Dude basically broke all the cardinal rules of getting healthy. Over-did the exercise, under-ate, didn't rest, set unrealistic goals, obsessed over weight, took on an unsustainable lifestyle, picked sports he didn't enjoy... and still did it. That sort of stubornness is impressive.

The fact u survived a 12 mile run on the first day is amazing.

This is honestly mind blowingly impressive. To go from completely sedentary to 12+ miles a day, an ultra, and ironman ready to 100 days is wild

Bro I’m a Marine and I’ve seen people push themselves to the limit time and time again however you took it to another level. You should be so proud of yourself congratulations.

"I don't know why he was telling me his workout routine, I already have mine" had me cracking tf up

Most people will never understand that each day in this video was like 3-5 seconds for us… But this man lived in an isolated, self inflicted pain chamber for 2400 hours without breaking

I think the plateau was you gaining muscle 😂

Not going to lie, this made me cry. Doing hard things and not giving up as someone who isn’t a pro, is inspirational always.

Came here to say that Goggins just shared your journey on his Instagram and gave you a great shout out, mad respect my dude!

I’m so proud of you :) even though you still worry me every day

The fact this never cut to a sponsorship made it so much better

Reminder for people comparing themselves, this guy could run 12 miles on day 1 and an ultra marathon in the first month

I'm 49.  64 days ago I watched this video and started doing daily distance runs and resistance training.  Today I ran my fastest 5k ever, and I've lost 26 pounds.  Just wanted to say thanks for this!

This felt like old youtube when it was at its prime, keep being you man

Incredible.
It's like he did 0 zero research, like he knows nothing. He does everything wrong, yet he just pushes through.
No complaining, just determination. Actually incredible effort.

for anyone trying this. Start out by just walking those 12 miles for 30 days. This gets your metabolism going, you already will loose a ton of weight just from doing this and eating healthy. dropping a bunch of weight will also help you to run better, because if you go from 0 to 100, you may hurt yourself more than it is worth. you do not have to start out with all of this stuff. do walking for 30 days, then ramp up by adding a workout routine after that and the next 30 days after that you go and start running. much better on your body, because running is alot of stress on your joints, and doing this overweight is no fun, as you can see in this video :D

As a triathlete (and doctor) myself, that was completely insane.  I can't believe you didn't get rhabdomyolysis from muscle breakdown from working out so much.  Your will is massive.  Now you've done your challenge, the next challenge is to create a sustainable lifestyle.  Your body needs rest.  Rest will build more strength and your body will dangerously breakdown without it.  From couch to Ironman in 100 days is bonkers, well done.

Doc: "I work out 3 times a week"

Asian Goggins: "cool, didn't ask"

Man said I’m a fat lazy guy and that sucks, and then 20 days later was running an Ultra Marathon.

A prime example of the indomitable human spirit, you sir, are excellent

this made me really anxious to watch. Your goal clearly wasn't to become healthy, but to become an idealized tough-nut. I'm just glad you're finally realizing that the issues come from inside and that your friends and family care about your long term health! You did something incredible, and I hope you can gain strength from how proud that must have made you. <3 best wishes!
