Build Muscle Without Guesswork BYLD is a hypertrophy-focused workout tracker that shows how much effective training each muscle gets and how it compares with personalized weekly targets. Log your workouts, track your progress, and see where your training stands — so you can spend your effort where it matters. Know What Each Muscle Needs BYLD goes beyond counting workouts and raw sets. • Track weekly training for individual muscles • See personalized muscle targets based on your training level and goals • Measure training using effective sets, not just total sets • Account for exercise muscle contribution and training effort • See which muscles need more work and which are already covered • Explore exactly which workouts, exercises, and sets contributed to each muscle • Visualize your weekly muscle coverage on an interactive body map • Review previous weeks and monitor your consistency over time Track Every Workout Everything you need for day-to-day gym tracking: • Log sets, reps, weight, and optional RIR • Create and edit your own workout routines • Start a workout from a routine or from scratch • Add, replace, remove, and reorder exercises while you train • Edit sets at any point during your workout • Resume an active workout whenever you come back • Review and edit your workout history See Your Progress Keep track of how your training is evolving. • Follow your weekly and monthly workout activity • Track training volume, reps, and workout duration • View progress by muscle group and individual exercise • See your previous performance before your next set • Jump directly from exercise history into past workouts Train Your Way • Browse exercises by muscle and equipment • Watch exercise demonstration videos • Use metric or imperial units • Build routines around the exercises and equipment you prefer • Train with a clean, distraction-free interface BYLD is designed for lifters who want more than a workout log — and want to know whether their training is actually aligned with their muscle-growth goals.
