St1ff : did not watch. It's because of EPO. /thread

Frank May : Excellent content! Imagine how much trust you have to put in your heart rate monitor, knowing that if it doesn't alert you, you might die. I'd imagine some athletes saw it was easier to take some stimulants in the moment instead, and cocaine is a hard-hitting solution. Makes you wonder if athletes in that era got into cocaine use to at first just stay alive, but then to keep a high.

RGCastro7 : This was super interesting! I look forward to checking out more of your videos. Keep up the factual and excellent work, man.

Juan Marquez : Bep beep subbed, not fake

Patrick L : Great production value, excellent script! Make more.

Dale Drake : This is a brilliant video. Make some more bud a real gem!!!

red00tl : Very nicely done. I learned a great deal in a well-informed, persuasive presentation. I might challenge you to a duel of bike runs where there’s no hills, but until that time, keep up the good work. ;)

Target51 : I'm in, that was super cool :)

M4X THR0TT1E : LMAO no hills

Dr Manhattan : If people think that biking 100 miles on the weekend after sitting in a chair all week is a good idea- I would disagree.

Philadelphia Construction Engineering : AWESOME - mine is around 50 and below - but above 40 - when I sleep    Scary... to wake up and check... This is also why heart attacks happen in the a.m.... the ''start up''  time of the heart - to ''get it going''...

Baran Sönmez : Very good video! I hope you keep up the good work

Robin Hood : Mysteriously? Mid-Life EPOsis.

Dave G : Subbed. Do you know if Lance Armstrong has come out and spoke about this issue? I imagine he was well aware that he was at risk of having this happen to him too.

Lachezar Krastev : Great video - keep the good work!

Noi Jadis Cailleach : I love it. Looking forward to seeing more vids from you! Got interested in this cause up until around 5 years ago when i still had access to a heart rate monitor and was an active cyclist, i could ramp it up to 310 bpm. And when I'm not on my bike i noticed that i was always calm and relaxed. As well as super focused. I was always wondering why it was like that. Now i know why!

Toks Adesanya : Well done bro! Keep them coming. I had an ECG recently and have been referred to a cardiologist- I hope they still let me race and do Sportives

Sam : As a youth, I keep hearing my friends talk about cocaine, and the pleasure derived from it; Hearing the explanation of what exactly cocaine does to the heart, Christ, it would literally kill me. I don't want to touch cocaine. And if my friends are gonna do cocaine, I'll tell them that it will make the blood supply of their hearts spasm and cause blood clots, I think this is what people talk about when they speak of "infarct"

Jashen Thakur : Serious Potential in this channel , great content.

Stavers50 : Hey, keep up the videos! Try to reach a length of at least 7-10mins per informative video. High information + length will win you subscribers

WorldEngineer42 : This is such a riveting video!!

Titty Shepard : Well, that was just thoroughly enjoyable. Great presentation

Victor Obi : This was a really good video! Keep it up!

Jeffrey Scanlan : subbed! nice video!

TheDanzilla7 : Probably poisoned by poor commuters stuck behind the pricks cycling in the middle of the road half the speed of all other traffic.

10mmPig : GREAT narrator.

Madman5698 : Subbed

Martin G : Unfortunately quite a relevant video, when a young cyclist has died in France due to a heart attack

Der Eidgenosse : good video, much entertaining

Bad Motherfucker : Umm… My resting HR is 39. And max is 195. Damn, I’m gonna die, yeah?

Sniper Pro nerf mods : Uuuuh, how is the quality so high, I thought you were at 1.2mil not k, you are just outdoing your self man! Keep it up!

Jorge Yagüe París : How sad to buy yourself fake comments.

Gary Smith : very well put together and narrated, very informative, subscription earned

Luke Hoskovec : That was put together pretty dang well for being your 2nd video.

Melissa Hall : Well done.

WebbyCS : 'Dawg'

Jesse Compton : No. You can die from EPO though.

Alien On a Bike : My heart rate drops below 40 if I've been doing a lot of endurance training, but comes back up to the 50s after a two week break.

htdtr : Yo, I'll take that cycling road race challenge to stop you making videos!

RonMD : How dangerous is a resting heart beat, of say, 48 bpm? I've encountered a few marathon runners in the ER at their 60s/70s/even 80s who at the end, inevitably, needed a pacemaker due to extreme bradycardia. I don't know, I still think it's worth it, and I always get excited when I measure my heart rate from time to time and see it gradually become slower. The equivalent of a bodybuilder admiring his own muscles when staring at the mirror.

RonMD : This was incredibly interesting. Subscribing.

shaneweightman : Great video ,, I have started cycling and unfortunately had a stent fitted 9 months ago and on tablets to I believe reduce heart beat and blood pressure as well as blood thinning tablets ,,,I'm struggling to find what heart rate max I should go to or any info would be appreciated as I'm not good at research on the internet,, getting older ,, ha ha thanks Shane uk 🇬🇧

asgard69 : brilliant stuff!

Joe Blogs : Great video. Thank you.

Jernetta Smith : Wonderful work and I learned alot of interesting things watching your film...Waiting for many more films by you.

MSIGuy6461 : Please do a video on PED's! This video rocked.

Julia Walczak : Very informative video!

Timotei of Bollow : You had me hooked after the first few sentences. I was on a 24hr BP monitor after changing my diet to get off high BP pills (which worked) and saw that my HR drops into the 30's. I thought that was quite a good thing? After a long cold winter training for an Everesting (now completed) can you tell me when these bloody chilblains will go away?

Carl Blaskowitz : So interesting!
