We’ve just wrapped up an incredible Seaside Fitness Series… but we’re not slowing down 👀
Next up: our in-house event sponsored by Athletics 🔥
On the same day, we’re also running an “Outside the Box” social — heading over to The Dolphin, Cleethorpes for interactive darts, bar games, and a chance for the whole community to get involved 🍻🎯
👉 This part is open to everyone — members, friends, and anyone who wants to be part of the day.
I’ll be setting up the event on Streamfit shortly so you can register. Let’s get as many of you involved as possible for the main event 💪
Workout Details:
For Time:
• 10 Shuttle Runs (25’ down + 25’ back = 1)
• 50 Wall Balls (9/6kg) (10’/9’)
• 10 Shuttle Runs
• 50/40 Cal Ski (or any machine)
⏱ 10-minute time cap (scale as needed)
🏆 Prizes from R.A.D®:
• 1 pair of trainers for top male
• 1 pair for top female
• 1 BONUS pair for our MVP of the day — effort, attitude, and energy matter
Let’s make this a big one. Compete, support, and then celebrate together 🙌

SEASIDE FITNESS SERIES WAS A BLAST
Alright… we’re going to say it straight 😅
We really need your help.
Seaside is coming up and we’re short on judges/volunteers — and without you guys, the day just doesn’t run the way it should.
If you’ve ever been to one of our events, you know how good the atmosphere is… this is your chance to be right in the middle of it and help make it happen 👊
We’ll look after you:
☕ Coffee sorted
🍔 Food provided
🙌 Good vibes all day
No experience needed — we’ll brief you on everything.
If you can give a few hours (or the day), it would make a massive difference to us and the athletes competing.
Drop us a message or grab one of the coaches — we’d really appreciate it ❤️

So you think CrossFit is too difficult?
Let’s clear something up…
CrossFit isn’t about being the fittest person in the room. It’s about becoming a fitter version of you.
Every workout is scalable. That means whether you’re brand new to exercise, coming back after years off, or already in great shape — it’s designed to meet you where you are.
Can’t do pull-ups yet? No problem.
Never lifted weights before? We’ll teach you.
Worried you won’t keep up? You’re not supposed to — you go at your pace.
What is difficult is staying stuck where you are.
What is hard is not feeling confident in your own body.
CrossFit isn’t about perfection — it’s about progress.
And the truth? The hardest part isn’t the workout… it’s walking through the door for the first time.
After that, you’ll wish you started sooner 💪
