How Much Exercise Do You Really Need? A Doctor's Guide to Weekly Fitness

There is a lot of conflicting advice about how much exercise people need. Some believe you need to work out every day, while others think a few workouts a week are enough.

The truth is that you do not need to spend hours in a gym every day to improve your health.

What matters is getting enough regular physical activity and building a routine that you can maintain.

How Much Exercise Should You Get?

For most adults, current physical activity guidelines recommend:

• •At least 150 minutes of moderate-intensity aerobic activity each week, or
• •At least 75 minutes of vigorous-intensity aerobic activity each week, or
• •An equivalent combination of moderate and vigorous activity

Adults should also perform muscle-strengthening activities on at least two days each week.

You Don't Have to Exercise All at Once

Your weekly activity can be divided into smaller sessions. For example:

The exact schedule is not important. Consistency is.

If you are currently inactive, even smaller amounts of activity are a good starting point.

What If You Currently Do Very Little Exercise?

Do not suddenly begin an intense exercise programme. Start with what you can comfortably manage.

For example, you could begin with a 10 to 15-minute walk and gradually increase the duration as your fitness improves.

The goal is to build a habit rather than exhaust yourself during the first few sessions.

Is Walking Enough?

Walking is an excellent form of aerobic activity and is a good starting point for people who are inactive.

However, a complete fitness routine should ideally include some form of strength training as well.

Strength exercises help maintain muscle strength and physical function, while aerobic activity supports cardiovascular fitness.

Don't Ignore Movement During the Day

A workout does not mean you should remain inactive for the rest of the day. If your work involves sitting for long periods, look for opportunities to move. You can:

• •Take short walking breaks
• •Stand while taking some phone calls
• •Use stairs when appropriate
• •Walk during breaks
• •Move around between tasks
• •Take a short walk after work

Small amounts of movement throughout the day can help you become more active overall.

What About Older Adults?

Adults aged 65 and above should include aerobic activity and muscle-strengthening exercises according to their abilities. Balance activities are also important for many older adults.

People with mobility limitations or medical conditions may require an individually adapted exercise programme.

Is More Exercise Always Better?

Not necessarily. Exercise should be appropriate for your fitness level, health, age and recovery capacity.

Increasing exercise without allowing adequate recovery can lead to excessive fatigue and may increase the risk of injury.

The goal is not to exercise as much as possible. The goal is to exercise enough to improve your health and fitness sustainably.

The Bottom Line

You do not need a perfect exercise routine. Aim for regular aerobic activity, strength training at least twice a week and less prolonged sitting.

Start at your current fitness level and gradually build from there.
