That's similar to what I'm doing now. The Daily 50 got me started, but I've set a goal that for every hour I'm sitting, whether it's reading, writing, or snuggling the pups, I will get up, put on the next song on my "New Found Goodness" playlist, and move my body.
At 75, and with fibromyalgia, I primarily work on stretches and balance at that time, leaving the strength for the Daily 50. Once that becomes easier, I'll add more strength somewhere in the middle of the day.
I'm much more likely to build this habit successfully, than to once again fail at the 'workout session' at the gym.
Thanks for taking the time to answer!
