Question 1

How is 1RM estimated?

Accepted Answer

Common formulas: Epley 1RM = w*(1 + r/30) and Brzycki 1RM = w*36/(37 - r), where w is lifted weight and r reps.

Question 2

How are calories burned estimated?

Accepted Answer

We use MET values: kcal/min ~ MET * 3.5 * kg / 200; total kcal = rate * minutes.

Question 3

How do I compute running pace and speed?

Accepted Answer

Pace = time/distance; speed = distance/time. Convert between min/mi and min/km as needed.

Question 4

What is VO2 max?

Accepted Answer

An estimate of maximal oxygen uptake. Field tests (e.g., 1.5-mile run) or age-graded formulas give approximations.

Question 5

Are these medical prescriptions?

Accepted Answer

No—use them as fitness planning tools, not medical advice.
