What you get with us...

Getting in shape can really seem like a battle. Underground Fitness is here to turn that battle into a fun and steady process, as we gradually build up your training ability in our group workoutsl, led by our well-known friendly and knowledgeable coaches. We always keep our workouts fun and challenging (despite being meticulously programmed by our coaches), replacing the chore of working out with the thrill of the session. Everyone has their own full workstation and equipment, so you go at your own pace, fully coached all the way through. The goal is to make 3 workouts a week, picked from over 70 held weekly. It’s that easy. 

Take your training to the next level with our experienced Personal Trainer led Semi-Private Groups. Your goal is to make 3 of our fully programmed workouts a week, all going at your pace, using your own rack and equipment. It’s that simple. The workouts are different every, so its always a fun and challenging experience. We take care of all the meticulous programming in the background. Book in using our app and you will have full access to all class times (pick from 70 weekly), including free kickboxing and yoga classes you can attend too. There really is no other service who offers the same level of flexibilty (perfect for busy people).

As part of our 6 week challenge assess you on our private scanner, supply you with a 50 page nutrition guide and meal plan, and continue to assess your progress making sure you reach your goals (but ofcourse you can always just attend to workout). You can start with us in a week trial, then choose to take part in our 6 Week Program after. After the our membership is just 145/month, zero contract. We only have space for 250 individuals in our system, so if we have space, come join us.

Very professional, well organised and lots of check ins on your goals. 50 min classes are the right amount of time and plenty classes to choose from.

Excellent gym - small class format personal training, exercise tailored for the week to target different areas and for recovery. Well maintained equipment and a lot of it to keep you on your feet, the PT’s change up the exercises regularly so you’re not bored and keep the exercises dynamic. PT’s know their stuff, keep you motivated throughout the class, and keep a great atmosphere going throughout the class too. Paddy keeps in contact with you re diet and body comp analysis so that you’re kept on track, really great personal touch. Simple booking of classes through the app, handy for keeping with your personal schedule. I haven’t availed of it but there’s bonus yoga and kickboxing classes too. Would highly recommend!

Really enjoying the classes so far! What stands out for me is how I'm several weeks in and still amazed at how each instructor incorporates new exercises for different muscle sets all the time. No two classes have been the exact same. Great job!

The personal trainers are all brilliant and so friendly! Every class is different so it keeps you motivated and every area of your body gets targeted with stretching included. The support behind the scenes is very helpful too and you are given a choice of the level of involvement you would like in regards to achieving your goals. I am thoroughly enjoying my experience with UF and highly recommend it if you are looking to get fit/strengthen/feel good without any pressure.

Only four weeks at Underground Fitness but find it a great place to train with huge variety in sessions to keep it both interesting and challenging... Coaches are great throughout the sessions and to have regular touch points to make sure progress is being made, and the UF App is simple to use for booking in sessions.
