This is the FULL LENGTH CHALLENGE! We were exchanging Punches to the belly for over 10 min. She was going way harder than me. She is so tough, her abs are so hard...you can see it in the video, abs of steel. I was very impressed! Ariel X is one of the toughest girl I met. She can take a lot of pain. In that video, even if im not in shape like her, youll see I can take a lot of pain too. She is punching way harder than me, and I still take the punches. If you like medium to very hard punches to the stomach, youll love that one!
