Super easy to use and the resistance feels just right. The build is solid, nothing flimsy at all, and the movement is really smooth. I love how many different workouts I can do with it - worth every penny!

I get an amazing pump and sweat quickly with this. My wife also uses it by adjusting the resistance to her level, and she enjoys it as much as I do. Compact, easy to store, and a great investment for any home.

Exactly what I needed for home workouts.
I was tired of having multiple bulky pieces of equipment at home, but nothing really worked for my arms and chest the way I wanted. The CoreFlex Twister™ Pro is compact but insanely effective — within 3 weeks I noticed my arms looking more defined and my chest stronger. It’s easy to adjust resistance, so I can push harder every week. Definitely a game-changer for my fitness routine.
