Out with the Old, In with the Evolution: How the 1, 3, 5 Series Builds on Goliath and Samson

TRAIN YARD x BLK BOX-099 Large.jpegAt BLK BOX, we’ve never been content to stand still. Innovation is part of our DNA. That’s why the launch of the 1, 3, 5 Series marks more than just a product update — it’s the evolution of strength training systems that began with the now-iconic Goliath and Samson ranges.

Why Retire Goliath and Samson?

Goliath and Samson were born from the need to offer durable, high-spec rigs and racks tailored to the demands of serious training environments. Goliath was designed around 60x60mm uprights — dependable and cost-effective. Samson levelled up with 80x80mm uprights, greater customisation, and strength to support elite performance.

These ranges paved the way for BLK BOX’s rise as the UK’s leading manufacturer of strength equipment. But the landscape has changed — and our clients’ needs have too.

Facilities now want smarter modularity, faster lead times, aesthetic cohesion, and training systems that can adapt and evolve.

Enter: The 1, 3, 5 Series

Inspired by everything we learned from Goliath and Samson, the 1, 3, 5 Series was created to provide clearer choices, smarter design, and greater performance at every tier.

1 Series – Speed Meets Simplicity

  • Successor to Goliath in smaller personal training studios and home gyms

  • Built from 60x60x3mm steel, like Goliath — but redesigned for easier assembly and faster shipping

  • Features 75mm hole spacing and sandwich J-Hooks as standard

  • Sleek black-only aesthetic, kept in stock for rapid delivery

This range removes complexity without compromising performance — perfect for those who want professional-grade kit, fast.

3 Series – Modular, Scalable, Custom

  • A brand new range with 70x70x3mm uprights for increased durability

  • Fully modular, expandable, and attachment-ready

  • 4-way numbered hole spacing ensures consistent setups

  • Available in 14 colours with custom branding options

3 Series is designed to grow with your gym, offering independent operators a future-proof solution that adapts to changing needs.

5 Series – Elite Without Exception

  • Direct successor to Samson, taking every strength and refining it

  • Constructed from 80x80x3mm steel — ultra-durable and backed by a lifetime guarantee

  • Includes Westside, numbered, hole spacing, advanced testing attachments, and full customisation across branding and colour

  • Stainless steel upgrade available for the highest-performance demands

Used by Premier League clubs and world-class performance centres, the 5 Series is for those who demand no compromise.

More Than an Upgrade — It’s a System

Unlike Goliath and Samson, which existed as two broad product families, the 1, 3, 5 Series brings clarity and progression. Each tier caters to a specific audience:

  • 1 Series: Simple, fast, ready-to-go

  • 3 Series: Adaptable, custom, scalable

  • 5 Series: Elite, high-spec, engineered for peak performance

Each series shares attachment compatibility and design language — allowing facilities to mix and match or grow from one tier to the next without starting over.

Built on Legacy. Designed for the Future.

Goliath and Samson laid the foundations. The 1, 3, 5 Series builds the next chapter — smarter, sharper, and stronger than ever.
