Sport & Fitness Calculators for Athletes
Track your fitness progress without expensive apps. Plan training routines, generate parkour combinations, measure vertical jump, and calculate performance metrics — all private, all free, all in your browser.
Take your training to the next level with specialized tools for athletes. From generating parkour combinations to tracking performance, we provide the utilities you need to reach your peak potential.

Calculate Your FFMI
Calculate your Fat-Free Mass Index with normalized height adjustment and natural limit overlay.
HIIT Workout Timer
Customizable High-Intensity Interval Training timer for any workout routine.
Intermittent Hypoxia Breathing Timer
Guided breathing exercise timer with configurable rounds of rapid breathing, breath holds, and recovery periods.
Macro Split Generator
Calculate your ideal macronutrient split based on your daily calorie goal and fitness objectives.
1-Rep Max Calculator
Calculate your estimated one-repetition maximum (1RM) using various established formulas.
Parkour Combo Generator
Generate random and creative parkour combinations and sequences to practice.
Plate Loading Calculator

Running Pace Calculator
Calculate your pace, time, or distance for your runs and races.
Check Your Strength Standards
Check your powerlifting strength level with Wilks, DOTS, and IPF GL scoring across squat, bench, deadlift, and OHP.
Tabata Timer
High-intensity interval training (HIIT) timer with customizable work and rest periods.
Vertical Jump Meter
Estimate your vertical jump height from air time using physics-based calculation.
Estimate Your VO2 Max
Estimate your VO2 max using Cooper, Rockport, or Uth formulas with fitness age and ACSM percentile ranking.

Select your sport or metric
Vertical jump analysis, parkour combinations, pace calculators, one-rep max estimators: each tool targets a specific athletic measurement. Choose the one that matches your training focus.
Enter your performance data
Height, weight, time, distance, reps, load: fill in the fields that apply. Units can be toggled between metric and imperial. Be honest with your numbers; inflated inputs produce useless results.
Read the analysis
Results include the calculated metric plus contextual benchmarks. Where applicable, the tool tells you how your number compares to average, intermediate, and elite levels for your demographic.
Plan your training
Use the results to set realistic targets. Come back after a training cycle and re-test to measure progress. The tools do not store historical data so keep a log externally.
Athletes Tracking Progress
Vertical jump height, one-rep max, pace per kilometer: these numbers tell you whether your training is working. Our calculators use validated formulas so the results are comparable over time. Test, train, re-test; the data does not lie.
Coaches Planning Programs
When you need to estimate a client's max based on their submaximal performance, our calculators apply standard equations like Epley and Brzycki. Use the results to program percentages-based training without requiring a maximal test every cycle.
Parkour Practitioners Looking for Inspiration
The combo generator creates random movement sequences based on skill level and available obstacles. It forces you out of your comfort zone and into combinations you would not have tried on your own. A creative tool disguised as a calculator.

Yes; all calculators are free with no sign-up.
Completely. Your body measurements, performance numbers, and training data are processed in your browser and never sent to any server.
Each tool states its formula. One-rep max calculators offer Epley, Brzycki, and Lombardi equations. Vertical jump analysis uses validated biomechanical models. The formulas are standard in exercise science literature.
Yes. The tools are useful for quick assessments. However, always combine calculator results with your professional judgment and direct observation of the athlete.
Estimates based on submaximal reps are generally accurate within 5-10% for trained individuals. The accuracy decreases with higher rep counts (above 10 reps) and for untrained individuals whose neural efficiency changes rapidly.
Some do. Relative strength calculators normalize your lift by body weight. Absolute strength tools give the raw number. Check the specific tool to see which approach it uses.
The tools do not store history. Log your results in a training journal or spreadsheet. Consistent tracking over weeks and months is more valuable than any single measurement.
