What is your maximal strength? Which weight should you use in your next training session to optimize results? PowerLift is the first scientifically designed app to measure your 1-Repetition Maximum (1-RM) in the most accurate way possible.

Knowing your 1-RM in every single training session is essential to adjust your training intensity and get the best adaptations. However, performing an actual 1-RM test could be dangerous and fatiguing and, if performed every day, it will most likely lead to overtraining or injuries.

To solve this problem, PowerLift uses scientifically validated algorithms that can estimate your 1-RM with high precision by simply recording your exercise. To do this, PowerLift uses the high-speed video recording available on most iPhone and iPad devices to measure the velocity at which you are performing the exercise, which is highly correlated with your maximal strength capabilities. This novel approach is used by sport scientists and top-level coaches thanks to advanced instrumental like linear transducers or force platforms, but now you can measure your 1-RM like a pro just with your iPhone or iPad!

PowerLift is very intuitive and easy to use: you just need to record one repetition of the desired exercise with 1 to 4 different submaximal loads and select its start and beginning in the app with its accurate frame-by-frame navigation. After that, PowerLift will show you your 1-RM!

Let's say you got a workout which includes 4x5 repetitions at your 80%1-RM. Well, you just need to pick a load and record one repetition with PowerLift. It will tell if that load really corresponds to your 80% or not, so you can increase or decrease the weight to train in the right zone!

PowerLift has a lot of great features that will help you measure your 1-RM in a very simple, yet powerful way:

-Estimates your 1-Repetition Maximum (1-RM) in a very simple way by measuring your movement velocity, a novel approach used by top sport scientists and elite coaches
-Measures what %1-RM corresponds to a specific load so you can adjust your training and get the best results
-Calculate your movement velocity to monitor your performance!
-Analysis of velocity loss to monitor fatigue.
-Works with some of the most widely-used upper and lower body exercises: bench-press, deadlift, pull-up, back squat & hip thrust. More exercises coming soon!
-Multi-team and multi-user: create as many teams and users as you want
-Progress analysis: save as many tests as you want and see your progress through time to check if you have improved or worsened your performance. You can even see the percent of change from one test to another!
-Data export: export your whole database to a csv file and play with your data in Excel!
-Universal app: install PowerLift in your iPhone and use it in your iPad or viceversa!

Also, PowerLift includes a lot of great new features for iOS devices, such as:

-3D touch quick actions: import a video or go to your users list right from your home screen!
-App thinning: the size of the app is significantly reduced

PowerLift, train smarter and get the best results!

Note: PowerLift is optimized for devices with slowmotion cameras. In other devices, the accuracy of the calculations might be lower

Amazing app! As all Balsalobre's create! Good feed back when you understand how to work with tha app!


Not living up to expectations

So far this app has been a disaster for me. I have wasted a lot of time trying to get it to work and have never succeeded. If you screw up using the UI in any way while trying to do your initial test, you've wasted your time and have to start all over. The one time I was able to complete it, it wasn't able to give a meaningful 1RM. So far, it's just been a waste of $10 and I regret purchasing it.
