Age brings about a certain amount of isolation. This can make many seniors and baby boomers give up on fitness routines as they find it boring to do exercises on their own. Therefore, look for like-minded seniors to do the activities. Even something as simple as going for a walk in the evenings with your friends is exercise that will benefit your body a lot.
Even though you are a baby boomer, you still need to sweat out all the toxins. So, push yourself, but to a limit that you find comfortable. Make sure that when you are working out, you can still talk without being completely out of breath.
Most adults need motivation to do exercise or follow a fitness routine. It has been seen that many baby boomers actually benefit from having a pet like a dog. This way they will be forced to exercise the dog everyday or it for a walk and, in turn, they will get their quota of exercise without even thinking about it.
Above all, make sure that you see your fitness routine as something enjoyable. Do not think of it as a punishment or chore. You will then never want to do it. Try out activities that are fun and exciting to keep you yearning for more.
