Tighten & Flatten Your Stomach in 1 Move No Sit-Ups or Gym

Tighten & Flatten Your Stomach in 1 Move No Sit-Ups or Gym Tighten & Flatten Your Stomach in 1 Move (No Sit-Ups or Gym) Dr. Mandell This exercise that I will present is the best exercise you can do for your abdominal region. The transverse abdominis muscle is what holds and supports the lower back and pelvic structures. These muscles must be strong to help support the surrounding organs and other core muscles. These muscles support breathing by helping to pull the abdomen inward, and in that way force air out of the lungs to make room for a new breath of fresh air. These muscles also raise the intra-abdominal pressure which is necessary for functions like urination, defection (having a bowel movement), vomiting, and vaginal childbirth.
