Question

jake is a powerlifter. which type of muscle does he mainly use during his workouts?
a) red muscles
b) white muscles
c) both types are used equally
d) neither are used during powerlifting

Explanation:

Powerlifting involves short - duration, high - intensity efforts. White muscles (fast - twitch muscle fibers) are better suited for such activities as they generate more force quickly, while red muscles (slow - twitch) are for endurance. So a powerlifter like Jake mainly uses white muscles.

Answer:

b) White muscles
