How Many Times a Week Should You Actually Exercise?

One of the most common questions people have when they start thinking seriously about their fitness is how often they actually need to exercise.

Is twice a week enough? Should you be aiming for three or four sessions? And are the people exercising every single day getting much better results than everyone else?

As with most things in fitness, there isn’t one perfect number. How often you should exercise depends on what you’re trying to achieve, what type of exercise you’re doing and, perhaps most importantly, what you can realistically maintain.

For most people who simply want to be stronger, fitter and healthier, you probably don’t need to exercise as often as you think.

Two or Three Good Sessions Can Go a Long Way

When it comes to strength training, two or three well-structured sessions each week can be enough to make a meaningful difference.

The key is what happens during those sessions. Your muscles need to be challenged sufficiently to give them a reason to adapt. Over time, that might mean gradually lifting a little more weight, completing more repetitions or becoming more capable at a particular movement.

You don’t need to train every day for that process to happen. In fact, the time between sessions is part of the process too. Training provides the stimulus, while recovery gives your body the opportunity to adapt to it.

This is one of the reasons we’re much more interested in what someone can consistently do for months and years than what they can manage during one particularly enthusiastic week.

What About Cardio?

Strength training is only one part of the picture. Looking after your cardiovascular fitness matters too, but that doesn’t necessarily mean adding several long, exhausting workouts to your week.

Walking more, cycling, swimming, running or doing a class that gets your heart rate up can all contribute. Even everyday activities such as walking the dog, gardening or taking a brisk walk at lunchtime help us spend more time moving and less time sitting.

The NHS recommends that adults aim for around 150 minutes of moderate-intensity activity each week, or 75 minutes of vigorous activity, alongside strengthening activities on at least two days per week.

That might sound like a lot when written down, but those minutes don't have to happen in the gym and they don't have to be completed all at once. Movement accumulated across your normal week counts too.

More Exercise Isn't Always Better

It's easy to assume that if exercising three times a week is good, exercising six times must be twice as good. Unfortunately, our bodies don't quite work like that.

There comes a point where adding more training doesn't necessarily produce better results, particularly if you aren't recovering properly between sessions. Sleep, nutrition, stress and the demands of everyday life all affect how much exercise we can comfortably recover from.

This is particularly important if you're returning to exercise after a long break. Going from doing very little to training five days a week might feel incredibly productive initially, but if you're exhausted and aching after a fortnight, it probably isn't a routine you'll maintain for very long.

Starting with two sessions and consistently completing them is far more valuable than planning five and regularly managing two.

Don't Forget the Rest of the Week

It's also worth separating exercise from movement.

You might only have two or three structured workouts in your diary, but that doesn't mean the other four or five days should involve doing nothing. Walking, taking the stairs, playing with the kids or grandchildren, doing jobs around the house and generally spending less time sitting all contribute to an active lifestyle.

Your workouts are important, but they're only a few hours out of a 168-hour week. What happens outside them matters too.

This is why someone who strength trains twice a week, walks regularly and stays generally active can have a very effective routine without feeling as though their entire life revolves around exercise.

So, What's the Right Number?

If you're currently doing very little, even one or two sessions each week is a fantastic place to start. If you're already exercising regularly and want to improve your fitness further, you might benefit from doing more.

There isn't a magic number that everyone needs to hit.

For most people, a combination of two or three strength-based sessions each week, some cardiovascular exercise and plenty of everyday movement is a great foundation for long-term health and fitness.

The most important question isn't really, "How many times should I exercise?"

It's whether the routine you've chosen is one you can keep doing.

Because three workouts this week might feel impressive. But two workouts a week, consistently completed for the next year, will almost certainly take you further.
