About KeyLifts - 531 Workout Log
KeyLifts takes the math out of the 5/3/1 program so you can focus on getting stronger. Everything is planned out for you. Know exactly what you need to do as soon as you step into the gym. KeyLifts automatically calculates all your sets so you can focus on hitting new Personal Records. Planning and tracking a 5/3/1 program is time-consuming and hard. You have to calculate your training max and then calculate every single set based on your training max. It doesn't have to be like that. You could just walk into the gym every day knowing exactly what you need to lift. KeyLifts takes the math out of the 5/3/1 program so you can focus on getting stronger and hitting new PRs. Every cycle you have to redo the entire planning process, but not anymore! With one button press, you can create a new cycle with all the weights automatically calculated for you. If you haven't hit your ultimate strength goals yet then maybe it's because you have to spend so much time at the gym calculating weights for each set. Stop wasting your precious energy. Just plug in your numbers to KeyLifts and go. The 5/3/1 program is amazing for strength gains but your energy and time are wasted trying to figure out what plates you need for each set. In the upgraded Pro version you get a Plate Calculator so you focus on the things that matter. Getting stronger is about putting in the work every week but it's hard to see the progress you are making. The Pro version includes graphs of your one-rep maxes over time. Feel confident knowing you are doing the right things and making progress. If you are the type of person that likes to track everything the Pro version also includes the ability to add and track Joker sets and assistance exercises. Free Features: - Plan an entire 5/3/1 cycle with one button press - Alerts when you hit a new Personal Record (PR) - Warm-up sets - Rest Timer - 150+ templates from the 5/3/1 Books - Build your own custom templates - Track assistance exercises - Track Joker sets - Delete or swap exercises during a workout You can subscribe to the Pro version on either a monthly or yearly basis. Pro Features include: - Automatic Training Max progressions - Cloud backup and sync between devices - Plate Calculator - Graphs Terms of use: https://www.keylifts.com/terms Privacy Policy: https://www.keylifts.com/privacy This app integrates with Apple Health to sync your weight and workout data.
