OVERVIEW

Reviews Summary
Customers say this cable system transforms their rack into a versatile functional trainer that saves significant space. The pulleys operate smoothly and feel like commercial gym quality, with easy height adjustments and excellent build quality. Many appreciate how it adds numerous exercise options while maintaining a compact footprint. Users consistently praise the smooth cable movement and professional-grade feel. Common feedback includes recommendations for the weight stack upgrade, especially for heavier exercises like lat pulldowns and rows. Some mention installation takes several hours but is straightforward with proper instructions. A few note the lowest pulley setting could be lower for certain exercises, and occasional minor issues with pulley stiffness initially that resolve with use.

    Perfect addition!

    I debated for a while between buying a standalone functional cable machine or adding one to my rack, and I’m really glad I went with this option. Installation wasn’t too difficult, but plan on setting aside a full day and bringing some patience. Once everything was dialed in, the cables moved smoothly and the adjustability is great. Biggest bonus: it saves a ton of space since I didn’t have to squeeze another machine into the gym. Only regret is that I didn’t opt for the stack upgrade.

    Absolute incredible machine and high quality! The one thing I don’t have buyers remorse about.

    Great system with a single pain point

    System is fantastic with one small caveat - the lowest setting is still pretty tall for ankle level exercises, benched preacher curls etc. Easy to install and very smooth once I siliconed the plate uprights.

    Amazing versatility

    I think this is the most overlooked REP product for any rack… the Athena allows you to build out a 4 or 6 post the way you want without being beholden to a bunch of extra pulleys or weight stacks blocking valuable real estate. The 6 post is great if you want to leave a dedicated j cup spot for bench or standing barbell movements without interfering with your trolleys on the front
