're just gonna pulse the knees over the toes and hold slowly, lift the heels and little pulses, down, keeping that tension in the band. Let's drop 1 heel and pulse and switch heels. Drop the heel and extend.
