Weights or cardio? Why your body benefits from both

What counts as cardio?

Aerobic—or cardio—activity raises your heart rate and breathing for a period of time. Examples include brisk walking, cycling, swimming, dancing, rowing, wheeling and many sports.

It can improve cardiovascular fitness, stamina, mood and the ability to manage longer periods of activity. Moderate intensity usually means you feel warmer and can talk but would find singing difficult.

What counts as weights or resistance training?

You do not need to lift heavy dumbbells. Resistance can come from your body weight, bands, machines, household objects or moving against gravity.

• rising from a chair or doing a supported squat
• wall or worktop press-ups
• resistance-band pulling or pushing
• carrying shopping or doing heavier gardening
• lifting weights or using gym machines
• adapted seated resistance exercises

Resistance work supports muscle strength, physical function and the ability to manage everyday tasks.

Which is better for weight loss?

Cardio often uses more energy during the activity, but exercise alone usually produces only modest weight loss. Its wider health and fitness benefits still matter greatly.

Resistance training may not make the scales fall faster because muscle is being protected or built. During dietary weight loss, research suggests it can reduce the loss of fat-free mass, improve strength and support loss of body fat. This is particularly relevant when appetite and weight fall quickly, including for some people using weight-management medication.

A changing body composition can be progress even when total weight changes more slowly.

Do strength sessions count towards the cardio target?

Usually not. UK guidance asks adults to work gradually towards 150 minutes of moderate aerobic activity each week—or 75 minutes of vigorous activity—and to do muscle-strengthening activity on at least two days.

Some activities train both at once, such as circuits, energetic dancing, stair climbing or certain sports. You do not need to keep the categories perfect; the aim is to develop fitness and strength across the week.

A simple way to combine them

If you are beginning, try:

• Cardio: a manageable walk, cycle, swim or other rhythmic activity on two or three days.
• Strength: a short routine using two or three movements on two non-consecutive days.
• Recovery: lighter movement and rest appropriate to how your body responds.

These can be very short at first. Build only one thing at a time—duration, frequency or difficulty—and choose activities that fit your health and ability.

If you only enjoy one

Doing the activity you will actually repeat is more valuable than an ideal programme you avoid. Keep the form of movement you enjoy and add a small amount of what is missing. A walker might add chair rises and wall press-ups; somebody who enjoys weights might add short brisk walks or cycling.
