I know I won’t word this correctly so be patient. I actually know very little about swimming other than I put a lot of time into it.
On your catch where should your hand be in relation to the side of your body? If your elbow is high and somewhat parallel to the surface with forearm perpindicular (90 degrees) to upper arm this would place your hand the length of your upper arm away from your torso during the catch. Is this correct or should the hand be closer to the torso during the catch?
