Great workout, coach.
I'm doing this soon but idk if I should use my 12lb dumbells for this or not… I'm in a hard to breathe environment as well so.. a HIIT with heavier dumbells than what Cozak is using… Fuck it it'll be so worth it if I go even halfway with heavier dumbells than usual for me 😀
this was the hardest workout I've ever done, love this guy!
great workout ! keep it going
You're the man!! Awesome workout!!!!

I totally stumbled onto coach and I am so glad I found these videos ….. keep up the great work coach you have inspired me to keep going no matter how long it takes
Thanks coach!! Great workout.
wow that was way harder than i expected great workout!!!
Life Changing, Thanks Coach!
Is this the same as the spartian 300 workout ?
So tough but brilliant!
Oldie but good one…
Whoa…killer! Gargling my heart LOL 😀
So nostalgic workout! It's kind of change after new workouts. Classic workouts are significantly faster-paced, but excercises are only 30 seconds long. New workouts are slower, but excercises are longer and movements are more complex. Common thing is that both workouts are great! 😀 One workout from the March plan. I just suddenly noticed that I got one day delay. I'm going to erease it soon though. Thanks for great workouts!
I will be doing this tomorrow as part of the 90-day warrior program. I am already freaking out today watching this !
bingo. perfect for my time limits today. gotta go now! Thanks!
What a brutal work out! Thanks coach – I think the soundtrack was just as brutal on my eardrums too! Made me laugh how bad that was 😉 Thanks as always!
Superb work out kozak. thank you so much for this awesome work out kozak.
Amazing workout. Thanks.
It is STILL a brutal workout! Thanks Coach 🙂
I don't know if anyone watches these videos anymore on here but I'm at week 13 of the Warrior 90 Program! What a blast it has been! Next I'm going to tackle the Hero Program!
