So you’ve heard the rumours and now you know it’s happening! Underground Gym has established itself as Brighton and Hove’s number one premier gym and is now opening a new site in Newhaven. We’ll be bringing you all the great equipment and classes that we are renowned for in Brighton but with some added extras… everything you could possibly want from a gym all under one roof. Classes include:

Combat
Calisthenics
Parkour
HIIT

We’ll have the best of the South coast’s physios on site plus a sauna to relax your well worked muscles. We’ve had a good few years to hone what we do in Brighton and you can tell from our member testimonials that we have got it right. We are ahead of the game when it comes to providing the best equipment but more than that we know that for our members an inspiring and inclusive atmosphere and an encouraging environment is what keeps them coming back and spurs them on to get the most out of their training. Underground Gym Newhaven is opening July 2017 and we have some amazing Early Bird offers https://www.underground-gym.com/newhaven. As with our Brighton gym, there is no contract tie in with our memberships. We’ll build the gym, together with our members we’ll create our fitness community, get in there quick and be a part of it from the start.

Which habit are we burying for good? 👀 Time to put a few of these gym habits six feet under! ⚰️👻

Going all in from day one, feeling bad for taking a rest day, or letting one number on the scales ruin your mood? We’ve got a few habits to lay to rest.

Training should challenge you, not leave you feeling like you need to make up for every meal or earn every day off. Learn as you go, find a pace you can stick with and give yourself a bit of breathing room.

Let’s leave these ones in the graveyard, shall we? 🪦

Ready to spin up a fright? 🎃🚴‍♀️

Karina’s bringing the Halloween vibes to Underground Newhaven on Thursday 29th October at 6:30pm, and you’re invited!

Grab your water bottle, bring a towel, and dig out your best scary costume. Let’s make this one a scream. 👻🖤

See you on the bikes, yeah?

One decent session and suddenly you’re looking for every excuse to show off those gains 😂💪 Let us have our moment, yeah? 👀

Tag your mate who’s always checking their arms after a session 😂

POV: You came in for a workout and somehow made a whole second life here 😂💛

The familiar faces, the chats between sets, the “one more set” that turns into another 20 minutes… suddenly, heading home is the hard part.

That’s Underground. Come for the training, stay for the people.

Your people might be here already. Come find out. 👊

Big goals demand more than good intentions. 👊

It’s the work you put in when motivation dips. The focus to keep your eyes on your own goals. The discipline to stay consistent, the dedication to keep learning and the determination to carry on when things get tough.

Talent might give you a starting point, but what you do with it is up to you.

How badly do you want the goal you’re working towards? Let that answer shape what you do next. 🖤

Ever wanted to nail your first pull-up, hold a handstand or finally master a bodyweight exercise you’ve been working towards?

That’s what makes calisthenics so rewarding. You build strength, control and coordination through bodyweight training, working towards new skills as you progress.

And you don’t need to be able to do it all before you walk through the door. Whether you’re learning the basics or ready to take things further, there’s a place for you in our calisthenics classes.

Ready to give it a go? Join us at Underground Newhaven and see what you can achieve. 👊

Three months from now, you could still be thinking about making a change… or you could be glad you finally started. 👊

You don’t need to overhaul your life overnight. Start with the things you can repeat:

→ Get your training sessions in.
→ Build a routine that fits your week.
→ Keep showing up, even when progress feels slow.

October, November, December. Three months of small actions that can take you closer to where you want to be.

Make a start today. Your future self will thank you.

You shouldn’t need to look a certain way, lift a certain weight or know exactly what you’re doing to feel like you belong in a gym.

At Underground Newhaven, you’ll find people at all stages of their training - different ages, different goals, different experience levels - all sharing the same space and getting on with their own thing.

That’s what stood out to Louisa when she joined us. She was nervous about joining a gym, but found a community where she felt genuinely welcomed by the staff and members. 🤝

Whether you’re here for the weights, the boxing ring, a spin class or simply to get yourself moving, you’ll find plenty to get stuck into.

If you’ve been putting off joining because you’re worried you won’t fit in, come and see us. Your first session is free. 👊

06/10/2026

The routine might feel repetitive. The results won’t. 👊

Same training days. Same early starts. Same decision to show up when you could’ve stayed home.

That’s the part nobody sees - the ordinary days quietly adding up to something different.

Because a year of doing the same things that keep you stuck will look very different from a year of consistently moving forward.

You don’t need to change everything overnight.

Just keep showing up.
