A Season Ticket!
That’s right if you want a tip for how to improve your climbing this winter, then I can’t recommend anything more than getting a season ticket to your local climbing wall. What it means is that say you finish work and you have a spare hour or so, then rather than think well its too short a time to head to the wall instead, you’ll be heading up there for half hours sessions just to get your money’s worth.
Of course that is if you live a reasonable distance from the climbing wall, and don’t have kids you need to feed, wash, and put to bed. If things are all in your favour then climbing little and often is a great way to improve. As several hour long session a week gives you enough time to warm up, and then do some form of intense work out before heading home in time for tea and medals.
It also stops you climbing/training to absolute failure as many climber force themselves to climb until they develop the kind of pump and fatigue where you struggle to get the keys into the ignition of the car and changing gear is an activity you need a co-pilot for. Generally though training for climbing shouldn’t be that so intense that doing your shoes up becomes a task in itself. If you do you’ll find yourself getting technically messy, lossing contact strength and often become more likely to injure yourself as a result.
