Personally, as a “climber”,I prefer to try to climb harder and harder routes, so even as I get better, I’m still rising at a level where I’m getting pretty tired after an hour or two of bouldering.
But if your only goal is to avoid getting tired too fast, the keys to climbing forever without getting tired are:
1) Stick to more comfortable beginners’ routes (VB and V0 for now, maybe a little harder once you get better)
2) Understand how to maintain 3 points of contact in stable balance, so you can reach up from a secure, balanced position rather than swinging around like a clueless maniac and continually trying to fight the laws of physics with pure arm strength (This is probably an essential key on near-vertical walls)
Maintaining Balance Of A “Climber“
To maintain a balanced position, the first thing to remember is that when you take one limb off the wall, you ideally want the other three legs to form a stable triangle; either you’ll have one hand between your two feet or one foot between your two hands. If you have one hand way off to the side of both feet, you’ll probably swing away from the wall. If you have one footway off to the bottom of both hands, you’ll be putting yourself in an awkward position with a lot of weight on your hands and not much pressure on your foot.
Tam McTavish’s 5-second drill is a good suggestion for forcing yourself to find balanced positions that are easy to stay in for a long time. Just climbing a lot and noticing when you’re well stable or poorly steady will help you improve some, but having the discipline to force yourself to look for balanced positions actively will probably help you recover faster.
More To Know
The first key is to pay attention and TRY to stay close to the wall. For most beginners, it feels more natural to stand up straight and either bend their arms a lot or lean far away from the wall, but if you pay attention, you can force yourself to squat down into a position where you’re close to the fence, AND your arms are straight.
When you have your right shoulder into the wall, you can reach much higher with your right hand than with your left. When you have your left shoulder into the wall, you can achieve higher with your left hand. So, for example, if you’re starting with your right hand higher than your left, you should start with your right shoulder into the wall. Then, after you let go with your left hand and start reaching up, you should twist your left shoulder into the wall to reach for a hold higher than the one your right hand is on.
