It is indeed summer, and I am getting back into my exercise-at-Chatham routine. Yesterday was too hectic and I didn't get anything done, but I'm back to doing sun salutation yoga stretches and the 100 push-ups challenge. This year I'm doing all my push-ups from my knees. I will be able to do more push-ups and will be engaging my muscles for a longer period of time. For my initial test, which I did today, I did 23 knee push-ups. According to the push-up website I ought to start on week 3. I'm ok with that.
