Selectorised machines are the backbone of most commercial strength floors. This guide covers cams, weight stacks, biomechanics and durability when specifying pin-loaded kit.
A good cam matches resistance to the muscle's strength curve — the difference between a smooth machine and a janky one.
A well-designed cam varies resistance through the range to match the muscle's natural strength curve.
Correct pivot points align the resistance with the joint axis for safe, effective loading.
Multiple starting-position adjustments suit different limb lengths.
The weight stack and cable routing decide feel, safety and maintenance.
Match the stack to your members — too light limits advanced users, too heavy wastes budget.
Smooth, low-friction cable routing gives a consistent feel and lasts longer.
A secure, magnetic selector pin prevents accidental disengement under load.
In a commercial gym, upholstery and cables take the most abuse — specify for the long term.
High-density foam and double-stitched vinyl survive daily commercial use.
Powder-coated frames resist chips and corrosion in a sweaty environment.
Confirm UK parts availability for upholstery, cables and pins.
