BREAKING NEWS: the stigma against Smith machines is over! This Smith Machine Rack Attachment will supercharge your size & strength in an ultra-compact footprint. Now, if only mullets would come back in style…

This widely compatible unit upgrades your 3” x 3” power rack into a beloved bodybuilding beast without the hefty price tag or space requirements.

Bring your own 25-30mm diameter barbell (BYOB) for a higher starting weight and to optimize the attachment for your next training cycle. Or, snag the hollow 36lb Smith bar for an easier assembly & one-and-done solution for all exercises. With a 600-pound total weight capacity, it’s ready for your heaviest ambitions.

Mount this rack attachment on the inside of your rack without taking up any additional footprint in your gym, or attach it to the outside — sitting just 10" off your uprights! Change between a straight or angled bar path with a few simple adjustments to the mounting brackets, making its fixed path feel as natural as possible for your body.

Hit all the staple lifts: squats, presses, rows, and Bulgarian split squats (why are they ALWAYS here?!). But that’s just the start. Incorporate heavy negatives on compounds. Isolate individual muscles with JM presses. You can even rehab stubborn aches in your posterior chain with single-leg Romanian deadlifts.

Recommended Set-Up: Mount the upper brackets to the top of your uprights & the lower brackets to your crossmembers (inside rack) or front foot stabilizers (outside rack). Brackets can be mounted to your uprights only, but a dropped bar could permanently damage the unit.
