Six burpees down and I could feel it coming back up. Only realised when chewing said piece of cake that it was less than 2 hours before my personal training session, but it was a damn fine slice of office birthday sponge, and it was worth it. Luckily I only did two thirds of my session as I bitched to Justin about my hamstrings and we had to stretch for 20 minutes. Note to self, might try that ruse again. He did tell me he was pleased with my progress and from next week he is intensifying the programme. I am genuinely flabbergasted that it could possibly be harder than this.
