['I recently got serious about working out again and I was so nervous and apprehensive my first day in the gym.', 'I bet.  It can be intimidating to start a new regime.', 'It was sort of. But it ended up not being too bad.']
I should start back to working out.  The older I get, the harder it seems to begin.  Do you have any advice?
