How many days per week should adults perform resistance exercises for each major muscle group?

• A. 1 day per week
• B. 2-3 days per week
• C. 4-5 days per week
• D. 6-7 days per week

Answer: (B)

The idea being tested is how often adults should train each major muscle group to build strength and muscle effectively. Training each major muscle group on multiple days per week provides enough ongoing stimulus for growth while giving the body time to recover between sessions. Spreading the workload across several days helps you accumulate a solid training volume without overloading a single session, which supports steady progress and reduces fatigue that could hamper performance. This frequency fits a variety of practical schedules—full-body workouts done on multiple nonconsecutive days, or split routines arranged so that all major muscle groups are worked regularly across the week. Training the same muscles every day can outpace recovery and blunt gains unless volume and intensity are very carefully managed, and focusing on just one workout per week usually leads to slower improvement because the weekly stimulus is too low. So, the best approach for most adults is to target each major muscle group more than once per week, balancing workload with adequate rest.
