Sunday Swim Class #3 (17 Jan 2016)

Class Size: 4

No Time Trials

Observed common issues:
  • Inconsistent stroke count per lap
  • Overly wide kicks
  • Over rotation
  • Limited propulsion per stroke
  • Unable to catch up with slightly faster tempo on tempo trainer

Key focus: Reduce kick size to increase propulsion
Worked on:
  • Changed Reference point for tempo trainer to arm extension:
    • Slows down the state of mind
    • Increases the time spent in skating position - increase glide/stroke length
  • Delayed 2 beat kick:
    • Using the kick to amplify 0-45 instead of initiating 45-0
    • Feeling the natural fall initiated by recovery arm instead of using kick to force the rotation
    • Synchronized to water insertion point at mid forearm
  • Overly wide kicks:
    • Intro 6 beat kick timing with tempo trainer
    • Intro 2 beat kick with no body rotation
    • Scrunched toes 2 beat kick (locks hamstring) - smaller kick
  • Over rotation:
    • Demo difference between normal rotation and reduced rotation
    • Need to reduce rotation angle to cope with higher tempo
    • Reduced rotation angle reduces the need for a stronger kick - students kick much lesser.

Sunday Swim Class #2 (10 Jan 2016)

Class size: 5

Completed 180m Time Trial

Observed common issues:
  • lack of understanding on how to complete a TT:
    • taking too long to turn at the walls
    • inconsistent focus
  • Crossover during breathing
  • Head tilting up during breathing
  • Over rotation

Key focus: Lateral balance
Worked on:
  • Ideal head position in water during breathing - pressing top of head down
  • Deliberate pushing of leading hand outwards during breathing to reduce crossover
  • Correction of leading hand position with aid of visual feedback during skating
  • Over rotation - belly button pointing just outside of lane marking
