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.

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