These videos were created during the spring of 2020 when COVID cancelled practice. The team had other lessons published at the time, which is why that other training is mentioned.
Lesson 1: Improving body control (technique category 4) by working in a mirror face-on. You don’t need a mirror to learn from this, or to do it at home for extra progress away from the river.
Lesson 2: Improving body control by working in a mirror side-on.
Lesson 3: Belly breathing and abdominal/lumbar spine bracing.
Lesson 4: Thoracic spine bracing.
