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.

Free to start. Works on iPhone alone, better with Apple Watch and AirPods. Full gym, dumbbells, a single barbell, bands, or just bodyweight, KOAR builds around what you have.

Pick a science-backed program, or build one yourself 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 (Kira or Wes) narrates every set: exercise intros, rest countdowns, brace cues before heavy lifts, form reminders, a halfway checkpoint. Works offline, no setup.

INTELLIGENT PROGRESSION Every set feeds a progression engine built on exercise science. KOAR estimates your 1RM with an Epley-Brzycki ensemble, detects stalls before you notice, and auto-adjusts volume and intensity. It adds weight when you're ready and calls a deload when you need one, using severity-weighted analysis of 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 recovery, and uses menstrual cycle data to tune intensity by phase.

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

TEMPO COACHING KOAR prescribes lifting tempo (eccentric, pause, concentric, pause) and guides 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 deloads. Hypertrophy deloads cut volume with lighter weights; strength deloads cut volume but keep full working weight for CNS readiness.

BUILT FOR EVERY LEVEL Beginners get guided weight discovery with live 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 year.

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

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