and Weight Transfer

Balance
Definition:• Ability to stay in a point of
nothingness with no outward tension
Examples:• Defensive stance• Medicine ball push ups.

Pictures of Balance
• Erectors, quads, and abs are used for balance

Follow Through
Definition:• The completion of a form of
movement that results in relaxationExamples:• Golf club ends up over the shoulder• Tennis racquet ends up past the
body

Images of Follow Through
• Muscles used (in golf) include quadriceps, hamstrings, abductors, adductors, obliques, gluteus maximus, latissimus dorsi, trapezius, pectorals, deltoids, triceps and biceps. That’s a LOT of muscles!

Leverage (Levers)
Definitions:• The exertion of force by means
of a lever• A device you apply force toExample:• Bicep curl

Pictures of Leverage
• In torque, muscles act as effort forces to move loads.

Torque
Definition:• A twisting force that often
causes rotationExample:• Twisting Oblique Crunch

Pictures of Torque
• Trapezius, deltoids, abdominals, pectorals, and Latissimus Dorsi are used in torque.

Weight Transfer
Definition:• Stepping power• The ability to shift weight from
one point to another. Example:• Throwing

Pictures of Weight Transfer
• Weight transfer works with the quadriceps, latissimus dorsi, and trapezius.
