ISO Arms

The lever-arm function completely changed how I do pressing and rows—being able to stop and start at any point in the rep is something I didn’t know I needed. Bolted right onto my series 5000 rack without any wobble, and now I’m hitting angles that dumbbells just can’t match.

I’ve been using this for a few weeks now, and the adjustable tension system is a game-changer for my setup. It fits perfectly into my existing rig and feels solid without any wobble. Definitely worth the upgrade over my old gear.

Mounting these was straightforward on my 4000 series rack, and the independent movement on each side finally lets me hit angles a barbell just can't reach. Only gripe is the pins feel a bit snug going in, but once they're seated, the whole thing is rock solid.
