FormBase

Train deliberately. FormBase builds your strength and running programs from the data you actually have: your tested 1RMs, your observed pace zones, your real HR signals. Every prescription is deterministic. Every recommendation has a readable rule. STRENGTH • Programs calibrated to your tested 1RM, bodyweight, and tier: Untrained to Elite • Phase blocks with explicit progression, no black box • Per-muscle volume, hard sets per week, plateau detection • Strength Score with percentile by lift • Body flags reshape the program around injuries automatically RUNNING • Z2 / Z3 / Z4 / Z5 zones from your actual HR + pace • Race goals: sub-2 half, sub-25 5K, sub-4 marathon, sub-90 10K, and more • Decision engine reads resting HR, post-run feedback, training load • Adaptive prompts catch Z2 stall, HR creep, and volume spikes early • Threshold detection by HR zone, not guesswork HYROX • 1 km pace projection from your observed Z3 • Per-station benchmarks and PB tracking • Finish-time forecast against your target STRAVA • One tap to connect, runs auto-import with HR, splits, route map • Per-run analyzer: pace, HR, elevation, time-in-zone, grade-adjusted pace, plateau disclosure • All processing is deterministic: no ML models on your data, no cross-user analytics COACHING • Browse independent coaches by modality • Contact directly off-platform.
