In reply to JayPee630:
I frequently see Louis coaching bouldering at Vauxwall, all ranges of abilities from beginners to experts.
Whatever comes across in the Video, in real life his coaching seems calm, encouraging and helpful. Very modest and definitely not showing off ( Actually I'd love to see him do some of the moves in the Video!)
If you read advert carefully I think Louis is doing bouldering coaching but the climbing is being led others.
