Swimmer's Snorkel Drills Jack Simon, Head Coach, State of Penang Swimming Association With freestyle snorkel and zoomers: 1. 2 x 50 kick, 1st one hands down at side, 2nd one arms in front streamlined. Follow the line on the bottom of the pool so that the center of the bottom curve of the snorkel stays online with the bottom. 2. Swim 50's until successful, keeping snorkel (head) lined up on the bottom line,no movement, would suggest 2 beat kick to start. After succesful, go to 4 beat and then onto 6 beat kick. Eventually build to all out 50 with snorkel with or without zoomers.
