Do you eat in moderation? Three meals a day is enough, especially at night. No dinner or dinner. It's easy to exercise muscles. Take a dumbbell on your arm and biceps brachii and do several groups of flexion and extension exercises every day. Wrist and forearm can be made into a self-made device, which is very effective-use a strong wooden stick, nail a few nails in the middle, then fix a rope at the nails, tie a heavy object, such as a brick, stir it up with both hands, then slowly put it down, and so on.
For abdominal muscles, the upper eight abdominal muscles can sit up, and the lower eight-after lying flat, the legs are together, slowly on the stage, and then slowly put down. Leg muscles can be accelerated by running, long jumping or high leg lifting.
