Calibrex 2 is the first exercise tracker designed for physical exercise.

We've found that most fitness trackers focus mainly on cardiovascular metrics and steps but nothing that can really help us understand our progress in the gym. Calibrex brings technology that currently only pro athletes in pro sports facilities have, it a portable and affordable form factor.

Calibrex 2 uses magnets to attach onto many types of equipment including: any metal, good quality barbell, any gym machine with a weight stack, free weights when using the Calibrex Wristband and bodyweight when using the Calibrex Body Clip.

The Calibrex 2 was designed after collecting 1M reps with Calibrex 1, and working with over 1,620 users, collecting vigorous feedback, to create the most seamless, frictionless experience during exercise.

The battery is designed to last about one week or 5 one hour sessions.

Now that users finally have objective numbers for each performed rep and set in the past, you can know at exactly what speed you usually move certain weight (i.e. you know that you can bench 135lbs at 0.75m/s. If today you're feeling strong, you should try to set a target speed a bit higher than that, or increase your weight by 5-10lbs, and try to maintain that speed.)

The live trainer will show a blue color if you pass the speed target, or orange if you don't. You'll know in real-time.

By experimenting with your own load/speed relationship, you can uncover tons of lifting habits you otherwise wouldn't be able to pay attention to.
