Doing sit-ups is simple and effective to practice abdominal muscles. You can also lie flat on the bed and touch your toes with both hands (lift your body). Do it slowly. If it is fast, there will be inertia, which will affect the effect. Be sure to do it to the end and do it in place.

Each group does the limit. Remember not to do it every day, but every other day. Every time you do anaerobic exercise, you should destroy your muscle tissue as much as possible, and then use enough time and nutrition to repair the damaged muscle tissue and let it grow. To put it bluntly, muscles grow out at rest after anaerobic exercise.

Must be combined with aerobic exercise,

All aerobic exercises are good ways to lose fat, such as running, skipping and swimming. In addition, when summer comes, buy a disposable raincoat, run at home (don't turn on the air conditioner), swing your arms quickly and sweat more, which will not only reduce fat, but also detoxify. Replenish water in time. The above exercises should last for more than half an hour at a time, otherwise they will be invalid. Eat less food with high oil and heat. If you just do sit-ups, the fat layer will not decrease, the muscle layer will thicken and the waist will be thicker.

Only by scientific fitness can we have perfect muscles. (Original, don't copy)
