I work out late at night, and see the same other late-night exercisers at my gym over and over. It seems to be the norm, at ALL the fitness centers I've gone to, to NOT MAKE EYE CONTACT when one is exercising, and definitely to NOT TALK to other exercisers...like we're each in our own private bubble. But since there's such a small, regular group at Snap in the late hours, I've started saying HI to people, and smiling. Let's POP that antisocial bubble, and generate some community and support!
I always keep a little notepad and pen in my gym bag, not only to jot down how many minutes I spent on cardio equipment and what weights I did, but also whether I had any pain issues, found some exercise unusually difficult, discovered a cool new way to use the balance ball, etcetera. That helps me transfer stuff to SP later, because my memory isn't what it used to be! :)
Ask if you can receive a free gym membership through the Silver Sneakers program that comes with some health care programs for seniors. Programs may offer memberships at Ys, commercial gyms, or senior centers. Programs differ nationwide & consider you a "senior" at different ages.
