Feel Your Inner Thigh Muscles; Butterfly Over Stretch with Groin Contraction; 縮陰蝴蝶式

When I do 'Over the Butterfly', I contract my groin muscles to find their connection with the lower back and the core. The connection creates the strength to lift and isolate your torso from the hips. Contracting my groin muscles protects my knees and allows me to feel the intense stretch in my inner thighs and hamstrings.
