Pulsating grip?

Hey everyone, I'm new to the 8a website and climbing in general. Could someone explain the pulsating grip? I've read it in several of the articles on this site but I wasn't able to find out what it is and how to use it. I have a vague idea but a nice description would be very much appreciated. Thanks in advance for helping out the new guy, Cory This is the main article that mentions this gripping technique. Any ideas. A pulsating or tickling gripping technique Based on the theory below, pumped forearms are the result of long constant contact time with the holds. One way of avoiding this is using a pulsating gripping technique. It helps liberate the muscle contraction to make blood supply possible, even for just a couple of short time windows. It means that all your body weight will have to be carried by only one hand at the time. The circulation in both your forearms is low when both your hands are used for holding on. Remember that the blood supply is completely shut when the muscle is at 50% of its maximum load. Most probably you are already unconsciously doing this as all top climbers are using it, but keep it in mind and develop your technique to make it more efficient.
