INDIVIDUALISED COACHING
Fortis truly is for everyone who is serious about training. We meet you where you are and make the training appropriate for you via programme adjustments and exercise selection.
In our sessions, it's not uncommon to see athletes and coaches in the mix with absolute beginners, all working towards their own unique fitness goals.

Physical and psychological burnout within the fitness space is a common theme, but our members typically stay with us for years.

We've worked with everyone, from elite athletes to absolute beginners. Despite this, we have an insatiable hunger for knowledge, and as the science changes, so do we.

FAQS
Where are you based?
We’re based in Springtown, on the Balliniska Road.
When can I train?
See our timetable below. As we grow so does our timetable, but at the moment there's enough room for everyone (we have a membership cap) - CLICK Image to open.
What is small group personal training?
At FORTIS we split the difference between 1:1 training and larger group fitness classes, creating small groups of 6–8 people at a time led by an expert coach. This allows us to provide as much attention as you would experience in a personal training session but with a bit more fun and a lot more affordable.
I’m an absolute beginner. Can I join?
At FORTIS all fitness levels are welcome and absolute beginners are encouraged to join. After your initial assessment your programme is tailored to meet you where you are right now. Nobody is thrown in at the deep end.
I’ve been going to the gym for a while myself, is this too easy?
At FORTIS we have an eclectic mix of members. Since we opened our doors we’ve had professional and amateur athletes train alongside our beginners. We also routinely have strength & conditioning coaches and personal trainers join to sharpen their skills and give themselves another level of accountability. We take training seriously and if you do too, we’re probably the place for you.
I’ve got a sore back/knee/hip/ankle. Can I still join?
We mostly work with older professionals so aches, pains and niggles come with the territory. Our programmes can be manipulated so we can give you a training effect whilst avoiding unnecessary pain. We routinely see people regain range of motion and pain‑free movement at FORTIS. We also consult with local physiotherapists to give you the best tools to train around pain.
What if I miss a session?
We get it, life gets in the way sometimes. You’ll have adequate time to cancel via the app. However, if this becomes a regular occurrence after your trial, you’ll have a coach on your case to keep you accountable.
How long do I have to commit?
Once you've completed your initial 14 days, we offer packages ranging from a monthly recurring membership to 6‑month commitments (with discounts for longer‑term options). Whilst many people train with us for years, many choose a monthly recurring membership.
Do you offer an open gym?
We offer up to 20 sessions weekly at multiple times throughout the day; however, once your trial finishes if you can't make a session, you can use the gym during off‑peak hours to catch up.
