SES is recommended for those who are new to TI, but can swim at least 50 yards of crawl stroke or those who have been self-coaching in TI methods and would like to be evaluated and corrected by TI Coaches. In SES, you'll gain the ability to swim with greater ease and enjoyment by learning the essential efficiency foundations of Balance, Streamlining and Effective Propulsion. SES will include 75% Drill and 25% Whole Stroke and will be drawn from Lessons 1,2, 3, 4, 6 and 7 of the TI Perpetual Motion Freestyle sequence. Balance. Learn to be comfortable and relaxed by cooperating with - rather than fighting - gravity. Balance creates the body control and sense of mental calm needed to learn every subsequent skill. It also allows you to choose your stroke rate, which is the swimming equivalent of being able to take a jogging or walking breather during a long run. This lets you swim farther without fatigue. Streamlining. There are two forms of Streamlining. In Passive Streamlining, you shape your body to be longer, sleeker, more hydrodynamic. In Active Streamlining, you stroke in ways that move your body forward, rather than moving the water around. Your greatest energy savings – and greatest increases in both endurance and speed — come from Streamlining. Effective Propulsion. In the SES class our propulsion emphasis will be mainly on directing ‘available’ forces, rather than generating muscular forces. Learn to maximize use of naturally-occurring forces, particularly the combination of gravity and body mass, to minimize reliance on muscular force. Because available forces are ‘free’ this reduces energy cost.
