Teagan is showing her the stance. Her knees are bent. Her body torqued, ready to spring.
"You use your whole body." that's why she is effective against big muscle men most of the time. She uses everything and most of the time, untrained fighters think that all of the punch should come from the arm. Wrong.
"Think of your hips as you cocking your gun." she twists back at the hip, "Lean back slightly." this is all demonstrated.
"Good." Teagan praises, watching Maizie's posture carefully. There are a lot of steps she knows but each one makes the difference between a pussy punch and one that'll knock someone out.
"Now tuck your chin, take a breath, keep your fist loose." She is now in back of Maizie making adjustments to her line of her arms, to the way her hips are aligned with her feet.
"When you strike the bag, exhale, use your torso and your hips for power and tighten your fist right before you make contact."
