It helps, but it’s definitely not the only way.  Even walking every day can help you lose weight.  And don’t forget about those resistance/strength exercises. A pound of muscle uses 75 to 150 cals a day whether you consciously use it or not—so building muscle is key to losing weight from exercise.  The bottom line is, if you’re moving and active, you are well on your way to losing weight.  If yoga, wall sits, or a walk around the block is your preferred activities, keep it up and try to up the intensity every once in a while.

No, you do not. Weight is lost whenever the body consistently brings in fewer calories than it burns. The simple formula needed to lose a pound of fat is to create a calorie deficit of 3,500 calories. This means that you will need to consumer 3,500 calories less than you burn. To make that goal more manageable, think that you need 500 fewer calories eaten than burned per day. How that deficit is achieved is up to you. You can simply eat 500 calories less a day, but you may get hungry. Or burn 500 extra calories a day. Or you can eat 200 less and burn 300 more. It is generally recommended that you reduce your calories consumed to a comfortable level and that you increase your total daily activity. That activity can come from cardio, weight training, yard work, walking the dog, or simply finding little ways to burn more calories all day long. Simple things like parking farther away, taking the stairs, walking to a co-workers office rather than emailing or using the phone, and standing and pacing in your office rather than sitting at the desk can add up to several hundred extra calories burned over the course of a day.

No, you do not have to do cardio to lose weight; however, research indicates that exercise – resistance training, cardio, or a combination of each – can greatly enhance your weight loss success. Ultimately, to lose weight the body must be put into a position where it is required to use stored energy (fat) as fuel. To do this, a deficit must be created between the amount of calories consumed from food and the amount of calories burned by the body to power itself and physical activity.

While this deficit can be created by reducing calorie intake from food, research indicates that a combination of a reduced-calorie diet and exercise is superior to dieting only. For example, a review published in the International Journal of Obesity found that compared to dieting alone, the combination of exercise and dieting resulted in both 20% more initial weight lost and greater weight-loss sustained after 1 year.

Therefore, based on the research it is extremely important to consistently incorporate some form of physical activity into your weight loss plan. If the thought of cardio exercise doesn’t appeal to you, then give total body resistance training exercises like the Side Step-up, Balance to Overhead Press with 2-Arms (seen below) a try. Exercises like this one are time-efficient, work multiple muscle groups at once, and help you maintain your muscle tissue while you lose weight – helping you stay defined and toned as a result.
