Question

which muscle is the prime mover during a bench press?
a. biceps brachii
b. latissimus dorsi
c. pectoralis major
d. trapezius
what is the primary purpose of keeping a neutral spine during resistance training?
a. to increase resistance
b. to prevent injury and maintain proper form
c. to build more muscle mass
d. to burn more calories
which plane of motion does a biceps curl primarily occur in?
a. frontal plane
b. transverse plane
c. sagittal plane
d. coronal plane

Explanation:

• For the first question, during a bench press, the pectoralis major is the main muscle responsible for the movement.
• For the second question, keeping a neutral spine during resistance training is to prevent injury and maintain proper form as it helps in distributing forces evenly and avoiding strain on the back.
• For the third question, a biceps curl primarily occurs in the sagittal plane which divides the body into left and right parts and movements in this plane involve forward - backward or flexion - extension.

Answer:

1. C. Pectoralis major
2. B. To prevent injury and maintain proper form
3. C. Sagittal plane
