About

100 Days to Fit is a science-based fitness program built for people who want real, personalized results — not generic workout plans.

Rather than one-size-fits-all routines, 100 Days to Fit calculates your unique baseline using your body metrics and current fitness level, then builds a fully personalized 14-week periodized program around it — covering strength training, cardio, mobility, and nutrition.

HOW IT WORKS - Measure — Enter your body metrics (age, height, weight, and primary goal) to establish your baseline. - Test — Complete a PAR-Q health screening and baseline strength/cardio testing (sample lifts and a 5KM time) to calibrate your personalized targets. - Start — Instantly see your calculated BMR, TDEE, calorie targets, and heart rate zones — all built from your own data.

FULL PROGRAM FEATURES - A complete 14-week periodized strength and cardio schedule, structured week by week - A macro-based nutrition system with calorie targets and recipe/meal prep guidance - Mobility protocols to support recovery and long-term movement health - Progress tracking to log workouts and monitor results over time - Clear, animated exercise demonstrations for proper form on every movement

DESIGNED WITH A STOIC MINDSET 100 Days to Fit pairs its training system with Stoic philosophy for motivation — helping you build discipline and consistency, not just chase short-term results.
