Explanation:

• Question 10: Free - weight workouts use external resistance like dumbbells, barbells, or kettlebells. Body - weight workouts use only body weight. Powerlifting is a type of strength sport. Resistance - band workouts use elastic bands.
• Question 11: Cortisol is a stress - related hormone. Endorphins are "feel - good" hormones. Serotonin is related to mood. Norepinephrine is involved in the body's stress response but in a different way than cortisol.
• Question 12: For strength and muscle growth, a rest interval of 2 - 3 minutes between sets is recommended. 30 seconds is too short for full recovery for strength gains. 1 - 2 minutes is more for hypertrophy (muscle growth but less for maximal strength). 3 - 5 minutes is more for powerlifting or maximal strength exercises where more complete recovery is needed for heavier lifts.

Answer:

• Question 10: D. Free weight workouts
• Question 11: B. Cortisol
• Question 12: C. 2 - 3 minutes
