Simple stretches and strength training. Try using canned goods as light weights.
Tai chi. Find a DVD and try it at home. It helps with balance as well as providing exercise.
Walks. Just going around the yard is fine. Early in the disease, walking in a mall might not be too disorienting. Stick together if you head out into crowds or beyond a fenced area.
Gardening. Simply pulling weeds can be a satisfying source of exercise.
Water exercise. Check local Y’s or senior centers and ask if you can take classes together.
Household chores. Try hanging laundry, dusting, washing the car.
Stationary bike. If you don’t have one at home, try one at the gym or senior center.
Exercise class. Some senior centers and facilities offer classes specifically for people with dementia.
