How Iridium Programs This

Rack Pulls generate high systemic fatigue due to heavy loading, so Iridium validates your recovery score using sleep data and recent metabolic estimates before scheduling them. The algorithm also scans your 7-day training history to strictly manage erector spinae volume, ensuring you don't exceed your Maximum Recoverable Volume following other heavy hinge exercises.

Form Cues

Position the bar against your shins at the start
Pull the 'slack' out of the bar before lifting
Drive your hips forcibly forward to lock out
Keep your chest tall and shoulders retracted
Brace your core tightly like you're about to be punched

Don't

Don't let your lower back round at any point
Don't hyperextend or lean back excessively at the top
Don't jerk the bar off the rack
Don't let the bar drift away from your thighs
Don't shrug your shoulders up to your ears

Common Mistakes

Bouncing the weight off the rack between reps
Starting with hips too high (stiff-legged)
Bending the arms or using biceps to pull
Soft knees at lockout
Looking up at the ceiling and craning the neck

Muscles Worked

This exercise is a powerhouse for the entire posterior chain, placing primary stress on the erector spinae to maintain spinal rigidity. It provides intense stimulation for the upper and middle trapezius, rhomboids, and lats due to the heavy static hold, while the glutes and hamstrings work hard to extend the hips.
