🏆 Congratulations Holly🏆

Another superb achievement from one of our long standing members Holly Walters. Over the last few months she's been putting the work in behind the scenes and has, as a huge result, managed to achieve 1st Female in the 10 Y Fan challenge. 10 trips up and down Pen Y Fan, through the night, over a 24 hour period. INCREDIBLE 🏆🏆

The pride we have in our members is second to none, we strive to be the best around to allow all of our members to have every tool required in our gym to achieve whatever goal they're chasing.

From gym refurbs, to the BOCS, funkypump, Hyrox, kids Hyrox to power lifting let's just say.... We're not done yet

What can we say, but thank you and congratulations to each and every athlete from D12 that took part in Hyrox Cardiff. Almost 50 athletes from our unreal community ran the gauntlet and put on some phenomenal times. We started 14 years ago as a humble, independent gym in Carmarthen with nothing but drive, ambition and dreams to build the best community we can.
This is some team we have and the one thing we can guarantee...the best is yet to come 🔥
