The claim

“Cardio is the best exercise for weight loss.”

It depends
Evidence confidence Moderate

Moderate confidence because aerobic exercise tends to produce more scale-weight loss than resistance training alone, while combined training can be better for fat loss and preserving lean mass. The best plan depends on the outcome and adherence.

The facts

Aerobic exercise tends to produce more scale-weight loss than resistance training alone, while combined training can be better for fat loss and preserving lean mass. The best plan depends on the outcome, personal preference and adherence.

The bigger picture

No single workout style determines your health. Total activity, strength, fitness, recovery and consistency all matter.

Can cardio support fitness or weight goals?

Cardio can improve fitness and help with calorie use. Strength training helps keep muscle, so using both can work well.

What this means for you

You do not need to choose between cardio and lifting. For most people, some of both is a strong, realistic plan.

Your next step

Keep or add two strength sessions each week and use walking, cardio or sports you actually enjoy for the rest.
