ISO Arms Review – In Summary

That’s our review of the ISO Arms from Rep Fitness.

If you’ve invested in a power rack, why not give yourself even more workout options?

ISO arms can certainly assist you in doing various exercises, particularly if you are looking for new ways to train within a limited space.

This is a good investment any strength trainee can make, especially if you don’t want to go through the hassle of driving to the gym, waiting for equipment, not having enough time, etc.

Looking for more isolateral training options? You might want a functional trainer or cable machine.

They are assembled with pin and sliding capabilities, which makes them convenient and advantageous to use. The handle improves the arms’ performance when removed, allowing you to perform belt squats, bench press off, or a mixture of other workout moves.
