Simply put, sit-ups are slow to take effect! I suggest you make a compound contact: 1 The end abdomen means lying flat with your hands on your lower abdomen.
Straighten your toes.
Lift the leg at an angle of 30 degrees with the horizontal plane and hold it for 5 minutes.
Don't stop when you go back in time.
Hands and feet are separate.
That is, hip concentration.
Hands and feet lift each other.
Step by step, every time.
Down to earth! Add 50 times every 5 minutes as a group.
It is not advisable to do two more groups every day.
Moderate is good.
Add 3-5 tablets every day.
Guarantee the effect of 15 days. Hmm. How interesting
