Yes, I finally switched to cycling (and swimming laps).
I’ve discovered that doing a little, consistently really works for me. I don’t make it difficult — 15 minutes on the recumbent bike, 20 minutes of core exercises involving small hand weights (no sit-ups or crunches) every day without fail (including holidays) and 20 minutes of free weights on Mondays, Wednesdays and Fridays (dumbells, barbell on the weight bench) — has truly made a difference for me. I’ve lost 55 pounds in about nine months, and look better at 64 than I did at 46. Of course I have a weight bench and a bike down in the basement and actually have the time to put into it, and can skip the gym. I never had time for this while I was working full time and greatly sympathize with those who try to fit it in with their work schedules. It always daunted me.
