I tried this workout for the first time today. My upper body strength is far from being good, so I really struggled with the L-sit and returning to an upright position after doing a walkout. It was rather discouraging, but I wanted to commit to making it to the end of the workout despite struggling with some of the moves and taking breaks.

However, I am proud that I didn't stop. I would've never been able to do more than ten minutes of this workout a month ago. I'll definitely keep coming back to this workout because I want to get stronger.

Did this one outside for extra strain. Very frustrating being in between multiple levels of modification. Could you please send link for lengthy periods cardio endurance? I have got to conquer the extra challenge of medications slowing down weight loss. Also just joined Patron! Thanks for all you guys do!

Great workouts. I love the variety of movements. I've been doing power lifting for awhile but wanted to get my cardio and athletic side back. This really helps. You have my support.

week 2 of the calendar! I have made it through the workout and i am proud! I never knew my legs would be able to keep up and do as many things as they did but I pushed through. Only regret I have is not joining the HASFitTribe soon enough!


WOOT! Instead of showing intensity by number of "flames," it should show Coach Kozak with perfect hair (easiest) to completely mussed up hair (hardest). This is the first workout i've seen where Coach K not only defeats pain, but also defeats his hair gel!

I would like to tell you guys that I am eternally grateful for your videos. I had to move temporarily to a place with no gyms and working out is my addiction. Your training videos get me through the tough times. Thank you so much.
