noun - Deck-up (or Pull-out or Pull-up or Get-out) is a pool training methodology whereby open water swimmers or triathletes pull themselves out of the pool after each swim and then dive back into the water for the next swim during an interval-training set. The methodology prepares the athletes for the end of an open water race with an onshore finish or a T1 transition in a triathlon. It is one element of the concept of interleaving in the training of open water swimmers and triathletes.
The coach asked the swimmers to do a set of 10 deck-ups where they pulled themselves out of the pool and dove back into the water for 10 fifty-yard sprints on one minute.
