Same ol', same ol'

Continuing with the same ol' exercise and watching what I'm eating.  It's good, I think, that it feels like "same ol'" because it signifies that I'm developing useful habits of exercise and diet.  I--and more importantly my knees--are wondering if the same ol' may be creating problems for wear and tear on body parts.  So certain modifications are in order:  yoga one day a week with Lilias Folan; a rhythm and motion class as well; getting the bike ready to roll; and more attention to diet as helpful in keeping calories down.  Hopefully, these will allow different kinds of exercise and I'll start to identify what is problematic.  I'm considering the local gym, but I know I've never had good luck with getting myself over to machines unless I have a trainer waiting for me.  So much of this is knowing what works and doesn't work for me, even if it's great for someone else.  So it is same ol' same ol'--continuing to reflect on who I am, what motivates me, and what's good for me.  A life-long process?
