A training tracker that tells you what to fix,
not just what you did.
Most apps log your sets and call it a day. Atlas logs strength and endurance in one place — then maps it onto your body and shows what's neglected, what's drifting, and what to train next.
Strength · Endurance
Heat-mapped onto a body diagram
Consistency, balance, neglected, PPL, scores
One app for the whole athlete.
Not just sets and reps. Atlas tracks strength and endurance side by side — plus the insights to spot when one is starving the other.
Strength logging that respects equipment
Per-set weight × reps, with 1RM estimated using the right multiplier — barbell, dumbbell, or bodyweight. Pull-Up isn't lying to you about 1RM anymore.
Endurance + VDOT, not just distance
Log a run with distance and time; pace and Daniels' VDOT compute live. Compare yourself to yourself across the year.
A calendar of your whole life
Weight, illness, vitamins, notes — quick-logged in two taps onto the same timeline as your training, so you can see why a week went missing.
Body-map heat chart
Front and back anatomical figures, painted by training volume across a window. See at a glance which muscles you've actually been training — and which you've been skipping.
Insights that argue with you
Push/Pull/Legs balance, neglected muscle groups, consistency streaks, score-vs-target — five reports that turn your log into a coaching brief.
Programs with deload weeks
Per-set percentages of your 1RM, weekly patterns, deloads. Schedule a program and the Log tab pre-fills your next session.
Three taps to a session. Zero spreadsheets.
Pick or repeat
Tap a "Continue" chip for last session's exercises, or search. Sets and weights pre-fill from your last log — fast iteration on whatever you were already doing.
Log the sets
Type weight × reps, hit Log. Saved on every change — no submit button, no losing a workout to a flaky tab.
Read the map
Open Insights or the body map. See where you've been training, what's drifting, what to target next session.
Most apps log. Atlas analyzes.
Strong logs strength. Strava logs cardio. A spreadsheet logs whatever you remember. None of them tell you that you haven't trained your hamstrings in 17 days. Atlas does.
