Koar - Strength Training

Choose your equipment. Full gym to only your bodyweight. Automatic logging and tracking. A progression engine that adapts to your body. HRV-aware rest, periodization.

KOAR adapts to your body and your equipment, not just your preferences.

Works on iPhone alone. Better with Apple Watch and AirPods. Full gym, dumbbells only, single barbell, elastic bands, or just bodyweight. KOAR builds around what you have.

Pick a science-backed program, or build one manually or with AI. Smart weight recommendations, heart-rate-based rest, per-rep tempo on your Watch.

This isn't a workout logger. It's a training system.

HANDS-FREE COACHING Put your AirPods in, put your phone down, lift. A warm studio-quality coach voice (Kira or Wes) narrates your session from first set to last. Exercise intros, rest countdowns, brace cues before heavy lifts, form reminders, halfway checkpoint. Works offline. No cloud, no setup.

INTELLIGENT PROGRESSION Every set feeds a progression engine built on exercise science. KOAR calculates your estimated 1RM using an Epley-Brzycki ensemble, detects stalls before you notice, and auto-adjusts volume and intensity. When you're ready to progress it adds weight; when you need a deload it catches that too, using severity-weighted analysis across your last 4 sessions instead of waiting for you to fail twice.

ADAPTS TO YOUR BODY A 5-second wellness check-in (energy, sleep, mood) calibrates every workout. KOAR reads HRV and nutrition from Apple Health to adjust volume and fuel recovery, and integrates menstrual cycle data to adjust intensity by cycle phase.

APPLE WATCH COMPANION Live heart rate with zone coloring, rest timers based on heart rate recovery (not just clock time), and rep detection tuned per exercise. If your Watch disconnects mid-workout, your iPhone is the source of truth — no data lost.

TEMPO COACHING KOAR prescribes lifting tempo (eccentric, pause, concentric, pause) and guides you through each phase with haptic pulses on your wrist.

COACHING INSIGHTS A Coach tab surfaces patterns you'd miss on your own: masked fatigue, volume response profiles, and wellness-performance correlations unique to you.

PERIODIZATION THAT RUNS ITSELF Mesocycles with automatic phase progression, volume landmark tracking per muscle group (MEV/MAV/MRV), and goal-aware deload management. Hypertrophy deloads cut volume with lighter weights. Strength deloads slash volume but keep full working weight to maintain CNS readiness.

BUILT FOR EVERY LEVEL Beginners get guided weight discovery with live coaching cues. Intermediate lifters get periodized mesocycles with automatic deloads. Advanced lifters get RPE/RIR autoregulation and sex-based programming.

EARN YOUR PROGRESS XP tied to training quality, not just showing up. 20 rank tiers, 17 badges for real milestones like 12-week streaks and pressing your body weight, and streak flames that evolve from Bronze to Obsidian over a full year.

AI PROGRAM BUILDER Describe your ideal training in plain English and KOAR generates a complete periodized weekly plan that respects evidence-based volume landmarks.

STRAVA SYNC Completed workouts post automatically to your Strava feed as Weight Training activities.
