At Family inHome Caregiving, we always encourage our clients to have good nutrition, plenty of social interaction and exercise to help them live a healthier and longer life.. Everyone is different, and not all seniors can tolerate a lot of exercise, but try the best that you can. One simple way is just walking more. There are all kinds of devices that can track how many steps you take each day, with 10,000 a goal. But start easy by walking around the block and you can work your way up to this. Walking at a constantly brisk rate can also get your heart rate up. According to the Centers for Disease Control and Prevention (CDC), to estimate your maximum age-related heart rate, subtract your age from 220 and this is the maximum beats per minute. The American College of Sports Medicine recommends for moderate-intensity physical activity at 64% to 76% of your maximum heart rate (Source CNN.com).
