CONCEPT — a conversion redesign by Slice of the Pie Marketing for Westside Barbell. Back to overview

The Original Conjugate Bands

Pioneered by Louie.
Still made the same way.

Dick Hartzell invented the resistance band. Louie Simmons put it on the barbell. Every band on this page traces back to the dynamic-effort work that built world records in the original gym — layered latex, matched in pairs, rated by real resistance.

Why it matters

Accommodating resistance, done right

Bands load the top of the lift where you're strongest and teach the bar to accelerate through the whole range. That's the dynamic-effort method — the same approach behind 140+ world records at Westside. Cheap bands snap and pull uneven. These don't.
