You can do fitness exercises at your age, but because your muscles, bones and organs are not well developed, I suggest you not do heavy weight-bearing exercises! So is nutrition. Because your organ development is not perfect, it is suggested that you adjust your nutrition through natural complementary food, and protein powder should be appropriate. A balanced diet is very important. According to your physical condition, if you want to supplement protein, I suggest you eat more red meat, especially beef. White meat is not suitable for beginners because it contains less calories.

As for the way of fitness, I suggest that you give priority to the whole body fitness (aerobic), supplemented by line-based projects (anaerobic). In anaerobic exercise, in order to lay a good foundation for your heavy-load exercise in the future, I suggest you use more basic movements, such as bench press, bending, squat, pull-ups (horizontal bar), arm flexion and extension (parallel bar), sit-ups and so on, instead of doing many fancy movements. The weight of each movement should ensure that you can complete 10- 12 (the specific weight should be mastered by yourself through actual combat training). Two movements at a time are enough for the muscles of one part, and each movement should be done in 3 groups, just * * * 6 groups!
