1, sit-ups
Speaking of training abdominal muscles, I believe everyone is familiar with sit-ups, which is one of the most classic methods of training abdominal muscles. Then we office workers can often exercise sit-ups in some spare time, and it won't take long to finish them as long as we concentrate. For example, as long as you insist on doing 50~ 100 sit-ups every day, you will see the effect in about three months. Such sit-ups are common.
2, supine abdomen
In addition to sit-ups, sit-ups are also a good way to strengthen abdominal muscles. This method is relatively simple. First, we can relax and lie flat on a flat surface, then put our legs together and slowly raise them to a 45-degree angle to stop. We can keep this action for 5~ 10 minutes every day. This action is to consolidate the training effect of sit-ups, so I suggest doing it directly after sit-ups practice.
3, supine high leg lifts
Lying on your back and lifting your legs is mainly to consolidate some lines around our abdominal muscles. Its practice is to lie flat on a flat place and stand on the high platform alternately with both legs until it stops at 90 degrees, so that it can be done alternately for about 60~ 100 times. This kind of training will have obvious effect if it lasts for about three to six months every day.
