In the gym

I've started gym training last week. It's related to my research but also out of personal interest to become better in volleyball (my goal is to jump higher than Mika, my 2.05cm tall colleague :). It's much more fun than I thought (thanks to my trainer Peter), but it's also far more difficult than I had assumed.
Anyway, my colleagues suggested that I should use myself as a case study and take a picture each day to track the progress. Not sure if that's a good idea :)
