Guys… it’s warm.
We know it’s warm.
The gym unit is essentially a large metal air fryer.

We’ve put the big fans out for your convenience…
although they’re mainly just blowing hot air into your eye balls.

So before you overheat and end up starfished on the floor halfway through lunges, here’s a few tips:

💧 Drink water before training.
A White Monster and enthusiasm isn’t good enough.

🧂 Get some electrolytes in.
If your sweat tastes like the ocean, it’s probably time.

👕 Wear sensible kit.
This isn’t the day for an all-black hoodie and joggers combo.

🏃 Don’t be a hero.
It’s 30 degrees. Nobody cares if you shave 4 seconds off your SkiErg split.

🥵 Feeling dizzy? Sit down.
No shame in a tactical floor lie-down.

💨 And yes, you’re allowed to stand directly in front of the fan between sets.
That’s basically become its full-time job.

See you in the sauna 👍
