Contrast therapy (cold to hot or vice versa) is actually really good for improving your circulation, so it is good for you

The fact you’re running a sub 7min mile while still holding a conversational pace is mind blowing to me. Guess I’m going to go run

Nah bro, Isaiah’s dedication and determination to become such a great YouTuber is just super respectable. Keep it up bro ❤

[AverageTeen]

Cold to hot water is a good idea, this is called contrast therapy! We use this regularly

[richardhernandez]

Finally some good content to watch while I eat my breakfast. Never disappoints 👌

[danielfarison]

Saw this on Strava, you destroyed it💪

[joshuawilson]

Bro.. this was so inspirational seriously dig your heels in to this goal, when that couch was so comfortable and you did it. You fought. I got chills I threw a chaw in and I'm about to go get a nasty ass run in. 💪💪💪

[boxytheboy]

Now thats determination. Isaiah is insane bro. Keep up the good work

[JustGrantHorn]

One day we’re gonna collab, I’m calling it

[joshuarusselldagastino]

I think this is a cool video. I'm just confused, I don't think David Goggins who did like 60 ultras is fearful of this workout?
