Overdoing it

I guess working out in the garden for an hour before yoga was too much because I could hardly get through today's session. I think part of the problem was I was dehydrated, even though I make sure I drank several extra glasses of water before I went outside. I finished all the water I brought to class (which usually doesn't happen) and drank two more glasses as soon as I got home. Or maybe turning 40 gallons of compost was more work than I thought.
