Estimate body fat with U.S. Navy and BMI formulas. Switch units, get body fat category, fat mass, and lean mass in seconds.

Estimate your VO2 max using popular run, walk, and heart rate methods. Fast results, unit conversions, and fitness ratings in one simple tool.

Estimate your BMR and daily calorie needs with metric or imperial units using Mifflin-St Jeor or Harris-Benedict.

Why the scale stalls despite exercise: metabolic adaptation, drops in NEAT, rising appetite, and how resistance or mixed training can help.

Smartwatch VO2 max is useful for long-term trends; lab CPET provides precise VO2, ventilatory thresholds, and clinical-grade results.

VO2 max is the single best marker of cardiorespiratory reserve—age, sex, training, and body composition determine what 'good' means.

Healthy body fat ranges by sex, age, and activity, measurement methods, risks, and practical steps to reach safe targets.

Higher VO2 max cuts mortality risk—small improvements in cardiorespiratory fitness lower death from heart disease, cancer, and all causes.

DEXA provides precise, low-radiation body-composition tracking to detect meaningful muscle changes and known measurement limits.

Balance Zone 2 aerobic work with Zones 4–5 intervals (80/20) to boost VO2 Max 5–20% in 8–12 weeks; set zones with tests, wearables, or RPE.

Estimate your TDEE, set a deficit or surplus for your goals, and fine‑tune intake with tracking or metabolic testing.

How low-intensity Zone 2 runs build aerobic capacity, fat-burning and recovery to make you faster over weeks and months.

Heart rate zones let you train smarter—calculate your MHR, set Zones 1–5, and tailor workouts for fat loss, endurance, or speed.

Eat near maintenance, prioritize protein, and follow strength training plus measured cardio to lose fat and build muscle steadily.

Tailor DEXA timing to your goals: annual bone-density checks by T‑score and risk, and body-composition scans every 3–6 months.

Step-by-step checklist to prep for metabolic and RMR tests: fasting, hydration, meds, exercise limits, and timing for accurate results.

Early DEXA screening, nutrition, and strength training can detect and improve low bone density before fractures occur.

How VO2 Max changes with age, plus age-and-sex benchmarks, testing options, and proven training to boost cardiovascular fitness.

Explains DEXA measurements—body fat distribution, lean mass, visceral fat, RMR, and bone density for practical health insight.

Persistent fatigue, cravings, or unexplained weight shifts often mean your metabolism needs testing before bigger problems arise.

Compare five body composition tests—DEXA, BIA, calipers, hydrostatic weighing, and 3D scans—by accuracy, cost, and best use.

Rest, hydrate, eat carbs, sleep well and wear light gear—practical steps to perform your best on a lab VO2 max test.

Compare DEXA scans and body-fat scales — accuracy, cost, pros, and when to choose each for reliable body-composition tracking.

Judging your health by your body weight might actually make you less healthy.

Why bone density matters and how to measure it with a DEXA.
