Recruit max power in warming up and get better endurance

The more of your muscle fibers you use, the more blood you shoot in circulation. In general, when up to 20% of the muscle fibers are in use, the blood vessels are fully open meaning that you can more or less go on forever. When 50% or more of the fibers are used, the blood vessels are completely shut. In other words, as you get stronger, using smaller percentage of your fibers, the better your blood circulation gets, i.e. you get better endurance. If you have low maximum power, especially when it takes long time to recruit maximum power, you will get better endurance by including some maximum moves in your warming up. In practice, this can mean that instead of using 50% of your muscle fibers during a hard sequence doing your first hard route, you might only use 40% of them. This means that recruiting maximum power on warming up will ensure better blood circulation and thus better endurance. On the other hand, if you have high and fast maximum power, it might be that a very soft and relaxed warming up will get you better endurance. The reasons of it are that you will not overgrip on the easier sequences, which might hinder your blood circulation. Another way to improve your endurance, might be compressions sleeves, as in the picture.
