Which muscle is the primary mover during a barbell back squat?
Answer: Gluteus maximus
The gluteus maximus is the primary mover during a squat because it drives hip extension from the bottom position.
What term describes movement of a limb away from the midline of the body?
Answer: Abduction
Abduction refers to moving a limb away from the body's midline, such as raising the arm out to the side.
Which plane of motion divides the body into front and back halves?

The frontal (coronal) plane divides the body into anterior and posterior halves and governs lateral movements.
The biceps brachii muscle crosses which two joints?
Answer: Elbow and shoulder
The biceps brachii is a two-joint muscle that crosses both the elbow and the glenohumeral (shoulder) joint.
During a push-up, the triceps brachii acts as which type of mover?
Answer: Agonist
The triceps brachii is the agonist (prime mover) during the pushing phase of a push-up because it produces elbow extension.
Which type of muscle contraction occurs when the muscle lengthens while under tension?
Answer: Eccentric
An eccentric contraction occurs when a muscle produces force while lengthening, such as lowering a weight under control.
