Caring for your Primal Strength product

Cleaning or disinfectant/sanitising spray should not be sprayed directly onto this product, it can remove the paint/ceramic coating/ionised/chromed finish and can cause rust. This product must only be used indoors in a temperature controlled environment and be left dry. Any damage to products from chemical cleaning products voids the product warranty.


The Primal Strength Plate-Loading ISO Lever Machines have been engineered to work in the natural motion of the body in order to optimise the isolation of the intended muscle groups. The Machines converge and diverge in a natural, arcing motion, guaranteeing users the maximum muscle contraction whilst providing the optimum safety when training.

ISO Lever Plate-Loaded Machines have many benefits, including:

  • Maximum muscle-extension in a supported position
  • Converging and diverging range of motion
  • Safely isolates muscle groups whilst allowing maximum weights to be lifted
  • Ensures a natural lifting motion

The Commercial ISO Seated Calf Machine provides users with a full range of motion to stretch and press their calf muscles. Calf muscles can be difficult to activate through a full range of motion. The Primal Strength Calf Machine provides a solution to this by allowing users to adjust the knee-pad height to ensure they get a maximum range of motion. The sealed bearings allow for a smooth, calf-pressing action.

Simply add the weights required, adjust the seat’s knee-pad height using the metal pop pin, release the support arm and you can utilise the machine for heavy duty calf raises. The design allows users to comfortably use the machine as a single-leg or dual-leg calf press. The extended weight-pin holder provides a high maximum weight capacity and the non-slip, diamond-cut foot plates ensure user safety even when pressing a heavy load.

The Commercial ISO Calf Machine is extremely heavy duty and is backed by a lifetime frame warranty. The ISO Calf Press is one of 8 Core Primal Strength ISO Machines and the range is perfect for any sports facility or commercial gym. It comes in Matte Nero with premium rip-resistant pads. The quick release knee-pads allow users to set the machine up quickly to the desired height.
