Judging from your situation, you should be fatter. . . Haha, give you some fitness methods and suggestions, hoping to help you. But the most important thing is to persist, otherwise nothing will happen.
First of all, you are short, muscular and have a small fat lung capacity, so you must not train blindly at first. The first step is to lose excess fat first and then talk about muscle training, otherwise it will be ugly and unrealistic.
As planned: 1. Jog for at least 30 minutes every day at an unlimited speed, but evenly. It's best to run as long as possible until there is no strength.
2. Stick to skipping rope for 20 minutes every day and jump at your fastest speed.
Function: activate muscles in all parts of the body, consume a lot of fat and improve vital capacity. Maybe your legs will be tired at first, and you may even feel sore all over. In this case, skipping rope can be interspersed, but long-distance running must be adhered to every day!
Note: the above should be held for at least 2-4 weeks, so that the physical function can begin to rise slowly, and then continue to exercise at other intensities.
For the plan: 3. Seeing that you are eager to lose belly fat, I will tell you the way, only sit-ups. But there are many forms, and the restored parts are different. The first type: lie flat on the mat (the bed is ok, but not too soft), bend your legs 90 degrees, or straighten (recommended), put your head in your hands, and lift your upper body by waist strength. Location: mainly exercise the upper abdominal muscles (reducing fat, the same reason). The second type: lie flat on the mat, put your hands flat on your sides, put your legs together, and lift your legs at 90 degrees by waist strength (get up and fall quickly, but don't stick your legs on the ground (bed surface) when you fall, otherwise all previous efforts will be in vain. Location: Mainly practice small (lower) abdomen. The third type: like the first two combinations, the legs and upper body get up at the same time, and the hands touch the toes as much as possible, which is also to get up and fall quickly, and the legs do not touch the ground when falling. Location: comprehensive abdominal exercises, the most tired one.
Do three groups of the above three sit-ups, each group 10-20. Because everyone's physique is different, usually the effect will be more obvious if they persist for 3-5 months.
If you still don't understand, you can ask me. It's all up to you. . . Tired. . . Hope to adopt
