How Much Exercise Do You Really Need Each Week?

With so much conflicting advice about fitness routines, it’s common to wonder: How much exercise do I actually need each week to stay healthy? The answer depends on your goals, fitness level, and lifestyle—but there are general guidelines backed by science that apply to most people.

According to the World Health Organization (WHO) and Centers for Disease Control and Prevention (CDC), adults should aim for at least:

1. 150 minutes of moderate-intensity aerobic activity per week,

or

2. 75 minutes of vigorous-intensity aerobic activity,

plus

3. Muscle-strengthening activities on two or more days per week.

Let’s break that down and see how it applies in real life.

1. Moderate-Intensity vs. Vigorous-Intensity

Moderate-intensity activities get your heart rate up but still allow you to talk. Examples include:

(a) Brisk walking

(b) Cycling at a casual pace

(d) Light swimming

(e) Gardening

Vigorous-intensity activities raise your heart rate significantly and make it hard to hold a conversation. These include:

(a) Running or jogging

(b) Fast cycling

(d) Competitive sports

You can mix and match these activities. For example, 30 minutes of brisk walking five days a week gives you the recommended 150 minutes. Or, if you prefer more intense workouts, you could do 25 minutes of running three days a week.

2. Strength Training Matters Too

In addition to cardio, muscle-strengthening activities are essential. Aim to work all major muscle groups—legs, hips, back, abdomen, chest, shoulders, and arms—at least twice a week. This can include:

(a) Weightlifting

(b) Bodyweight exercises (push-ups, squats, lunges)

(d) Pilates or yoga with strength elements

Strength training helps build lean muscle, improve bone density, boost metabolism, and support long-term mobility and balance.

3. More Benefits with More Movement

While 150 minutes per week is the minimum for general health, additional exercise brings more benefits. For greater results like weight loss, enhanced endurance, or stress reduction, aim for:

(a) 300+ minutes of moderate activity

(b) Or 150+ minutes of vigorous activity

However, balance is key. Overtraining without proper rest can lead to fatigue or injury. Make sure to include at least one rest or active recovery day per week.

4. Short Sessions Still Count

You don’t have to exercise for long stretches to benefit. Even 10- to 15-minute sessions throughout the day add up. Walking during lunch breaks, doing a quick home workout, or taking the stairs are simple ways to stay active.
