Pelvic bone Femur Anatomy and Kinesiology of the Pelvic Girdle

Lesson Plan: 44a Anatomy and Kinesiology of the Pelvic Girdle • 5 minutes: Breath of Arrival and Attendance • 10 minutes: New Muscles: • Iliopsoas • Sartorius • Adductors • Deep lateral rotators • 20 minutes: Iliofemoral and Tibiofemoral Agonists • 20 minutes: Reviews of muscles to be sculpted

Classroom Rules Punctuality- everybody's time is precious: • Be ready to learn by the start of class, we'll have you out of here on time • Tardiness: arriving late, late return after breaks, leaving early The following are not allowed: • Bare feet • Side talking • Lying down • Inappropriate clothing • Food or drink except water • Phones in classrooms, clinic or bathrooms You will receive one verbal warning, then you'll have to leave the room.
