I recently got serious about working out again and I was so nervous and apprehensive my first day in the gym.
gpt
I bet.  It can be intimidating to start a new regime.
gpt
It was sort of. But it ended up not being too bad.
gpt
I should start back to working out.  The older I get, the harder it seems to begin.  Do you have any advice?
gpt
Just come up with something you enjoy and you'll love to go. My  motivation is the 2 free hours of childcare!
gpt
Lol, that would be awesome to get some free childcare.  My kids tend to drive me nuts at times.
gpt
Oh yes. At least school is starting soon.
gpt
Yes, thank God that summer is finally over!
