I have never been an athletic type. I lack coordination for many sports like tennis, volleyball, or baseball. I liked to play them but never was very good. I was picked last for any team. The older I got, the harder it gets to keep on moving. Any kind of moving that gets you off the couch is good. I wear a step counter, it helps motivate me. Do what works and NEVER GIVE UP.
I am past seventy and still fully functional. If I drift to the couch too long, I start feeling lousy, so I have to get up and get moving again. The MORE I move, the BETTER I feel. Don't even think, I may OVERDO it. Won't happen; never has. I get my couch time. The problem is being motivated to move and work enough, but it is worth it.
I am in my motivated state right now, and I hope it lasts. I do go to The Health and Fitness Group here on SC and post from time to time. I think that works for me, and I have friends in Shout who are gardening and walking and cleaning, and I it actually sounds like fun or a GREAT IDEA so I do MORE of the same.
I finally learned a little about motivation. You only have a limited quantity so realize that and work on finding fun and passion that get you up and out. If you don't have it, don't go it ALONE; find help from others. The years take a toll and the couch calls to you, but we have to fight back and it is worth it.
At my age, I am flexible and can do most anything. I am focusing on building muscles and strength. I lost too much of that. I don't love housework, but it is great exercise. I do like gardening, so I do that too. If I drift to the couch too long, I start FEELING LOUSY so I have to get up and get MOVING again. The more I move, the better I feel.That is the most motivating of all unless I forget it. Don't even think, I may overdo it. Won't happen; never has; if any part of me actually twinges or hurts, I stop and give it a rest. I have my failures and delays . Malaise, a little sniffle, a real issue like surgery and recovery or too many personal issues, will knock me right off my track.
I still eventually get up and get back to the track, to the work, to the gardening, to the volunteer work and to the gym or my exercise plan at home. Some movement can be done by almost anyone. Just call it physical or occupational therapy that you do for yourself.
