The daily fitness plan is all the equipment in my student party diagram. I need to develop abdominal muscles and muscles.
It is not suitable for minors to exercise a lot of muscles, but there is no other way to develop abdominal muscles. Only running, there is no doubt about it. Even if you do 10000 sit-ups every day, you might as well run for 40 minutes. So what you need is aerobic exercise+200 sit-ups every day to ensure that abdominal muscles appear for one month, and the running heart rate =(220- age) *0.7.
