STOP GUESSING. TRAIN WITH CONFIDENCE. Cornerstone Strength helps you know what to do next, and understand why. Every set you log becomes useful context: what the plan called for, how you performed, how hard it felt, and how your training is trending. Cornerstone turns that context into clear guidance while keeping you in control. KNOW WHAT TO DO NEXT Get your next weight, sets, and reps suggested right on the workout screen. Smart Suggestions use your recent performance, logged effort (RPE/RIR), time between sessions, and program targets. Every suggestion includes a plain-language reason. Apply it with one tap, adjust it, or keep your plan. It is a starting point, not a rule. EVERY WORKOUT HAS A PURPOSE Choose from programs written by real strength coaches using proven periodization for strength, hypertrophy, athleticism, or a mix. Enter your numbers and train, customize a program, or build your own from scratch. Percentage-based programs calculate working weights from your training maxes automatically, so the plan is ready when you are. SEE THE TREND BEFORE THE NEXT PR Understand whether the work is working: - Estimated 1RM (e1RM) trends - Training volume by muscle group - Weekly volume and muscle-balance insights - Personal-record history and automatic PR detection - Workout consistency and streaks - Month, 3-month, year, and all-time views LOG WITHOUT LOSING YOUR FLOW - Weight, reps, RPE, RIR, and AMRAP support - Previous performance beside today’s set - Structured program sessions or quick workouts - Background rest timer with audio and vibration alerts - Exercise swaps, notes, and duration tracking - Band tracking for accommodating resistance - Apple Health workout sync 500+ EXERCISES Find movements for a commercial gym, garage gym, or anywhere in between. Browse by muscle group or equipment, including barbells, dumbbells, kettlebells, machines, cables, bodyweight, trap bars, specialty bars, and more. SHARE THE WORK Turn a completed workout into a clean card with PRs, top lifts, and muscle-group balance. Share it to Instagram Stories, save it to Photos, or send it to a training partner. START WITH 30 DAYS OF PRO- FREE Every new account gets 30 days of Cornerstone Pro with every program, Smart Suggestions, and full analytics unlocked. No credit card required.
