How often should you actually work out?

Ask the internet how often you should work out and you’ll get a number designed for someone else. Five days. Six, with active recovery on the seventh. A split that assumes you’re training body parts on a rotation, which assumes you’re training often enough for a rotation to make sense, which assumes the thing you’re trying to find out.

It’s a bad answer for the person asking, because the person asking almost always means something more specific: what’s the smallest amount that’s actually worth doing? That question has a real answer, and it’s much more encouraging than the one you usually get.

Where the returns actually are

In 2022, researchers pooled sixteen prospective cohort studies to work out how muscle-strengthening activity relates to mortality and major disease, independent of aerobic exercise. The pattern they found was J-shaped, with the maximum risk reduction — roughly 10–20% — at about 30–60 minutes per week.

Thirty to sixty minutes. Per week. Not per session.

That’s two half-hour sessions, or three twenty-minute ones, or — if you’re being honest about your Tuesdays — four twelve-minute ones. And past that range, the curve doesn’t keep climbing. The “J” means the additional benefit flattens out, and the authors are careful to say the effect of higher volumes is unclear rather than clearly better.

On the aerobic side, the WHO’s global recommendation is at least 150 minutes of moderate-intensity activity per week — which sounds like a lot until you notice it includes walking, and that it’s a weekly budget rather than a daily obligation.

Put together: the dose associated with most of the health return is a couple of strength sessions and some walking. It is emphatically not a six-day split.

Why the advice is inflated

Most workout frequency advice isn’t wrong so much as aimed elsewhere. It’s written for people optimizing an outcome — a physique, a lift, a race — where the question genuinely is “what’s the most productive volume I can recover from?” For that person, more is often better, and the advice reflects it.

But if you’re asking how often you should work out, you’re usually not that person yet. You’re trying to find a frequency that survives contact with your actual life. And for that, the meaningful variable isn’t the one being optimized in those articles.

Here’s the arithmetic that gets skipped. A four-day-a-week plan you hold for three weeks is twelve sessions. A two-day-a-week plan you hold for six months is about fifty. The second plan is “worse” by every standard the internet measures and roughly four times more training.

Frequency you can’t sustain isn’t a higher dose. It’s a shorter program.

So what should you pick?

A reasonable starting point, and the one the evidence above supports without heroics:

• Two strength sessions a week, somewhere in the 20–30 minute range. That lands you inside the 30–60 minute window where the returns concentrate.
• Walking on top, accumulated however it happens — commutes, errands, a phone call on your feet. The 150 minutes is a budget, not a workout.
• A third session when the week allows it. Not a requirement. A bonus that costs nothing when it doesn’t happen.

If that feels like too little to bother with, that reaction is worth examining, because it’s the thing that ends most training. The belief that a small amount isn’t worth doing is what converts a busy week into a skipped one, and skipped weeks into a stopped habit. The research says the small amount is where most of the benefit lives.

And if two sessions is currently too many — genuinely, given this season of your life — then the honest answer is one. One a week, held, beats three a week abandoned in two weeks. You can always add the second once the first is automatic.

The frequency question is really a scheduling question

Notice what happens when you settle on two: you’ve turned an open-ended obligation (“work out more”) into a small, bounded, schedulable thing. That’s most of the benefit of asking the question in the first place.

What usually breaks next isn’t the number — it’s that the two sessions have no shape. They’re not attached to particular days, and the session itself has to be invented each time, which is the part people actually stall on.

This is where an app earns its place, and it’s the thing we built Coax around. You tell it how many days a week you’re aiming for during setup, and it lays that out as a week you can see — with today’s session already built and waiting behind a single Start today’s session card. Two days a week is a perfectly normal answer to give it; nothing in the app pushes you toward more, and the streak counts weeks you trained rather than days, so a two-day week is a complete week.

The daily check-in then sizes whatever you’re doing today to the time you actually have — ten, twenty, thirty, forty-five minutes — so “my two sessions” doesn’t have to mean the same two sessions regardless of how the week is going. A twenty-minute Tuesday still counts. So does a ten-minute one.

It’s free to start, in beta, and there’s a demo you can look at without signing up, if you’d rather see what a two-day week looks like before committing to anything.

The short version

How often should you work out? Two strength sessions a week, plus walking, puts you in the range where most of the measurable health return sits. Three is good. Six is a hobby, not a requirement.

Is twice a week enough? For health outcomes, the evidence says it’s most of the way there. For a specific athletic goal, you’ll want more — but you’ll also want a coach and a program, which is a different question than this one.

What if I can only manage once? Then do once. The gap between zero and one is the largest gap in this entire article. Every other increment is smaller than that one.

The number you’re looking for isn’t the one that sounds impressive. It’s the one still happening in March. Pick that one, and let the good weeks be better than planned — smaller starts are the ones that survive.
