AHA! Every so often on the Meadows (a big park in the centre of Edinburgh) I see people doing this with someone shouting at them! I assumed it was OTC but that makes sense...
It looks really good from what I saw, though. Go you! I'm definitely not fit enough, but I will be soon hopefully Good luck!
I saw a group of people doing this the other day, I was totally confused until I remembered I saw it!
Personally, it's too extreme for me to be able to keep up, but I can see it does help people and I would love to have a go at it myself for a short term. Looks quite fun actually!
haha, well apparently they have a group for beginners, intermediate and advanced so I don't think you need to be all that strong, just willing. I've always been attracted to the military side of training and although I'm not really that strong or fit I think it'd be fun to at least try out.
