When I started I committed to ONE 10 minute walk and walked to the end of the block and gradually increased the intensity of that walk. didn't take too long. For me the important thing was just to move. Over time I upped the number of walks and the intensity of those walks until moving every day was something I just did.
Of course, you want to check with your doctor to be sure it is healthy to start exercising
Persistence is more important than perfection.
Don't assume your freedoms are assured.
If you're not outraged, you're not paying attention.
A good goal to aim for is 150 minutes of moderate exercise. That breaks into 5 30 minute sessions a week and should include cardio and strength. The 30 minute sessions can be broken into 10 minute sessions.
Maybe right now, you can only manage 5 minutes. Great! Next week add a minute or two. And so on and so forth.
Aim for whatever you can do. Add minutes as you are able.
