To swim your fastest, one thing you always have to keep in mind is how FAR you swim. Swimming straight in a race means you're swimming the shortest route possible to the finish.
Why Do It:
Bad habits can form in practice without the swimmers really being at fault. Being aware of what's happening can help you control your own destiny.
How to Do It:
1. When you're swimming in a crowded lane, chances are you're biggest job on a turn is to avoid the other swimmers.
2. Most swimmers approach the wall directly, and then, as they exit the wall, they veer out of the way of the swimmer behind them. This builds the habit of always pushing off at an angle and can lead to circle swimming in races.
3. If you can, when the swimmer in front of you pushes off, try to get your feet on the cross to limit the push angle.
4. The best solution is to veer across the lane prior to your turn so that you can practice a straight push off each time.
How to Do It Really Well (the Fine Points):
Teach your lanemates how to approach and leave the walls with more thought. Working as a team in developing better technique can lead to higher success rates for everyone.
