I cannot even begin to tell you how grateful I am to have recently discovered TI. I have been swimming recreationally most of my life and thought there was seriously something wrong with me because I could swim breastroke all day long but was completely exhausted after a single length of free. The few things I've learned so far about TI have already helped me make progress - beginning with recognizing that my kick only provides 5% of my propulsion therefore only deserves about that much of my effort and then moving my attention to my breathing. Thank you so much for your commitment to the principles of TI. I feel encouraged that progress IS possible!
