What kind of gentle exercise would be good for senior citizen who has joint pain?

Water Aerobics 
In recent years, water aerobics has become an increasingly popular exercise among people of all ages, but mainly among seniors. Exercising in the water is best for people who have arthritis, and other kinds of joint discomfort since the buoyancy of the water reduces the tension on your joints.

The following are some excellent water exercise activities for seniors: 
• Jogging in the water 
• Kicking flutter 
• Leg lifts 
• Push-ups while standing in water 
• Arm curls
