How often should you work out for weight loss? Knowing how often you should strength train and do cardiovascular exercise (有氧运动) to lose weight depends on how quickly you want to see results. The general recommendation is to lose no more than 1 to 2 pounds per week.

In the simplest of terms, you’ll need to burn more calories than you take in to lose weight. Dieting has proven to be an effective method of losing weight, but in order to maintain weight loss, you need to exercise. How much weight you lose depends on the amount of exercise you’re willing to commit to and how closely you stick to your diet. If you really want to see results reflected on the scale and continue to make progress over time, you need to commit to working out at least four to five days per week.

But remember, you’ll build up to this. To start, you might only want to do two or three days per week and slowly work your way up to five days.

To get the most out of your weight loss workouts, make sure you’re following these guidelines:

▲Vary the intensity (强度) of your workouts. Include both high-intensity interval training and moderate-intensity exercises.

▲Perform different methods of cardiovascular exercise in a week, like running on the treadmill, biking, and swimming.

▲Use circuit training when lifting weights to keep your calorie burn high. Circuit training involves doing a series of exercises, one after the other, with no rest between each exercise. At the end of the series of exercises, you typically rest for a set period (30 to 60 seconds) and repeat the circuit two or three more times.

▲Take at least two days of rest each week.
