Periodized Training Plans

Build structured training schedules using periodization principles. Organize your training across base, build, peak, and taper phases for optimal race preparation.

📝

Daily Training Log

Record every swim, bike, and run session with detailed metrics including distance, duration, heart rate, RPE, and custom notes. Track your progress over time.

📊

Performance Analytics

Visualize training load, intensity distribution, and fitness trends with interactive charts. Monitor your training stress score (TSS) and weekly volume.

❤️

Seiler HR Zone Calculator

Calculate heart rate training zones using Dr. Stephen Seiler's 3-zone model based on ventilatory thresholds (VT1/VT2). Supports both %HRmax and Karvonen methods.

💤

Recovery Guide

Monitor recovery status with sleep quality tracking, fatigue indicators, and readiness scores. Get science-based recovery recommendations between sessions.

🗓️

Periodization Calendar

Visualize your entire training plan on an interactive calendar. Plan mesocycles, manage training load progression, and schedule race events.

Evidence-Based Training

FIT-DB is built on peer-reviewed sports science research. Our training intensity distribution model follows the polarized training approach advocated by leading exercise physiologists.

The heart rate zone calculator implements Dr. Stephen Seiler's 3-zone intensity model based on ventilatory threshold markers, validated across endurance disciplines including swimming, cycling, and running.
