@Otis, get back on the rower! Is there a goal you can set? Motivation toward a goal is always easier. Is running still off the table? Set a goal for a 5K? 10K? Half?
Getting up to a 40" waist is what was the tipping point for me 10 years ago. Now I'm down to 32". And fear of getting back to that 40" (or having to buy new work clothes) is a great motivator to keep at it.
Tack-on Strava, running with RL friends, and the best iFriends (10K thread) in the universe, and forming good habits is not that hard.
And stop drinking your calories. No faster way to flush your efforts down the drain. A thousand times, this. How about a no-booze week? Month? See how it goes?
