Freediving is usually done underwater, so frog kick and butterfly stroke are mostly used.
Orty explained the differences between the two swimming styles, and Luke chose the more professional and energy-efficient butterfly stroke, although it might be a bit more difficult to learn at first.
There were also some key points about breath-holding, which Orty detailed. With the help of the Diving Card, Luke learned quite quickly.
After practicing separately for a while, Luke began his formal attempt at freediving.
Luke dove into the water with a splash and disappeared from sight, leaving only a shadow visible underwater. When he came up again, he had reached the other end of the pool.
"Clap clap…"
Orty couldn't help but applaud, her chest bouncing in the process, "Wow… you swim really well. Have you never learned freediving before?"
"Thank you for the compliment, I just encountered a good coach is all."
