Walking is the most underrated form of exercise. It requires no equipment, no gym membership, and no special skills. But how much is it actually doing for your health and your calorie burn? This steps-to-calories calculator gives you the real numbers based on your weight, step count, and pace.

Your one-rep max — the maximum weight you can lift for a single repetition — is the gold standard for measuring strength. But testing it directly is risky and unnecessary. This calculator estimates your 1RM from a set you actually did, so you can program smarter without rolling the dice on a max lift.
