COACH-DESIGNED TRAINING PROGRAMS
Programs are written by real strength coaches using proven periodization methods. Whether your focus is strength, hypertrophy, athleticism, or a combination, Cornerstone Programs has you covered. Just select a program, plug in your numbers, and start training. Or, use one as a starting point, and make adjustments to fit your needs.
WORKOUT LOGGING THAT UNDERSTANDS LIFTING
Stop doing the math in your head. Log sets with weight, reps, RPE, RIR, and AMRAP support. The app knows the difference between a heavy compound set and an accessory movement and adjusts intensity tracking accordingly.
Pick a percentage-based program, enter your training maxes, and Cornerstone Strength automatically calculates your working weights for every set.
Features include:
- Intensity tracking with RPE and RIR
- Advanced progress charts and analytics for training volume
- Structured program sessions or quick freestyle workouts
- Customizable rest timer that keeps running in the background
- Audio and vibration alerts when rest is over
- Automatic PR detection when you hit new records
- Band tracking for accommodating resistance
- Workout notes and duration tracking
