In multiple sclerosis, what is a typical weekly frequency for aerobic exercise?

• A. 1-2x/week
• B. 6-7x/week
• C. 3-5x/week
• D. 0x/week

Answer: (C)

Regular aerobic exercise for people with multiple sclerosis is generally prescribed several times per week to build endurance while balancing fatigue and heat sensitivity. The typical target is about three to five sessions per week. This frequency provides enough consistent stimulus to improve cardiovascular fitness and reduce MS-related fatigue, while allowing rest and recovery between days to prevent overexertion. Exercising only once or twice a week often doesn’t yield meaningful endurance gains, and pushing to daily or near-daily activity can increase fatigue, overheating, or symptom flare in many individuals with MS. So, several times per week—roughly three to five—best supports gains in endurance without overdoing it.
