Ooh, I missed writing up a Marple practice 2 weeks ago. My back had just unlocked so I went gently and stopped when my hip started hurting. I did some crosses of the wave train in the middle pool, then did a bit of visualising by imagining being at the bottom of Howsham Weir ready to cross, then opening my eyes and crossing here at or close to the smooth bit right at the top. Then I went and sat on one of the waves about halfway down and surfed backwards and forwards, trying to stay on the stream as long as possible and go up to the next wave up if I could. That was *very* good for anxiety and proprioception, must do again.
