The phrase “150 minutes a week” can sound impossible if you are currently doing almost no structured activity. It helps to understand that the target is a destination, not a minimum entry requirement.

WHO recommends at least 150 minutes of moderate-intensity aerobic activity per week for adults, with muscle-strengthening work as well. In 2022, about 31% of adults worldwide were not meeting recommended activity levels.

Start with a dose you can recover from

If a 30-minute walk leaves you exhausted for two days, start smaller. Ten minutes may be enough. If ten is too much, start with five. The first goal is to create a pattern you can repeat.

Use frequency before intensity

Three short walks across the week are often a better foundation than one heroic session followed by several inactive days. Once the routine feels normal, increase duration or pace gradually.

Add strength early

You do not need a gym to begin strengthening. Sit-to-stands, wall or counter push-ups, step-ups, calf raises and loaded carries can all be scaled. The correct exercises depend on your health, mobility and symptoms.

Use the talk test

Moderate-intensity activity usually makes you breathe faster while still allowing you to speak in short sentences. Heart-rate targets can be useful for some people, but perceived effort is a practical starting tool for many.

Make the environment help you

Keep walking shoes visible, choose a regular time, pair activity with something you already do, and remove unnecessary setup. The easier the first two minutes are, the more likely the habit is to happen.

If you have significant heart, lung, neurological or other medical conditions, or symptoms such as chest pain, unexplained fainting or severe shortness of breath, seek appropriate medical advice before pushing intensity.

Bottom line: do not wait until you can meet the full recommendation before you begin. Any increase from your current baseline can be a meaningful first step.

Build the first month around consistency

A simple first month might look like this: three short walks per week and two ten-minute strength sessions. If that is already more than your current level, start smaller. The next week, add only one thing, such as five minutes to one walk or one extra set of an exercise.

This is intentionally modest. The aim is to finish the month with a routine that feels normal enough to continue, not to complete a dramatic challenge and then stop.

Use everyday movement as part of the total

Structured exercise matters, but your day also includes walking to transport, taking stairs, shopping, cleaning, playing with children and other movement. If you are starting from a very low baseline, adding a short walk after dinner or walking part of a usual journey can be meaningful.

Choose progress markers that are easy to notice: walking the same route with less breathlessness, climbing stairs with fewer pauses, completing more sit-to-stands, or feeling less intimidated by activity. Those wins make the guideline numbers feel connected to real life.
