While still studying I never needed to become a weekend warrior. Well, things dramatically changed after entering a proper job. Since the week is always packed with work there is hardly any time to train, let alone climbing. One has to use every second of the weekend in order to stay in shape and log some miles in.
A great example of what can be achieved on a single weekend [with adequate preparation] is shown in the following video by David Burdick, John Frieh and Zac West. Enjoy.
