when working out with a goal of general muscle strength, not power lifting, how many seconds should you rest in between sets?
30-60 seconds
60-90 seconds
90-120 seconds
8 multiple choice 1 point
after working out a certain muscle group, how many hours of rest should you have before doing another workout focusing on that muscle group?
12-24 hours
24-48 hours
36-48 hours
48-72 hours

Explanation:

1. For the true/false question: Consistent strength training increases muscle fiber size (hypertrophy) but does not create new muscle fibers in most adults; muscle growth comes from existing fibers enlarging, not increasing their number.
2. For question 7: For general muscle strength (non-power lifting), rest periods between sets are typically 60-90 seconds to allow partial recovery while maintaining metabolic stress for strength gains.
3. For question 8: Muscles need 48-72 hours of rest after targeted training to repair and grow, as muscle protein synthesis peaks and repairs micro-tears in this window.

Answer:

1. False
2. 60-90 seconds
3. 48-72 hours
