I've been going to the gym almost daily for the last few weeks. It varies on what I do there... Track, machines, weights, pool, I just rotate.
I'm not really enjoying it, though. I acknowledge its good for the kids(whether they're doing something active, or just in the child room playing with the other kids), but... I get so bored.
I think what would motivate me more is if I could take someone to exercise with me. Sometimes my oldest son will hang around, and working out with him is much more acceptable, but other times he doesn't come, or would rather be playing basketball with kids his age(reasonable). The solitude is often what is the most tedious to me. Getting over this hurdle is going to be my biggest challenge in sticking with it long term.
I think it would help if I could figure out a way to load books on my phone to listen to(its not a smartphone, no internet access). I can drag a book with me if I use the 'sit back' bikes(I don't know what they're called), but otherwise that isn't practical.
