Bi-lateral breathing (BLB) is a great tool to have in your bag of tricks. I have been swimming to one side my whole life and I figure it’s time to change that. And I want all of my athletes to learn to swim bi-laterally too.
There are a lot of good swimmers out there. However, even good swimmers sometimes don’t know how to get faster and/or how fast they should be swimming. Which is why it can be helpful to know your Cruise Interval.
