Domino's really thin so I thought I could challenge her to a belly punching contest...but she was really confident because she knows i didnt train for over 2 months because of my surgery, she knows Im out of shape... so we decided to do 10 punches standing, 10 punches with our backs against the ball (I cheated a little bit) and 10 punches on the ground, laying down. we compared our stomachs to see which one was more red.... one thing is for sure,we didnt count until 10 all the time...I dont know hy we wouldnt keep the count! but its always 9-10 or 11!!
