If you’re asking how much exercise you actually need each day, the short answer is: most adults need about 150 to 300 minutes of moderate-intensity activity a week – roughly 20 to 40 minutes a day – or 75 to 150 minutes of vigorous exercise a week, plus muscle-strengthening activity on two or more days. The exact amount that’s ideal for you depends on your current fitness level, health goals, and any existing health conditions.
This guide breaks down what these guidelines mean in daily terms, how to turn them into a realistic workout routine, and how much exercise is recommended depending on whether you’re aiming for general health, weight loss, or a specific fitness goal.

Health authorities, including the World Health Organization (WHO), the US CDC, and Singapore’s Health Promotion Board (HPB) and Sport Singapore, generally agree on the same baseline. Adults aged 19 to 64 should get:
If you prefer to think in terms of daily exercise, 150 minutes a week works out to about 30 minutes a day, 5 days a week. If you’re doing vigorous exercise instead, that’s closer to 15 to 20 minutes a day.
Singapore’s revised Physical Activity Guidelines (SPAG) no longer set a strict minimum session length. Instead of needing to hit a fixed number of minutes each time you exercise, what matters most is the total amount you accumulate across the week – so a few shorter sessions spread across the day can count just as much as one longer one.

Once you know the weekly target, the next question is usually how much workout you should actually be doing in a day to get there. There’s no single correct answer, but here are a few realistic ways to structure it:
A sample weekly structure that meets the guidelines might look like this:
Monday: 30min – Moderate cardio (brisk walk, cycling)
Tuesday: 20-30min – Strength training (major muscle groups)
Wednesday: 30min – Moderate cardio or active rest
Thursday: 20-30min – Strength training
Friday: 20-30min – Moderate or vigorous cardio
Saturday: 30-45min – Longer activity of choice (hike, sport, swim)
Sunday: Optional – Rest or light movement
You don’t need a gym or formal “workout” every day to hit this. Daily activity such as brisk walking to the MRT, taking the stairs, or an active household chore all contribute to your weekly total – a structured workout session is simply one way to accumulate the minutes more efficiently.
The recommended amount of daily exercise isn’t identical for everyone. It generally shifts depending on what you’re trying to achieve:

You may have also come across the “10,000 steps a day” target. This number wasn’t originally based on clinical research – it came from a 1960s marketing campaign in Japan. More recent studies suggest that benefits, including a lower risk of early death, can already be seen at around 7,000 steps a day, with further increases offering diminishing additional benefits.
Steps and minutes aren’t competing targets – they’re two ways of measuring the same thing: how much you’re moving. If counting steps is easier for you to track day to day, use it as a rough guide, but don’t feel you must hit exactly 10,000 if you’re already meeting the moderate or vigorous activity guidelines above.

Knowing the numbers is one thing – building the habit is another. A few practical ways to close the gap:
If you’re just starting out, there’s no need to jump straight to 30 minutes a day. Begin with 10–15 minutes of light-to-moderate activity, such as walking, and gradually build up duration and intensity over a few weeks as your fitness improves.
There’s no single cut-off that applies to everyone, but signs you may be doing too much include persistent fatigue, disrupted sleep, ongoing muscle soreness, or a drop in performance rather than improvement. If this happens, it may be worth scaling back and allowing more recovery time between sessions.
Yes. Current guidelines no longer require one continuous block of exercise. Two or three shorter sessions across the day – for example, three 10-minute walks – can count toward your weekly total in the same way as one longer session.
Weight loss generally requires more activity than the baseline guidelines for general health – often up to 300 minutes or more of moderate exercise a week, alongside strength training and dietary changes. The right amount for you also depends on your starting weight, activity level, and overall calorie balance.
For most adults, 30 minutes of moderate activity most days of the week meets the general health guidelines of 150 minutes a week. Whether it’s “enough” for you specifically depends on your goals — it’s a solid baseline for general health, though weight loss or performance goals may call for more.
Older adults are generally encouraged to work toward the same 150–300 minutes a week as other adults, along with muscle-strengthening and balance activities, adjusted to individual ability and any existing health conditions. Some activity is better than none, so it’s fine to start gradually and build up over time.

Most adults should aim for 150–300 minutes of moderate exercise (or 75–150 minutes of vigorous exercise) a week, plus strength training twice a week – roughly 20–40 minutes of daily activity. The right amount for you depends on your goals, current fitness, and any health conditions, so it’s worth adjusting the guidelines to fit your own situation.
