These sessions of core muscles were recommended by my wife. Earlier I was training with weights in a gym. After first session I was surprised. Training was different than I was thinking. I felt muscles, which I didn’t feel before, worked and hurt, even session’s load wasn’t challenging.
I have lost 12 kg without limiting my food ration. After deep core muscles trainings I feel more powerful than I was before. I don’t experience pain in my spine anymore, my joint became stronger and whole look is different now. In my opinion, I won’t find more effective and interesting sessions.
