About Via Fortis: Muscle Heat Map
Real strength is balanced. Via Fortis is a muscle balance tracker for lifters who train with intent. Built for those who train consistently and want to see what they’ve actually trained, not just what they lifted last session. Most apps log your sets. Via Fortis maps your training to your body week by week, so you can see where the work is landing, what’s falling behind, and whether your program is building balanced strength. Recommendations are built from your training, not a generic playbook. No social feed. No noise. Just your training, made visible. SEE WHAT YOU TRAINED Every workout is mapped to your body across 120+ exercises and three muscle tiers based on how directly each exercise works them. The Body Map shows which muscles you’ve covered across short and long term training windows. Spot gaps before they become weak points. WEEKLY BALANCE Weekly Balance shows how your training is distributed across Push, Pull, Squat, Hinge, and Core. A 12-month trend overlay shows whether your balance is actually shifting. One honest verdict tells you what’s falling behind. WATCH THE TRENDS Personal record detection runs automatically after every workout. Lift Progress charts show your estimated 1-rep max across one month, three months, or a full year. Strength Momentum compares your last four weeks to the four before, lift by lift, with concrete deltas. BUILT FOR BETWEEN SETS Fast set entry with smart defaults. A background-persistent rest timer with haptic alerts. Workout drafts that survive backgrounding the app or losing signal. Supersets in two taps. Cardio and conditioning logged in the same session as weights when you want them combined. YOUR GOALS. YOUR DATA Set strength goals against your own history. Track body weight over time. Log cardiovascular and recovery metrics. Progress is measured against you, not a population average.
