Smoke as much as you want, drink as much coffee as you can stomach but NEVER go to Boot Camp if you haven't eaten for 15 hours.
A 40 pence banana at the Hampstead Heath Cafe five minutes before class is better than nothing, I'll vouch for that.
The class was extraordinarily difficult for me despite being no different to past weeks.
The Master's a good teacher though.
I'm glad I forced myself to go.
