Lift Intelligence
The FLEX device attaches to your barbell and measures the chosen exercise performance, velocity and power. The FLEX App intelligently receives and records movement metrics from the FLEX device, Workout details are securely synchronised with the backend Flex Server, allowing you, and your chosen friends to share and compare performance improvements over time.

Individual Athletes
FLEX is for those who are ready to take their training to the next level. FLEX allows individual athletes to train better, avoid injury and track their progress with accuracy. Using the same technologies and training methods as elite athletes, individuals are given real time metrics including Power, Velocity, Height and Dip on each and every lift.
With the rise in popularity of Velocity Based Training, individual athletes are able to take advantage of the FLEX as a way to pre-determine their training load. Velocity Based Training uses velocity as a biometric feedback tool to gauge weight training on a day to day basis. Basically, velocity output helps dictate how much load you should be adding or removing on a particular set, or if you should move on and try a new exercise altogether.
Take the guesswork out of your sessions and train with FLEX; with Lift Intelligence.

Remote Coaching
Keeping clients motivated and accurately tracking their progress are two common issues associated with online or remote training. FLEX removes the guesswork as a coach is able to track the progress of their client, regardless of how far apart they may be.
Utilising technology as part of a system is vital to the success of online coaching, and as FLEX is able to provide accurate data to individuals in the weight room, online coaches are now able to make decisions and provide informed programming.

Create Community
With the world demanding connectivity on every level, FLEX delivers community to its users. Create networks of likeminded individuals who will keep you accountable through your training.
For those Powerlifters and CrossFitters who are ready to step up their game, the best equipment is a necessity. With laser guided focus on barbell sessions, FLEX can be the tool which fills the hole in performance monitoring. Tracking progress in the weights room with accuracy is undoubtably beneficial to those in the community, especially those who are competing.

What’s New

Version 1.9.1


This release includes fixes we wanted to work on before the next feature update.

You won't see it, but anyone training offline gets a better saving process and we also made some fixes to the login process. For those that love the Workouts feature, we made some improvements to the saving process there too.

We've also gone ahead and tidied up a duplication issue in History that a few users might have been experiencing.

We are constantly searching for ways to improve performance, but we're also excited by new features and enhancements. Next release you can expect more of the latter!

Happy buyer

The unit shipped quick enough and after a bit of playing around I figured out how I like to use the app best. My workouts are far better compared to not having Flex. Can’t imagine going back to training without it.


Great app, great device

Great training feedback and helps get the most out of sessions. So easy to use. Even has a social function so I my friends can see my sessions and comment.
