  1. This my favorite morning workout gets me pumped for my day

  2. Challenging but I pushed until the end oh man!..

  3. You can get best workout for 10 dollars, just look on Unflexal website.

  4. I cant find many workouts I can do because of all the weight on my wrists and lower arms, having to do positions where you are supporting yourself with your arms. This kills my wrists and lower arms so that I cannot even finish the workout or do much of it at all. 🙁

  5. i can't even walk after this I feel old and i'm 19

  6. Thank you very much. This is an awesome workout!!!

  7. You can check Unflexal to learn more about training your body.

  8. I loved your classes! thank you very much!!!

  9. Great workout, tough, but sweet 🙂

  10. aah! that was killing! good one though…

  11. Ok, so i used to do this like 2 or 3 years ago, i lost 7 pounds in a month, but i also wasn't dieting. This time i'm doing this and a inner thigh workout (and eating healthy). I will do each exercise every day for 2 months. I will share results in 2 months! 😀

  12. Excellent Video clip! Sorry for chiming in, I would appreciate your thoughts. Have you tried – Chireetler Exclusive Workouts Rule (do a google search)? It is a good one of a kind product for learning how to burn fat fast using a unique super hero method minus the hard work. Ive heard some incredible things about it and my cousin finally got amazing results with it.

    and this workout kicked my butt!!! Awesome!!

  16. the workout video wherein its prohibited to rest.

    i like it tho

  17. Great workout, but it feels like a torture at some point, I like to enjoy workouts not to suffer, I guess I need to get to this level in order to be able to do it non stopping and
    not need to rest at least 3 times during the workout.

  18. I made it to the 1:06 I had to stop???umm a kid so it's different

  19. Excellent workout.. Highly effective.

  20. When she says keep your core tight does she mean suck in?????

  22. You have the sexiest ass Ive ever seen 🙂

  23. I totally loved it!!! It made me so happy to find such a great workout!!

    Thank youuuuuu xxxxoxoxoxoxoxoxooxoxox

  24. Ofcourse you'll need to do it a couple of dozen times to have any effect, so more like the 6 hour workout. Not so appealing now eh?

  25. Hi Anna I am 245lbs and 5 foot 11 use to be 6 foot 2 and 215. I also had a baby 1 year ago and really need to loose my flabby stomach! Any suggestions?
