Exponent Edge Infinity Arm 2.0 Review

The Exponent Edge Infinity Arm 2.0 is a rack-mounted support attachment that adds adjustable positions for presses, rows, and accessory work. We recommend it for home-gym owners who already have a compatible squat rack and want to add exercise options without placing another full station on the floor; use code SEBASTIANBASSOL through our Exponent Edge promo code page.

Why we recommend it

The core strength is adjustability. The Infinity Arm has several pivot and support-pad positions, so you can set the pad where a movement needs support instead of adapting every exercise to one fixed bench height. That makes it useful for chest-supported rows, dumbbell presses, flyes, curls, and other accessory work where a stable torso or arm position helps you focus on the lift.

It also folds up or down and can be removed from the rack. For a garage gym or basement where floor space matters, being able to move the attachment out of the way is a meaningful advantage over another freestanding station. The unit is substantial, but its footprint stays tied to the rack rather than expanding across the room.

Owner feedback reinforces the same appeal: people value the range of positions and the number of movements it opens up. We also see a real comparison point in the REP Pegasus. Some lifters prefer its seat-and-leg-roller format, while the Infinity Arm is the more direct choice when the priority is a flexible support arm that mounts to a compatible rack.

What buyers love

The versatility is the consistent draw. Owners describe using the arm for chest-supported rows and other supported movements, and they like that changing the setup does not require a separate bench or dedicated machine for every exercise. The product can also work with dumbbells, barbells, and kettlebells; cable exercises depend on the rest of your rack’s cable system.

The storage story matters just as much. When the arm is not in use, it folds against the rack or comes off entirely. That makes it easier to keep a compact training area usable between workouts instead of leaving one attachment permanently in the way.

Who it’s for (and who should skip it)

This is a strong fit for a home lifter who owns a compatible rack and wants more supported positions for upper-body work. It is especially appealing if you already have dumbbells or a cable setup and want to get more movement options from the same space.

Check your rack before you buy. Exponent lists standard compatibility with three-by-three-inch and two-by-three-inch uprights, with either one-inch or five-eighths-inch holes. A two-by-two rack requires a separate UHMW adapter. The attachment’s listed six-hundred-pound capacity is a manufacturer specification; use it only when the arm is installed on a compatible, properly secured rack and follow the product and rack instructions.

Skip it if you do not own a rack, need a cable station of its own, or mostly want a fixed seat with leg rollers. It is a specialized rack attachment, not a substitute for a complete cable machine or a full adjustable bench.

How it compares

REP’s Pegasus is the alternative to consider if you own a REP four-thousand or five-thousand rack or cable system and want a seat plus removable leg rollers for cable and supported work. The Infinity Arm is more compelling when you want to adjust a support pad around a wider range of rack-based movements and keep the setup compact.

Our verdict

The Infinity Arm 2.0 is a smart upgrade for a compatible rack when you want more supported angles and less equipment taking up floor space.
