The subject of this thread made me laugh. In the past, I have usually recovered from a new exercise regimen in just a few days. On day 1, I'd be all gung ho and excited. On day 2, I'd be sore and why-ny ("Whyyyyy do I hafta doooo this?"). By day 3, I'd typically be substituting food treats for exercise. ("Ummm... I ran two miles, well, okay, I walked but I was walking fast and I KNOW it was at least a mile and a half, well... okay, a mile, so how much peanut butter can I afford?") By day 4, I'd be recovered and back to official couch potato status.
Since I've been doing the month-long challenges and posting my workouts in the exercise forum, however, I really seem to have succumbed. It looks like maybe I won't recover at all this time. I've been going 51 days straight now (March 31 - May 20 - and I turned 51 yo during that period, on April 28). Most of what I've read about habits says it takes 21 to 42 days to establish a habit, so I guess I have a real, honest-to-goodness exercise habit now. I'm so embarrassed...
For real, I can relate to ramping things up too fast. I've done that plenty of times. Stay on track. Dial the intensity back as much as you need to and keep on trucking.
