Are you looking to take your race day numbers to the next level? Then this one’s for you…

Last week Dean visited Gary Howells at Peak Performance Wales to carry out a physiological test which includes

💧 Sweat testing
💧 Fluid loss testing
🩸 Blood lactate testing

If you want to hydrate your body correctly, know the amount of sweat you’re losing & know your carbohydrates intake then lactic testing is for you.

A huge thanks to for keeping us fuelled correctly throughout the session.

We’re exciting to be working with Gary and offering this service now at D12 Gym 🔥
Drop us or Gary a message for more details

Congratulations Kevin Evans and everyone involved brilliant achievement 👏🥊

Hi everyone!

This year marks our 20th Anniversary Show, and we want to make it our biggest and most special event yet.

For over 20 years, Prizefighter ABC has proudly supported the young people of Carmarthen through boxing, strength and conditioning, dance, and fitness. We’ve helped develop confidence, discipline, and opportunities for so many in our community.

We’d love for you to come along and support our anniversary show. Your support will help ensure our boxing club can continue to provide these opportunities and keep doing great things for the people of Carmarthen for many years to come.

Thank you to everyone who has supported us over the last 20 years. We can’t wait to celebrate this milestone with you🥊🥊

🏆 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 🔥
