Question

1. what is a key component of the warm - up phase in a fitness class?

deep breaths
static stretches
dynamic stretches
hydrate & reflect

1. why is it important to hydrate & reflect during the cool - down?

to prepare for the next workout
to increase muscle mass
to reduce heart rate
to replenish fluids and assess the workout

Explanation:

For question 7: Dynamic stretches are active movements that increase blood flow and range of motion, making them ideal for warm - up. Static stretches are better for cool - down. Deep breaths alone are not a key component of a comprehensive warm - up. "Hydrate & Reflect" is more relevant to cool - down.
For question 8: Hydrating replenishes fluids lost during exercise, and reflecting (assessing the workout) helps in future improvements. Preparing for the next workout is not the main purpose of cool - down hydration and reflection. Increasing muscle mass is related to exercise and nutrition, not cool - down hydration. Reducing heart rate is more about the physical cool - down exercises like light walking, not specifically hydration and reflection.

Answer:

1. C. Dynamic stretches
2. D. To replenish fluids and assess the workout
