This is a pretty big fitness misconception: “Doing cardio is the only way to lose weight!”
Cardio is in fact good for the heart and increases endurance, but alone is not the best way to burn fat.
Weight loss is most effectively achieved through a combination of both cardio (such as running, biking, or swimming) and strength training.
While the cardio will get your heart rate up, strength training adds muscle mass to your body, and increased muscle mass means an increased metabolism.
In other words, adding even a few pounds of muscle will increase the number of calories your body burns each and every day.
If you focus only on cardio it might become harder for you to lose weight. In particular, excess cardio could significantly decrease your muscle mass, as a consequence slowing your metabolism and that will result in an overall weight gain.
So, if you have a limited amount of time to workout everyday (let’s say 1 hour) you should really seek to mix cardio with strength training: that’s the best recipe possible. And if you’re not sure what to do, ask your the personal trainer at the gym he/she will have plenty of tips to help you out.
