25,000-word guide covering everything from client assessment to business pricing. BMI interpretation, TDEE programming, macro calculation, 1RM methodology and more.
Personal trainers and fitness coaches spend hours on calculations that should take seconds. How much should a client eat? What is their body fat percentage? How many calories did they burn in today's session? What weight should they use for their sets this week? These calculations are critical — and doing them manually is error-prone and slow.
ToolsCourt's fitness tool library gives every trainer — from solo online coaches to gym professionals — a complete set of professional-grade calculation tools, completely free. No account. No subscription. No app to install. Every tool runs in your browser and works on any device including mobile.
The BMI calculator and body fat percentage estimator give trainers a complete picture of a new client's starting point during onboarding. The body fat estimator uses the US Navy method — requiring only a tape measure, no expensive calipers or DEXA scan needed. Together these two tools give trainers the baseline data for every client assessment.
The TDEE calculator uses the Mifflin-St Jeor formula — the most validated BMR equation for most adults — and applies activity multipliers to estimate real-world calorie needs. The macro calculator then breaks those calories into protein, carbohydrate and fat targets based on the client's goal: fat loss, muscle gain, maintenance, keto or endurance performance. The calorie burn calculator covers 40+ exercises using validated MET values from the Compendium of Physical Activities.
The one rep max calculator is the foundation of percentage-based strength programming. It calculates estimated 1RM from any submaximal set using all 7 major formulas (Epley, Brzycki, Lander, Lombardi, Mayhew, O'Conner, Wathan) and shows the average — the most reliable estimate. The included percentage chart shows exact training weights from 50% to 100% of 1RM for every major training goal, ready to use in the workout plan builder.
Running a personal training business requires more than fitness knowledge. The coaching rate calculator helps trainers price their services correctly — based on income goals, business expenses, experience level, location and delivery method. It generates ready-to-use package pricing at 4-session, 8-session and monthly levels. The fitness assessment form generator produces professional client intake forms with PAR-Q screening, medical history, goals assessment and liability consent — downloadable as a print-ready HTML file.
The client progress tracker enables weekly check-ins tracking weight, body fat, waist circumference, energy level and sleep. Data is saved in the browser — no account required — and can be exported as CSV. Trainers with up to 4 clients can use the tracker completely free. The tool includes a waitlist for the upcoming Pro version with multi-client support, permanent cloud storage and progress charts.
