Sit-ups, sit-ups and leg lifts, sit-ups at both ends, three combinations. 5 groups for each extreme exercise. The above is the initial training, and now I don't even bother to watch it. The following is the advanced training and the ultimate basic training. It is through the following training that my abdominal muscles gain real strength. If your suspended vertical leg lift can reach 10 (the best standard, no inertia) and the L-shaped leg support (straight (pointed) angle support) can reach 15 seconds (preferably on the flat ground), then you can carry out advanced training. The limit of each group of vertical leg lifts and L-shaped leg stays is at least 10 group. Why should I say at least at the end? Quite simply, that's because the 10 group is the least. You can do more groups if you have the strength. Abdominal muscles are tolerance muscles, and the more you practice, the better. ) practice every other day. If the abdominal muscles don't hurt, practice every other day. In fact, as long as you don't slack off and practice as I say, you will definitely get in place, and it will hurt when you get in place. Pain requires rest, and rest is naturally the next day. If it is tearing pain, it is not normal. This is a strain. I think you can tell what kind of pain it is.
