Backstroke Recover and Catch
During the recovery, you can see how Ash nearly hyperextends his side, reaching for the highest recovery point. This shift in his torso adds power to the pull of the other arm, and he's very careful that as he engages his side, the recovering arm does NOT over-reach upon entry.
You can also see the subtle hesitation when he reaches extension on entry. Head position remains, as always, absolutely solid.
