Workout Consistency Calculator

Three sessions a week is 156 a year, and that is the whole argument for consistency. Enter your routine and this totals the sessions, the hours and the calories at 30 days, 90 days, six months, one year and two — calories from the standard MET equation, using the published value for your activity.

How the totals are calculated

Sessions are frequency times weeks, and the weeks are the honest number rather than a round one: a year is treated as 52.14 weeks, thirty days as 4.29, ninety as 12.86, six months as 26.07 and two years as 104.29. Three sessions a week for a year is therefore 156 sessions rather than 156 exactly by luck. Hours are sessions times the session length you set, and the days figure below it is those hours over 24.

Calories use the standard MET equation: METs times body weight in kilograms times duration in hours. The MET values are the published Compendium figures for each activity — running 9.8, HIIT 8.0, cycling 7.5, strength training 6.0, walking 3.8, yoga 3.0 — and a 75 kg person running for 45 minutes therefore burns about 551 calories on this arithmetic. What the equation cannot do is know your body: METs are population averages for an activity at a given intensity, they take no account of fitness, efficiency or how hard you actually worked, and the resting rate they are multiples of varies between people. Treat any single session's figure as a rough one and the comparison between activities as the useful part. The marathon comparison divides your total by 2,600 calories, which is our round figure for running one.

Nothing here is a health claim. Every figure is arithmetic on the numbers you typed, and the whole point of the page is the multiplication rather than the physiology: three sessions a week does not feel like much, and 156 of them is a different sentence.

Nothing on this site is medically reviewed. Every figure above was read out of the code that runs on this page, and where a number is our own judgement rather than a published one, the note says so and cites nothing. Method last checked 21 August 2026.

Why consistency beats intensity

Consistency is the single most underrated factor in fitness. People obsess over the perfect workout program, the optimal rep scheme, the ideal diet — but the most effective workout is the one you actually do, repeatedly, for months and years.

The math of consistency is staggering. Three workouts per week doesn't sound like much. But over a year, that's 156 sessions. Over five years, 780 sessions. Each one building on the last, creating compound adaptations in strength, endurance, and health that no short-term program can match.

Most people quit by week three. They start too hard, get sore, skip a session, feel guilty, and abandon the habit entirely. The secret is starting easy enough that consistency is almost guaranteed, then gradually increasing over time.

This calculator exists to show you the power of what you've already built — and what's ahead if you keep going. When you can see that another year of 3x/week training adds up to 156 more sessions and thousands of calories burned, the motivation to protect your streak becomes concrete.

Frequently Asked Questions

How many workouts per week is ideal?

The WHO recommends at least 150 minutes of moderate aerobic activity or 75 minutes of vigorous activity per week, plus strength training 2+ days. For most people, 3-5 workouts per week is a sustainable sweet spot that delivers significant health benefits.

How are calorie estimates calculated?

Calorie estimates use MET (Metabolic Equivalent of Task) values for each activity type, multiplied by your body weight and session duration. These are estimates — actual calorie burn varies based on intensity, fitness level, and individual metabolism.

What's the marathon equivalent?

The marathon equivalent converts your total calorie burn into the number of marathons worth of energy expenditure. An average marathon burns approximately 2,600 calories, though this varies significantly by body weight and pace.

Why does consistency matter more than intensity?

Research consistently shows that workout frequency (showing up regularly) predicts long-term fitness outcomes better than workout intensity. Three moderate sessions per week for a year beats six intense sessions per week for a month.
