What I've Learned
1 - The most difficult part is scheduling. I need to go to work, sleep, eat, and get chores done, so my leisure time is cut back.
2 - I was very, very sore the first week, but the second week was profoundly better. I am also sleeping very, very soundly.
3 - I need more equipment. I do not belong to a gym; my home gym needs an upgrade. I will have to get more equipment to work all of my muscle groups most effectively.
4 - My spouse is supportive, but with caveats. Waking up at 5:30AM disturbs her as she sleeps in until 6:30AM. I am working on being more sneaky.
5 - Slacking is easy. Looking at the weights, I could easily drop five or ten pounds and make my exercises easier. I don't, but I could.

What I've Changed
1 - I already ate good, but with the help of my wife I am eating better; more veggies and fruit, more protein, and bigger breakfasts. My wife is fantastic.
2 - I cut back on soda. When I open a new can, I dump out half immediately. I only drink a half-soda during the week, and one or two on the weekend.

I feel great and I want to continue to improve. I can just barely start to see improvement visually when I squint and stand in the right lighting. I'll continue to mark my progress and post images in the final week (Week 7, the completion of six weeks).
