Key Terminology

BMR (Basal Metabolic Rate)

Calories burned at complete rest to sustain vital functions. Calculated via the Mifflin-St Jeor equation (most accurate for the general population).

TDEE (Total Daily Energy Expenditure)

BMR multiplied by an activity factor (1.2–1.9). Your total daily caloric requirement for body weight maintenance.

1RM (One Rep Maximum)

Maximum weight liftable for a single repetition. Used to calculate training percentages: 65–80% for hypertrophy, 85–95% for strength.

Heart Rate Reserve (HRR)

Difference between maximum and resting heart rate. Used in the Karvonen formula for calculating precise training zones.

VO2 Max

Maximum oxygen utilization per minute per kg of body weight. Declines ~1%/year after age 25 without training; trainable through structured aerobic exercise.

Progressive Overload

Gradually increasing training stimulus (weight, reps, or sets) by 2.5–5% when all target reps are completed. The fundamental driver of adaptation.

Body Composition

The ratio of fat mass to lean mass. More informative than BMI for athletes — a 90kg athlete with 10% body fat is categorically different from a 90kg sedentary individual.

Frequently Asked Questions

Q1 How do I calculate my TDEE accurately?

Multiply your BMR by your activity multiplier: Sedentary (1.2), Light exercise 1–3 days/week (1.375), Moderate 3–5 days/week (1.55), Hard 6–7 days/week (1.725), Physical job + training (1.9). Endurance athletes often need the 1.725–1.9 range.

Q2 What percentage of 1RM should I use for hypertrophy?

65–80% of your 1RM, for 8–12 reps per set, with 60–90 seconds rest between sets. This rep range creates optimal mechanical tension and metabolic stress for muscle growth according to NSCA guidelines.

Q3 How do I find my maximum heart rate accurately?

The most accurate method is a graded exercise test to exhaustion. Field tests (sprint finish of a 5K race) approximate this. The 220-age formula carries ±10–12 BPM error — use the Tanaka formula (211 − 0.64 × age) for endurance athletes.

Q4 Is BMI an accurate measure of health?

BMI is a population-level screening tool, not an individual health assessment. It does not account for body composition, muscle mass, or fat distribution. A muscular athlete may have an 'overweight' BMI with excellent health markers. Waist circumference and body fat % provide more individual insight.

Laboratory Insight: Specialized advanced metrics from the Human Optimization Wing provide a superior baseline for your training goals. NSCA hypertrophy guidelines: 65–80% of 1RM, 8–12 reps per set, 3–4 sets per exercise, 60–90 second rest intervals.

Key Performance Benchmarks

Scientific Verification

Use Cases / Example Scenarios

Body Composition Audit

Scenario

Use BMI alongside waist circumference and body fat % for a complete cardiovascular risk picture that BMI alone cannot provide.

Metabolic Rate Troubleshooting

Scenario

If weight loss has stalled, recalculate your BMR with current body weight and activity level — metabolic adaptation reduces TDEE by 5–10% over time.

Cutting Phase Planning

Scenario

Calculate your TDEE and set a 15–20% caloric deficit to trigger fat loss while preserving lean muscle mass.

Strength Program Design

Scenario

Use 1RM-derived percentages to program your squat, bench, and deadlift with scientifically-validated rep schemes for your goal (strength vs hypertrophy).
