A group of Ammanford fitness fanatics put their muscles to the test to raise funds for little Alfi Jay Morris, the one-year-old diagnosed with Neonatal Marfan Syndrome.
Members - and friends - of the Primal Gym in Dyffryn Road took part in a gruelling Caveman and Cavewoman Challenge and raised an impressive £519 to support Alfi.
All the money raised is being donated to a fund to build a multi-sensory room for the youngster.
Alfi's family plan to use Facebook to highlight his journey and show the difference people's donations have made to his life. They also aim to raise awareness of the rare genetic disorder.
Primal Gym's Paul Griffiths was delighted with the response of his members.
"I'd like to thank everyone who take part for a fantastic effort," said Paul.
Primal Gym plan to hold regular charity fundraisers with the next Caveman Challenge, in aid of Paul Pugh, set for October.
