Kawahara: Because Justin’s feet are supported, he’s working shoulder stability in addition to his core. With the knee tuck, we’re really trying to engage his lower abs and work his hip flexors. We want him to squeeze and pause at the top, then slowly control his legs back, which really overloads the core and develops good strength.
