Base Layer Coaching

Your AI coach reads your Apple Health data and builds a real training program. Set your goals, connect your watch, and train smarter.

Base Layer is a fitness coaching app that builds your training program from real health data — heart rate, HRV, sleep, workout history — and adapts every week.

Tell your coach what you're training for. A ski trip, a marathon, keeping up with your kids, or just getting stronger. Connect Apple Health, and Base Layer builds a periodized program that actually responds to how your body is recovering.

HOW IT WORKS

• Set your goals: Pick your sports, set target events, describe your constraints and schedule.
• Connect your data: Base Layer reads Apple Health — heart rate, HRV, sleep, VO2 Max, workout history — so you never have to manually log anything.
• Get your program: Your AI coach builds a multi-week roadmap with progressive overload, deload weeks, and event-specific peaking.
• Train and adapt: Each week, your coach reviews your real recovery data and adjusts intensity, volume, and focus. Skip a week? Get sick? It recalibrates.

WHAT MAKES IT DIFFERENT

Your coach actually reads your data. Not just step counts — real training signals. Heart rate variability, resting heart rate trends, sleep quality, workout intensity. The program responds to what your body is telling it.

One program, everything you do. Skier who also lifts and runs? Base Layer builds one integrated plan that balances all of it, with the right energy system work at the right time.

Real periodization. Not random workouts — a structured progression with base phases, build phases, peak weeks, and recovery. Just like a human coach would design.
