This is a documentation of day 23 of 39 (I update the morning after a day is complete)Tuesday, May 23, 2017 - Day 23Aikido in the evening and burned 579 calories. After having stem cells injected into my knees, my knees hurt at about 6 on the pain scale. We also did an interesting exercise to gauge fitness on the mat specifically for Aikido. 1 repetition was attack, get a technique applied to you and then fall. The idea was to do that 8 times in 30 seconds or less, I did it in 32 seconds. Cool concept but out of my wheelhouse - at my skill level that feels way too high risk to do again. I have to safely get my 50 year old, 6' 2", 215 pound body 12' round trip on every fall - too many things can go wrong if I push hard enough to make the time standard. Yet another example of my thought process change as I age. Definitely getting wiser - young Z would dive in first and then figure it out on the way. Older Z is rarely where he is, most of the time he's in "...if I do this now, how will my body feel 5 years from now..." mode. I liked the push into my discomfort zone though. My body is very sore - my legs are KILLING me - like after having done AT intervals on the bike.I had 5 meals each in the 480 calorie range.For the day I burned 3,039 calories.I took in 2,454 calories.The net deficit was 585 calories.I slept 7:50 In my own bed and took Sleep Works and it was 4:04 of deep sleep!I drank 105 oz of water.Bottom line - Today was a win. Because I'm alive and can move.For those who asked...yes I still have a training dairy and yes you can still see it. It's here and I usually update it every few days.
