Cardio

I did something to my lower back so I skipped the swings. On my right lower side I get intermittent mild pain and stiffness. Stretching helps. At first I thought it was the good morning, but now think I twisted it when I lost my balance trying to practice a new kettlebell drill. Foolishly I was in side on the wood floors so I had to rescue the weight when I lost my balance rather then just throw them to the ground. This is the only thing that makes sense. I will have to watch it closely.
5 Min Turkish Get-ups with 20kg KB. No problems with the back.
A very hard 20 min run. I am increasing my pace at the lower intervals.
Diet: could not have been a lot better today. I have really mastered eating sensibly. It does take a lot of work though.
