I did manage to get myself to Crossfit at 06:00 this morning. After a warm up of air squats and skipping, we did a bit of yoga style stretching and then 20 max weight back squats (I used 50kg, but I should have had more on the bar really) then we did "Surfers on Acid" which is 3 rounds of run 400m and 21 burpees. It took me 11½ minutes which was OK for that time of day.
Then home, shower, breakfast and off to work for a loong day.
At least I only spend 1½ hours getting home tonight instead of the 2 hours it took yesterday.
