81%The Strong Score
Formula v4.0.0
PUBLISHED.
BOUNDED.
Your chosen result for The Strong Score is the one you rank with. Focus, exact weights, evidence coverage, freshness, and verification stay visible so powerlifters, endurance athletes, and hybrid competitors can make an honest comparison.
What changes when you train
THE NUMBER IS THE START.
Know what comes next
Get rep and weight suggestions based on your goal, how recent sets felt, today's readiness, and the equipment you actually have.
Classes worth claiming
Opt-in rankings by age, bodyweight, physiological division, source verification, and formula version.
Use the data you have
Connect Apple Health or Health Connect for optional sleep, pulse, aerobic fitness, and body data. Missing information stays missing, never zero.
Free means useful
TRAINING STAYS OPEN. AI COACHING IS OPTIONAL.
Workout logging, planning, The Strong Score, lift models, progress, health connections, profiles, and community remain accessible. Strong Coach Pro funds optional AI workout generation, revision, adaptation, and weekly summaries. It never buys a higher score or ranking.
Train with judgment
ESTIMATES ARE NOT COMMANDS.
TheStrongApp is a fitness and training tool, not a medical device. It does not diagnose, treat, cure, or prevent any medical condition. Suggested loads, estimated maximums, scores, readiness signals, and AI plans may be incomplete or wrong. Choose only activity you can perform safely, stop for concerning symptoms, and consult a qualified healthcare professional before beginning or materially changing an exercise program.
