SUP yoga: The practice of yoga on a paddleboard
Yoga requires focus, stamina and patience.

SUP yoga - or stand up paddleboard yoga - involves most of the usual yoga positions, but with the added complication of it being done at sea on a paddleboard.
Jen Austin runs a yoga school in Newquay and teaches the practice when tide and weather allow.
