Done the handstand obstacle course yersterday- neck is very tight today.
Also attempted the crab thing. It's so tough I couldn't even manage one breath with a single limb up in the air. After many many many attempts I simply went with 5 sets of 7-breath crabs. I wpuld hurt you Euan..... if I was able

Plan on doing the climb ups and head stands when I go back home on Thurs/Fri and the rail balance whenever I find the time (maybe Sat)
EDIT: was a little disappointed at not getting the crab stuff so went back and tried it again. Think doing it at the flat on a smooth surface made it more difficult but I managed to get my legs off the floor and straight up in the air.... with a great deal of practice! Still can't manage to lift up either of my hands though!
