To maintain basic health and reduce the risk of chronic disease, the NHS and World Health Organisation recommend that adults aged 19 to 64 complete at least 150 minutes of moderate aerobic activity or 75 minutes of vigorous activity each week. Additionally, you should perform strength exercises that work all major muscle groups at least two days a week.
How do I calculate 150 minutes of exercise?
You can reach the 150-minute goal by performing 30 minutes of moderate activity five days a week. Moderate activity means your heart rate is raised and you are breathing faster, but you can still hold a conversation. Examples include brisk walking, cycling on flat ground, or mowing the lawn. If you prefer shorter, more intense bursts, 75 minutes of vigorous activity provides similar benefits. This includes running, swimming laps, or fast cycling. One minute of vigorous activity is roughly equal to two minutes of moderate activity.
Many people find it easier to track their movement in steps. While the often-quoted 10,000 steps a day is a useful target, research suggests that significant health benefits begin to plateau around 7,000 to 8,000 steps. The key is to avoid sedentary behaviour for long periods. If you work at a desk, standing up every 30 to 60 minutes can help mitigate the risks of sitting still, but it does not replace the requirement for dedicated cardio and strength work.
Why is strength training required twice a week?
Strength training helps maintain bone density, improves metabolic rate, and protects joints from injury as you age. While aerobic exercise focuses on the heart and lungs, resistance training ensures that your skeletal muscles remain functional. You do not need to lift heavy weights in a gym to meet this requirement. Bodyweight exercises, yoga, or heavy gardening like digging also count toward your two weekly sessions.
Focus on the "Big Five" movements to ensure you are covering all major muscle groups:
- Squats or lunges (lower body)
- Push-ups or chest presses (upper body pushing)
- Rows or pull-ups (upper body pulling)
- Planks or leg raises (core and stability)
- Deadlifts or glute bridges (posterior chain)
The recommendation is to perform these until your muscles feel tired enough that you would struggle to do another repetition with good form. This level of exertion is what triggers the body to maintain and repair muscle tissue. Over time, this helps prevent sarcopenia, which is the natural loss of muscle mass that begins after age 30 at a rate of roughly 3% to 5% per decade.
What counts as moderate vs vigorous activity?
It is important to distinguish between different levels of intensity so you can accurately track your progress toward the weekly goal. The following table provides a comparison of common activities based on their typical intensity for an average adult.
| Intensity Level | Type of Activity | Breathing and Heart Rate | Weekly Target |
|---|---|---|---|
| Low | Casual walking, light housework | Normal breathing; heart rate slightly elevated | Does not count towards the 150 minutes |
| Moderate | Brisk walking, flat cycling, water aerobics | Faster breathing; can still talk but not sing | 150 minutes per week |
| Vigorous | Running, uphill cycling, football, HIIT | Heavy breathing; difficult to say more than a few words | 75 minutes per week |

Is it possible to do too much exercise?
For the average person, the risk of doing "too much" exercise is low compared to the risks of inactivity. However, overtraining can lead to fatigue, persistent muscle soreness, and increased injury risk. Most health benefits are captured within the first 150 to 300 minutes of moderate activity per week. Pushing far beyond this—such as training for two hours every day at high intensity—requires careful attention to recovery, nutrition, and sleep.
If you are just starting, the safest approach is to build up gradually. If you currently do zero minutes of exercise, suddenly trying to hit 150 minutes may result in joint pain or burnout. Start with 10-minute walks and add five minutes to your total each week. This progressive overload is a core principle discussed in our wealth knowledge base of health information, as it prevents the "all-or-nothing" cycle that causes many people to quit.
How should I structure a weekly fitness plan?
A balanced plan distributes activity across the week to ensure the body has time to recover. You should avoid doing all 150 minutes in one day, as this increases the likelihood of injury. A sustainable weekly schedule might look like this:
- Monday: 30-minute brisk walk (Moderate)
- Tuesday: 20-minute bodyweight strength circuit (Strength)
- Wednesday: 30-minute brisk walk (Moderate)
- Thursday: Rest or light stretching (Low)
- Friday: 30-minute swim or cycle (Moderate)
- Saturday: 20-minute strength session or heavy gardening (Strength)
- Sunday: 30-minute brisk walk (Moderate)
This routine totals 150 minutes of moderate activity and two strength sessions. It fits into a standard working week and does not require expensive equipment. For more details on building long-term habits, visit our guide on personal development.
Does domestic work count as exercise?
Yes, but with a caveat. Cleaning the house or doing DIY only counts if it is intense enough to raise your heart rate and make you feel warm. Light dusting or tidying does not usually reach the "moderate" threshold. However, activities like heavy vacuuming, scrubbing a bathtub, or carrying groceries upstairs do contribute to your daily activity totals. The goal is to move your body against resistance or at a pace that requires more oxygen than resting.
If you are looking for ways to integrate more movement into your life without joining a gym, check our how-to guides for practical tips on active commuting and home workouts. Many people find that "non-exercise activity thermogenesis" (NEAT)—the energy expended for everything we do that is not sleeping, eating, or sports-like exercise—is the most effective way to maintain a healthy weight.
Frequently asked questions
Can I do all my exercise on the weekend?
Yes, research into "weekend warriors" suggests that squeezing 150 minutes into one or two days offers similar cardiovascular benefits to spreading it out. However, you may be more prone to injury if your body isn't conditioned for sudden, intense bouts of activity. It is generally safer and better for habit formation to move a little every day.
What if I have a physical disability or chronic condition?
The 150-minute guideline is a general target, but any movement is better than none. If a condition prevents you from reaching these numbers, you should aim to be as active as your abilities allow. You can find adapted exercises for different mobility levels in our health and wellness section, or consult a physiotherapist for a tailored plan.
Do I need to track my heart rate with a watch?
You do not need a wearable device to monitor your intensity. Use the "talk test" instead: if you can talk but not sing, you are at a moderate level. If you can only say a few words before gasping for air, you are at a vigorous level. While data can be motivating, your body’s internal cues are usually sufficient for meeting basic health guidelines.
Does walking count as strength training?
Walking is an excellent form of aerobic exercise, but it does not count as a strength session. Strength training requires you to work against a weight or resistance that tires the muscles. While walking strengthens the heart and improves leg endurance, it does not provide the specific resistance needed to maintain upper body muscle mass or significant bone density in the same way that lifting or resistance bands do.
