Flexing your muscles does burn some calories, and there's actually a name for this type of exercise: isometrics. However, isometrics alone aren't enough to cause significant weight loss. To shed fat, create a multi-pronged plan that includes a reduced-calorie diet, regular aerobic activity and strength-training exercises such as isometrics, weight training or calisthenics
Isometric Flexing
When you hold a body part still while flexing the muscle, you are performing an isometric exercise. For example, you can perform an isometric chest press by clasping your hands together in front of you and pushing your palms together to flex your chest muscles. In contrast, a barbell chest press is an isotonic exercise because you lengthen and shorten muscles by bending your joints as you flex.
Calories
The number of calories you burn while flexing depends on the muscles used and the duration of the exercise; however, flexing is unlikely to burn a large number of calories. A pound of fat is approximately 3,500 calories -- so all other things equal, it would take nearly two dozen sessions to lose a single pound. Every little bit can help though.
A few year back I would end my Wednesday and Friday routine with 1/2 of posing. This served as a great measuring point for identifying areas to concentrate on improving on. I would be completely exerted. I never noticed a weight lost but seen some improvement in areas I would have never known need additional attention..
