Practical fitness estimates to help you make informed decisions. No account required, and your entries stay in your browser.

Daily Calorie & TDEE Calculator

Estimate your resting energy needs and the calories required to maintain your current weight.

Uses the Mifflin–St Jeor equation with standard activity multipliers. Activity factors are rough estimates, and real maintenance needs can differ substantially. The deficit example is not a personalized prescription, especially for people with medical conditions or unusually low calorie needs.

Body Fat Percentage Estimate

Use a measuring tape to estimate body fat using the U.S. Navy circumference method. Measure consistently and avoid pulling the tape tight.

For the male equation, measure the abdomen at the navel, and the neck just below the larynx.

The U.S. Navy circumference equation can be inaccurate for some body types and is particularly limited by loose skin, body-fat distribution, and measurement technique. Do not treat small changes as proof of fat gain or loss. For more reliable trends, use the same measurement locations and conditions each time.

Custom Calorie & Macronutrient Planner

Start with your estimated maintenance calories (TDEE), choose a weekly weight-change goal, and customize your protein, fat, and carbohydrate percentages. All three percentages must total 100%.

Use your result from the Calories & TDEE tab, or enter your own estimate.
100%Ready to calculate
Weekly weight change is an approximation based on 3,500 calories per pound (500 calories/day per 1 lb/week). Real results vary with metabolism, body composition, water changes, adherence, and adaptive changes in expenditure. A 1,000-calorie daily deficit or surplus is not suitable for everyone, and a 2 lb/week gain will not necessarily be muscle. Macro percentages are user-selected, not individualized recommendations. Very low calorie targets, certain medical conditions, pregnancy, and eating-disorder history warrant individualized professional guidance.

Fitness Calculators & Measurement Tools

Choose a calculator below. These estimates are educational and are not medical advice.

Weight-Loss Timeline
Simple planning projection; actual weight change often slows and varies.
One-Rep Max & Training Loads
Epley estimate; less reliable at high repetitions or for unfamiliar lifts.
Waist-to-Height Ratio
Waist circumference reflects central size but does not diagnose health or distinguish loose skin.
Heart Rate Training Zones
Age-predicted maximum heart rate and training zones are approximate; medications can alter heart-rate response.
BMI Calculator
BMI is a screening measure, not a body-fat measurement; muscularity and body composition matter.
Lean Body Mass Estimate
Depends entirely on the accuracy of the body-fat estimate.
Protein Needs Calculator
Common active-adult targets often fall around 1.2–2.0 g/kg/day. Individual needs vary; higher body weights may warrant goal-weight or lean-mass based planning.
Walking Energy Estimate
Approximate gross exercise energy using a level-ground walking equation; terrain and individual economy change results.
Walking / Running Pace
Average pace across the whole session, including stops.
Hydration Planning
General fluid planning only. Drink according to thirst and conditions; avoid forcing large volumes of water.
Calorie Deficit / Surplus
Uses the 3,500 kcal/lb planning shortcut, not a guaranteed outcome.
Strength Progress
Compares estimated 1RM using the same formula; technique and effort influence comparisons.
Resting Metabolic Rate
Mifflin–St Jeor estimate. Resting expenditure is not your total daily calorie need.
Barbell Plate Loader
Assumes matching plates on both sides; available plates: 45, 35, 25, 10, 5, 2.5 lb.
Phoenix Transformation Report — Before & After PDF

Phoenix Training · Interactive Learning Center

Plan. Learn. Track.

More than quick calculations: build practical plans, compare real progress, and take a printable copy with you. Tools run in your browser. Export records if you want to keep them.

1 · Starting-Point Fitness Assessment

Get a realistic starting framework based on your experience, schedule, and equipment. This is not a diagnosis or medical clearance.

2 · Workout Program Builder

Generate a structured starter week with sets, reps, rest, and progression guidance. Your weekly split adjusts automatically to your available training days.

Important: A generated workout does not replace instruction from a qualified trainer on proper form. Thoroughly research and learn correct exercise technique before beginning any workout. If you are unsure about a movement, seek hands-on guidance rather than guessing.

3 · Long-Term Progress Dashboard

Log dated measurements and see trends over time. Save a JSON backup to your device and import it later. Records are not stored on a Phoenix Training server.

Your current entries are held in this page's memory until you refresh or close it. Export a backup to retain them. Body fat estimates are not direct measurements of muscle.

4 · Exercise Library

Choose your available equipment first, then select the muscle group you want to train. Matching exercises and their illustrations appear automatically, alongside technique reminders and easier alternatives.

Technique and safety: Viewing an exercise or workout does not replace instruction from a qualified trainer. Thoroughly research proper form before attempting unfamiliar movements. Start with manageable resistance, use safe equipment setups, and seek hands-on guidance when uncertain.

Select your equipment to begin.

5 · Personalized Fitness Roadmap

Build an achievable 4-, 8-, or 12-week habit and training roadmap, without promising a particular weight change.

6 · Fitness Knowledge Center

Concise lessons that help you interpret the tools, plus a short knowledge check.

BMR vs. TDEE

BMR estimates resting energy use. TDEE estimates your total daily expenditure, including movement and digestion. Both are estimates, best calibrated against real trends.

Progressive overload

Gradually increase reps, load, range of motion, or quality while maintaining technique. Progress does not require maximal effort every session.

Protein & recovery

Protein supports tissue repair and muscle adaptation. Adequate sleep, total food intake, and recovery also matter. Individual needs differ.

Understanding body composition

Bioimpedance readings can shift with hydration, exercise, and testing conditions. Compare trends with consistent methods rather than interpreting one scan as proof of muscle gain or loss.

Cardio intensity

The talk test is a practical guide: moderate effort usually permits conversation; vigorous effort makes full sentences difficult. Heart-rate formulas are approximations.

Educational tools only. For pain, significant medical conditions, pregnancy, eating-disorder concerns, or uncertainty about safe exercise, seek appropriate professional guidance. These tools do not replace individualized assessment.
