Calibrex 3 User Testimonials

Early Adopters Love Calibrex 3

I didn't think you can do a guided workout class without a trainer. I started laughing the first time I heard it speak out loud but a few reps in I felt like I was in a private workout class.

It felt so strange at first that I didn't need to use my phone at between sets. It tracks all my reps, tells me what to do next and counts me down!
β€” Helen PCalibrex 3 Beta Member
Hardware shipped quickly and set up was easy, don't need anything beyond whats in the box. Gives me great insights into where I'm at and when it's time to lift heavier. I finally put these dusty dumbbells to use lol

I went from being shy to doing full blown strength workouts all by myself within 2 weeks!

Glad to see something for weights in the fitness tracker space this has given me all the data I could reasonably ask for, new features roll out continually, etc. Name another wearable option for lifting at this price point?

Planning workouts in my biggest nightmare when it comes to going to the gym. This gives me a new workout, all I have to do is show up.
β€” Georgia TCalibrex 3 Beta Member
I've been going to the gym for 3 years and for the first time in a while I got stuck in a plateau. Can't rely on the same ol' split every time. Lifting has become more fun now that I have numbers to compare from each session.

I'm a calisthenics guy so I mainly use the body clip to track my workouts. Honestly the automatic rep tracking and set countdown are godsent. Exactly what I needed for progressive overload.
