ISO-Lateral Linear Leg Press.

Two sleds. No negotiation.

On an ordinary leg press you push the same plate with both legs, and the strong leg quietly takes over a little more every set. Here each leg has its own sled on linear rails, so you see exactly what each side can do, and can dose precisely when building back up after an injury. Friction is low, so the resistance feels the same all the way out and all the way in. The frame weighs 540 kg empty, so check both floor loading and that 2525 × 1420 mm actually fits before delivery. What you do not measure never gets even.
