TRAININGHARDCORE
Train hard, train smart — strength, conditioning, and the calculators behind every rep.
From estimating your one-rep max and analyzing body composition to dialing in your macros, planning a training split, tracking recovery, and benchmarking your strength, TrainingHardcore pairs free hands-on fitness calculators with practical guides and a richly illustrated museum. Train hard, train smart.
Fitness Tools & Calculators
Free tools for every lifter and athlete — one-rep max calculator, body composition analyzer, macronutrient calculator, heart rate zones, workout volume, strength standards, and a training split generator. General fitness estimates, not medical advice.
One-Rep Max Calculator
Estimate your one-rep max from a weight you can lift for a few reps — Epley and Brzycki formulas plus a full training-percentage table for programming your sets
BMI & Body Composition Analyzer
Calculate your body mass index from height and weight, see your category, and put the number in context for lifters and athletes — a screening figure, not a verdict
Body Fat Calculator
Estimate your body-fat percentage with the U.S. Navy tape method, see your category, and get your fat mass and lean mass — a practical, no-calipers estimate
Macronutrient Calculator
Turn your daily calorie target and goal into protein, carb, and fat targets in grams — dial in macros for cutting, maintaining, or building muscle
Calorie Burn Calculator
Estimate the calories you burn in a workout from the activity, your bodyweight, and the duration using MET values — compare exercises and plan your energy balance
Heart Rate Zone Calculator
Find your five training heart-rate zones from your age — and optionally your resting heart rate — to train recovery, endurance, tempo, and VO2 max on purpose
Workout Volume Calculator
Total your training volume across a session — load times reps for every exercise, plus total working sets and reps — the core metric for progressive overload
Body Measurement Tracker
Log your chest, waist, hips, arm, and thigh measurements, total them, and get your waist-to-hip ratio — track real shape changes the scale can't show
Recovery Time Calculator
Estimate how long a muscle group needs before its next hard session, scaling a baseline by muscle size, session intensity, and your training experience
Strength Standards Checker
Rate your squat, bench, or deadlift against bodyweight-multiple standards by sex — see your level from untrained to elite and what earns the next tier
Training Split Generator
Build a weekly training split from your available days and goal — full body, upper/lower, or push/pull/legs — with a day-by-day schedule and a programming note
Flexibility Assessment Tool
Rate your sit-and-reach result against standard thresholds adjusted by sex, from poor to excellent, with a note and a recommendation to improve mobility
Muscles & Movement Museum
Walk an immersive museum of the anatomy and training that shape the way we move — the major muscle groups and how they fire alongside the compound lifts that build them, the world of strength and hypertrophy, HIIT and conditioning, nutrition and macros, and the art of programming and recovery, each in its own gallery, so you can get to know the story behind every rep: how each system adapts, what makes it matter, and the role it plays in building a stronger, more capable body.
