At 121 gym we have some of the best personal trainers in South Wales.

Most of us work harder in the presence of others. Having a trainer by your side can provide the encouragement, energy and motivation you need to jumpstart your routine. A trainer can also help you set goals, create a plan to accomplish them and celebrate the day you reach them.

Whether it’s to lose weight, to build muscle, get fit or even train for an event like The Cardiff Half Marathon you need to be fit and ready RIGHT? Our expert team of specialist Personal Trainers (PTs) can help you achieve tour goals.
