Multiple sclerosis (MS) is an autoimmune disease that affects the central nervous system by damaging the myelin sheath surrounding nerves. Common symptoms of MS include fatigue, spasticity, heat intolerance, incoordination, and impaired balance. While exercise can help improve strength and fitness for those with MS, it is important they allow for adequate rest and recovery between workouts due to their fatigue and lack of coordination. Precautions must also be taken regarding environment since patients have low heat tolerance.
