How Often Should You Do Cardio?

"How often should I do cardio?" is one of the most common questions we hear — and the honest answer is that it depends on what you are training for. There is no universal number that suits everyone. The good news is that finding your own answer is simple once you know what you are aiming at, how cardio fits with the rest of your week, and how to read the signals your body sends. More is not automatically better; the right amount is the one that supports your goals and still leaves you feeling good.

Start with a sensible baseline

For general health, most guidelines point toward a modest weekly amount of moderate activity — think a few sessions of brisk walking, cycling or anything that gently raises your heart rate, spread across the week. That is a comfortable baseline for almost anyone, and you can build it from short sessions rather than one long slog. If you are currently doing very little, even two or three easy sessions a week is a meaningful start. From that base, you adjust up or down depending on your goal.

Let your goal set the amount

Cardio frequency is not one-size-fits-all — it flexes with what you want from it:

• General health — a few moderate sessions a week is plenty to feel the benefits.
• Building endurance — a bit more frequency and gradually longer sessions, added slowly over time.
• Supporting fat loss — cardio you enjoy, alongside strength and daily movement, rather than piling on endless sessions.
• Alongside heavy lifting — often less structured cardio, so it complements rather than competes with your strength work.

Mixing intensities helps, too. A couple of easier, longer sessions and one shorter, brisker effort covers more bases than doing the same hard workout every time.

Fit it around strength and life

Cardio does not exist in a vacuum — it shares your week with strength training, work, sleep and everything else. If you lift a few times a week, you may only need a little dedicated cardio on top, especially if you also walk plenty day to day. Try to leave some space between hard cardio and hard leg sessions so neither suffers. And remember that recovery is part of the plan: rest days are when your body absorbs the work, not time wasted.

Above all, listen to your body. Persistent fatigue, disrupted sleep or dreading every session are signs to ease off, not push harder. Cardio should leave you feeling better over time, not steadily worn down.

Find the amount you can keep up

In the end, the best cardio frequency is the one you can sustain comfortably while still enjoying your training and your life. Start with a modest baseline, adjust it to your goal, keep it in balance with your strength work, and pay attention to how you feel. A steady, moderate habit you keep for years will always do more for you than an ambitious schedule you burn out on in a month. Pick an amount that fits, give it time, and let consistency — not intensity — carry the results.
