I've blogged previously about Cal Newport's book Deep Work and how it relates to focused (swimming) practice. There's a new interview with Cal in The New York Times here

Check out Tim's interview with Terry in his new book 'Tribe of Mentors'

Want to see how Total Immersion compares to athletes like Cullen Jones and Michael Phelps? It's all about great balance and streamlining, whatever style you swim. Admittedly in the video below Phelps is swimming at 'easy pace' and not a 100m sprint, but for most adult swimmers we are nearly always training for longer distance and sustainable pace. This is where the efficiency of the Total Immersion technique really starts to count.
