Abdominal muscles I got at this stage is not, but could already feel a certain tightness. Since I did not want to overdo it, I stayed one week every day at level 25th
After a week was increased to 32 and again one week later to 40. I have to say that firmness has increased and my stomach feels much stronger than before. My goal is not the washboard abs, but I just want to have a pleasant round-gut feeling.
I regret not buying. It is really first class !!!!!!
