You mean the curly-haired dude? haha he was instantly hooked to bouldering!!! He's got good body features for climbing, methinks..thin, long, lightweight, and with big hands! =)

Bouldering is a style of climbing in which the climber does not use a harness or rope for protection from falling because the routes are below 25ft in height

• from rockclimbing.com.. I think bouldering is a subset of rock climbing. =)
