Which statement best describes the resistance training guidelines for targeting major muscle groups?

• A. Minimum of 2 non-consecutive days per week
• B. 8-12 reps for healthy adults
• C. 8-10 exercises should be performed to target major muscle groups
• D. 10-15 reps for older frail individuals

Answer: (C)

Focusing on major muscle groups means designing a routine that covers all the big areas of the body with a balanced set of exercises. Using about eight to ten different exercises in a full-body program is a practical way to ensure every major muscle group gets trained, including legs, back, chest, shoulders, and arms, while mixing multi‑joint compound moves with some targeted work. This approach provides broad coverage and efficient use of workout time, avoiding overemphasis on just a few muscles.

Other statements touch on how often you train or the specific rep ranges for particular populations, which are important considerations but don’t directly guarantee that all major muscle groups are being targeted in a single program.
