Just start with a morning walk. When COVID began I went a month without working out with my trainer. Over two years I felt better, lost inches, but no weight to speak of.
After that month I decided to get up and walk. Left the house at 5.30 am and when I got back I figured I had done about 5 miles...looked at meter and that shit said 2.2 miles. LOL.
I marked off a 4.0 mile track and got busy...three times a week. lost about 5 pounds. The wife decided to begin walking with me. With a partner my consistency got perfect, but her little feet be moving like a muthafucka...I went from 15 minute miles to 14 minute miles.....I know for you real runners that is laughable, but it is a start........got to where I began jogging in front of her and let her catch up and then jog and let her catch up, etc.
In a month of that I dropped another 10 pounds. BUT I have also really, really, really watched my carbs. Sugar has never been a problem, but carbs have been.
Anyway I said all that so say this, just start walking and go from there.
