Add more exercise options to your power rack without taking up more floor space with the ISO Arms attachment. These plate-loaded arms replicate the moveable handle found on other gym machines. Simply attach the arms to the outside of a compatible REP rack, and adjust the handle up, down, or in another orientation for a wide range of dynamic exercises. The bearing design allows the arms to travel through a full 180-degree arc. Or lock the arms in place for static moves, like dips and pull-ups.
The ISO Arms can be used independently for unilateral movements or together. The arms are heavy-duty, made with a four-way hole pattern so you have a completely modular arm that’s easy to slide up, down, and in different directions, or add J-cups for more versatility. The eyebolt allows lifters to easily connect a belt squat attachment. The knurled handles are adjustable, or you can take them off entirely. When you’re done using the ISO Arms, lock them upright and out of the way to save space.

Can ISO Arms be used on the inside of your rack?
No. They are only for use on the outside of the rack.
What is the easiest way to adjust the ISO Arms?
Start by installing them as far down as possible. Starting at the bottom allows the weight of the arms to be supported by the ground. During use, we suggest using additional pins to lock them in place. This allows you to use the second weight horn as a second handle for ease of adjusting.
Are the ISO Arms compatible with the SR-4000 and PR-4100?
Do the ISO Arms work with the PR-4000 Power Rack?
Yes (4000 Series option). Make sure you choose the right series for your rack. Note: If you have the PR-4000 Power Rack, you will only be able to use one pin to secure each ISO Arm to the upright due to the hole spacing on the brackets. The arms are still safe and useful.
Will the ISO Arms work with 80” uprights?
Yes, but you can max out on the height of the upright. The 80” uprights provide a limited range, because the shorter rack has fewer holes and less space.
Do I need to bolt my rack to the floor to safely use the ISO Arms?
Yes, if used on a PR-5000 or PR-4000 power rack. The Apollo Half Rack and Omni Rack do not need to be bolted down to use the ISO Arms.
Will the ISO Arms fit on all 3x3” power racks?
We cannot guarantee compatibility between REP items and non-REP items due to manufacturing and machining differences.
Are the ISO Arms bad for my rack?
No, they even have a plastic lining that protects the powder coating on your uprights. Moving this product up and down may leave behind some temporary residue from the protective lining.
What exercises can you do on the ISO Arms?
You can do all kinds of exercises: rows, deadlifts, squats, a variety of presses, belt squats, hip/glute thrusts (with leg roller attachment), monolift bench presses, banded jumps, and more. Or lock them securely in place for exercises like dips, L-sits, and pull-up variations.
How much weight can the ISO Arms handle?
The arms are heavy duty, made from 3x3” 11-gauge steel. You can fit up to seven 45lb iron plates on each arm.
What spring clips are compatible with the ISO Arms?
The springs clips included. REP's standard spring clips are too big.
