  1. Your physique looks awesome man! That vacuum was crazyyy! Definitely gonna start implementing this in my morning routine

  2. I didn't know you had a.channel. I saw this and you intrigued me to try. I did it. That don't you turn this into a 30 course.I could only hold it for 10 seconds. Many make it a course! I really want my belly to be flat. I'm gonna try THANKS

  3. For the viewers. When you exhale pull in your belly button as far back as you can as if you were trying to touch your back with the front. If you did it right, the next day you will feel some muscle soreness in that area. Great video Juan!
