About Us

Who are we?

Cerin Rees – the taller one. He’s Welsh, quieter, likes being silly on occasion and an extremely good coach. Known for his patience, motivation and creativity – ‘there is always a plan b’ and his other many catchphrases, such as,

‘Second time is always better’ and ‘Use it or lose it!’

He is (mostly) always right, particularly about all things exercise and activity and has an uncanny ability to encourage people to work just a little bit harder.

Anna Sheryn – the smaller one. She isn’t welsh, is (a lot) louder, also likes being silly and she too can coach a bit. Not known for her catchphrases (she steals Cerin’s) she is enthusiastic with a strong sense of fun and is likely to be laughing.
