Introduction
Hi I’m Sam! I’m currently a head high school football coach and APC teacher. I played college football and majored in finance back in 2015. I spent 7 years as a financial planner and assistant football coach before making the career change into full time teaching and coaching - and it’s been awesome! Now the goal is to further accredit myself as a strength coach and develop the strength and conditioning program, especially with plans to upgrade the weight room facility and equipment in the near future. I’ve been self-studying the NSCA textbook but now I’m excited to be a part of this TEAM!

Biomechanics Conceps: Moment Arm
Moment Arm In the context of strength and conditioning, a moment arm explains why an exercise feels harder or easier at certain joint angles, because it determines how much torque the muscle must produce to move or control a load. It is tightly related to concepts of lever classes and, in part, helps to determine the sticking point of an exercise. Definition: The moment arm is the perpendicular distance between a force’s line of action and the axis of rotation at a joint. In resistance training: - It determines how much torque (rotational force) is produced at a joint. - A longer moment arm = more torque required from the muscle. - A shorter moment arm = less torque required. Example: During a biceps curl, the moment arm of the external load is greatest when the forearm is around 90° of elbow flexion, which is why the lift feels hardest there. Lock this concept in with your own training. When an exercise feels harder at certain joint angles or through a specific ROM, it’s likely because the moment arm is larger and the muscle has to produce more force. Question: Have you ever tried or prescribed targeted isometric or partial ROM work at the sticking point of a lift? For example, pause squats, pause at the knee deadlifts or cleans, spoto press, etc.?

Yes! Pause squats - definitely have helped the beginning lifters to lock in proper form (bracing!) and getting comfortable at full depth with a lighter weight before progressing heavier.
