The general principle is to do more aerobic exercise, choose exercises with less load, more times and fewer groups for strength exercises, and have a balanced diet and nutrition, so there is no need to supplement protein food.

In terms of aerobic endurance, if you want to build a thin figure, you should use long-term and low-intensity aerobic jogging or brisk walking. The average time can reach 40~60 minutes, and exercise 3~5 times a week. This can reduce body fat for a long time and make the body more coordinated and flexible.

In strength exercises, such as using dumbbells to exercise muscles, dumbbells are compared by fitness enthusiasts to hammers and chisels that shape muscles. In order to reduce fat, it is suggested that each group should practice several times, such as 15-25 times or more in each group. In order to avoid boring strength exercises, you can choose a suitable music rhythm.

Because the two dumbbells are completely independent, in order to keep the balance and stability in practice, the body will use all possible muscles, including all tiny synergic muscles and antagonistic muscles, thus improving the coordination and control of people and making the body more symmetrical and straight. In terms of diet, balanced diet and reasonable nutrition are the general principles.

There is no need to deliberately ask for more food in protein. At the same time, we should pay attention to the intake of desaturated fatty acids, and don't limit sugar excessively during exercise. A slim and symmetrical figure needs a healthy life as the foundation, and scientific exercise can ensure a slim figure.
