How Much Cardio Per Week to Lose Weight? A Range

To lose weight, most adults do best with 150 to 300 minutes of moderate cardio a week, paired with a modest calorie deficit and two days of strength work. The 150 minute floor matches the federal physical activity guidelines for general health, and the higher end is where studies commonly see more reliable fat loss. Treat it as a range to move through, not a target to hit on day one. For a plan tied to your own numbers, see the weight loss coaching page.

Find your point in the range

The right number depends on where you start and how much food change you are making:

Starting point	Weekly cardio to aim for
Mostly inactive, new to exercise	90 to 150 minutes, built up over a month
Moderately active, eating in a small deficit	150 to 225 minutes
Active but stalled	225 to 300 minutes, or add intensity
Already above 300 and stuck	Fix food and lifting before adding more

Moderate effort means breathing is up, you can speak in sentences and you could keep going for an hour. Break it into three to five sessions of 30 to 60 minutes, or into 10 minute chunks if that is what the day allows.

Add minutes the way you add weight

Make one change at a time. Add 15 to 30 minutes every two weeks, watch your weight trend, waist and energy for a fortnight, and stop adding when the trend turns the right way. If energy sinks, sleep suffers or hunger overwhelms your plan, you went up too fast.

Why more is not always more

Cardio has diminishing returns for weight loss. The body adapts by trimming other daily movement and appetite creeps up, so the net gain from the tenth hour is far smaller than the net gain from the third. Muscle kept through lifting, which you can see in cardio versus weights, usually moves the result more than another hour on a bike.

If you are exercising within range and not losing, look at food logging, sleep and stress before you add minutes. Our page on a plateau after three months lists those checks in order.

Walking counts

Steady walking is the most sustainable way to build the base. A daily 40 minute walk is 280 minutes a week, which already sits inside the range, and our look at whether walking is enough exercise covers its limits. Add a couple of effort-based sessions only after the walking habit is stable.

What the minutes should feel like

Most of your weekly total should sit at an easy to moderate effort, where breathing is up but you can still speak in full sentences. A small slice can be harder, such as one interval session, since variety keeps the work interesting and lifts fitness. If every session feels like a punishment, the plan is too aggressive for your current fitness and will not last. Choose activities you can repeat on a tired Thursday, because the weeks you actually do the minutes matter more than the perfect week you only planned.

Check with a professional if

Anyone with heart disease, high blood pressure, diabetes or long inactivity should ask a physician what intensity is appropriate before raising minutes. After that, a coach can set the weekly number around your scan, your joints and your calendar. FlexWerk coaches in Carmel work on their own terms, and the free consultation with an InBody scan is the way to begin.
