Add the following to every swim:
• Kick set: hand-lead, on your back, butterfly kick or freestyle kick, no kick board, no fins*
• Head-lead rotation drill
• One-arm butterfly drill
• Some breaststroke
• Breaststroke with a butterfly kick
This is the most effective way to increase your core strength.

Increased core strength benefits everything you do, from standing and walking to golf and tennis, everything.
