🚨 GYMLECO SEATED CHEST PRESS 021 🇸🇪

I’ve used a LOT of chest machines over the years… and I’ll say it:

This is the best chest machine I’ve ever used. 🤯

The movement. The stretch. The contraction. The loading profile. Everything about it just feels right.

We’re constantly looking for ways to improve the Mayhem floor — not just adding more equipment for the sake of it, but bringing in machines that genuinely deserve a place here.

And this one absolutely does. 🔥

Come and try it for yourself.

🚨 NEW MACHINE DAY 🇸🇪

Introducing our brand-new Gymleco Hack Squat. Big deal this one 🥰 at the Mecca of Boston 🔥

This isn’t just another machine added to the floor. Gymleco equipment is built in Sweden, has an incredible reputation worldwide, and represents exactly the standard we want Mayhem to keep moving towards.

Every penny we can, we continue to reinvest back into the gym.

Better equipment.
Better facilities.
A better gym for our members.

And we’re nowhere near finished.

🔥 TWO more brand-new machines of this standard are already ordered and landing in October.

👀 Plus, we’ve got a couple of completely different surprises arriving within the next month that are going to add another level to what Mayhem offers…

We’re constantly looking at what we can improve, what we can add and where we can take the gym next.

No standing still. No taking the members for granted.

You support Mayhem. We support you. 🖤🧡

Now… who’s christening the new hack squat? 😈🦵
