I took last Thursday off because I was exhausted after several good workouts that week. And I was going to hit it again on Friday. But then Friday got really busy, and when I finally got a chance to go to the gym I discovered I didn't have my shoes. It was the end of the day, and I gave myself a break (I was still pretty sore from some lifting on Wednesday too). But then I didn't do anything on Saturday or Sunday either. So I ended up going 4 days in a row without working out at all. I only count 3 of them as setbacks, but... it wasn't good.
Today I got back to the gym even though it was another busy day. I had about 20 minutes, max, and I made sure I filled 'em. 20 minutes of working out being better than nothing. Especially because I could have just continued the slide, what with the list of things I had to get done today. It's going to be hard for me to make my goal of 20 workouts now, but I feel good about today.
