Exercise technique

Check the rails

Safety stops
Set the safety limit just below your squat depth.
Position
Place the bar on your upper back and position your feet to suit the rail path.
Unlock
Rotate the hooks after firmly planting your feet.
Squat
Bend your knees with your feet positioned so the rails do not force your back out of position.
Rise
Keep your knees pointing with your feet as you raise the bar along the rails.
Rack
Check that both hooks are seated in their supports.

Key technique points

Account for the angle of the rails.
Do not position your neck beneath the bar.
Test your foot placement with the empty bar.
Avoid rotating the hooks during a repetition.
Use the lower safety stops.
Do not step out from under the bar before locking it.

Common mistakes

Incorrect foot placement

A stance that does not suit the fixed rails restricts the hip and knee paths.

Engaging only one hook

Uneven racking makes it uncertain whether the load is secured.

Skipping the safeties

Without a lower stop, there is less margin if a repetition fails.

Loading the neck

Placing the bar on your neck instead of the muscular shelf increases pressure.

Fighting the rails

Forcing your torso along another path disrupts a controlled squat.

Snapping the knees straight

Slamming into the top position reduces load control.
