Bouldering is the ultimate exercise form for me: it's physically taxing, and I don't even care because my brain is enjoying the challenge too much! I can't commit to running, cycling or swimming because 30s in, I start to think about all the stuff I could be doing instead; when I'm bouldering, there's nothing else in my mind except for the problem :)

That's a shame, because cycling is absolutely incredible. Running or swimming? Eh, screw those.

I'd definitely enjoy cycling more if I didn't live in central London, which makes it more of a "death wish experience with lungfuls of toxic shit" than I'd like :)
