Rack Pull with Bands

Trains the Spinal Erectors.

How to do it

Set the safety pins in a rack at the height you want to pull from, usually knee level or just below.
Loop a band over each end of the barbell and anchor both to the rack base.
Stand with the bar over the middle of your feet and take an overhand or mixed grip.
Set your back flat and your chest up, then take the weight without the bar moving.
Stand up against the bands, taking on more tension with every inch.
Lower under control back onto the pins and let it settle before the next repetition.

Bouncing off the pins. The dead stop is the point of a rack pull; a rebound reintroduces exactly what the pins removed.
Setting the pins by what is convenient. The height decides which part of the pull is trained, and above-knee and below-knee are different exercises.
Loading it against a full deadlift. A shortened range plus band tension at the top is a combination with no equivalent number.
Letting the bands pull the bar down onto the pins. The descent is controlled; a band-driven drop onto steel pins is loud and hard on the bar.
