Quick Definition: The phenomenon where a PUA seems out of spirit after many sets during a day, and then suddenly finds the strength and momentum to have a go at it again with renewed energy that seems like it is coming from nowhere.
Second wind is a phenomenon in distance running, as well as other sports, whereby an athlete who is too out of breath and tired to continue suddenly finds the strength to press on at top performance with less exertion. The feeling may be similar to that of a “runner’s high”, the most obvious difference being that the runner’s high occurs after the race is over. Some scientists believe the second wind to be a result of the body finding the proper balance of oxygen to counteract the buildup of lactic acid in the muscles. Others claim second winds are due to endorphin production, while still others believe it to be purely psychological.
We got a second wind after dinner and went out again in the marina
