Some of my peers are deep into running. I don’t get it. Running is sometimes fun for me but most often painful. Then I overheard one of them (the fittest) say to a budding runner that he [should] do mostly easy sessions. Okay what’s easy to him? He said that so slow that it can feel awkward and unnatural. What? Then I searched around and found out about Zone 2 and how you should do most of your work in that zone when…

If you don’t like running, find an exercise you do enjoy. Running isn’t the only cardio out there. If you’re jumping through hoops to force yourself to enjoy it, try a few other activities. Me, I can only get myself to run if I’m engaged in sports.

Or, if you're like me, find the one that you have to tolerate least. I find no exercise to be enjoyable. I tolerate a couple things like rowing or walking.

I think it will be very interesting to see how it plays out and has a lot of positive potential. I don't think it is very sustainable to have 50% of the population on a biologic medication to help self control, but hopefully it will help individuals and societies change norms.

Having to take a medicine every day for the rest of your life instead of just not stuffing your face is positive potential for you? Jesus Christ.

I was surprised how much cardio fitness improves by just losing weight. After losing close to 10 kgs I was able to run a 5K consistently 3 times a week and reached a respectable level of fitness for playing basketball

You literally feel lighter on your feet, like there's a spring in your step when you lose a good amount of weight. Imagine carrying around a 10kg weight with you all day.

> Sorry. But I'm an avid gym-goer and even I have to remind myself of the positive it's doing. We're not all the same. Maybe you're one of the people that for whatever reason exercise does nothing to - though I highly doubt it. I'm not sure what training you do exactly but to reap most of the benefits the workout should include moderate cardio work. I don't think going to lift weights for a 40-60 minutes with plenty…

Hmm, I've never felt any "noticeable" positive effect of exercise either. I didn't exercise basically at all for well over decade. But I felt fine, wasn't overweight or gaining weight or anything like that. But I decided that I should probably exercise, so have been for awhile now. Fortunately I have what appears to be a very high amount of self control so I'm able to just force myself to go exercise even though I ha…

Interesting. What kind of exercise do you do? and how do you define Zone 2 (there are many contradicting definitions out there)? I would try going a bit to zone 3/4 at times (of course while being careful not to injure yourself) not only to get the 'noticeable' positive effect, but also because it seems like you get bored/frustrated a lot in your workouts and it doesn't have to be that boring. Anyway keep at it, I hope you will enjoy it more and get that nice feelings everyone is talking about. Try noticing if your sleep is a bit deeper and better after hard sessions, how your energy levels are etc. For most people there will be improvement in those areas (you could be an outlier but I kinda doubt it).

Also - don't take it the wrong way but it's going to be very hard for you to notice anything positive about the whole thing if you're convinced you hate every minute of it. I'm not sure how you can get out of this mindset but I think it's important that you do. Or try different kinds of exercise that you don't hate.

I don't know about the guy in that specific incident, but in my case he was apparently healthy with no health complications, having had regular checkups on top of the mandatory ones (to be able to frequent a gym). This is the scary part for me.

How old was he? We doubled our lifespan from 32 to 75 from 1900 to now. In a 100 years, we changed the game. Once we pass 50, there is a lot of complex machinery at play including genetics, past history, diet, drinking, smoking e.t.c. to cause death.

In his late 30s. If he was, say, in his 50s or 60s this wouldn't have weirded me out as much. Could have been an anatomical defect or something like that, not caught by the regular checkups? Who knows...

It transfers to an extent. Lance Armstrong marathon PR is 3 hours from what I read, which is a great result for an amateur runner but totally unimpressive for a professional endurance athlete, let alone one of the best in history. I was actually a bit surprised that's the fastest Lance could do and to me it shows it doesn't cross over that well.

Not surprising at all. Vo2 in general is not great metric for elites and specificity is king. Which is why you rarely ever see elites cross train much

I wonder if running crosses better to cycling than vice versa, I think it might cross a bit better because running involves more (pretty much all) muscle groups. On the other hand there might be a lot of technique in cycling that takes a while to learn so idk.

Something similar happened at the gym I went to years ago, although I wasn't there when it happened. The poor guy collapsed while lifting weights. WEIGHTS. I kept reluctantly going for a few days before stopping. Then on the radio I heard about a guy collapsing while running on the treadmill, just like your fellow gymgoer, and it was the last drop in the bucket that kept me from doing any exercise other than slow to…

This baffles me. It’s well known that exercise is beneficial for overall health. Sure, some people die doing it just like some people die doing literally anything else.

Consider he was in his late 30s, which makes this even more absurd. For all I know, as you suggest, he could've also collapsed from doing heavy house chores or renovation, and it's something I've been careful not to overdo as well for that same fear.

I would suggest that in the next 5 years or so if ozempic and others don't turn out to be cancer causing or have more than awful side effects that we'll see a large drop in obesity, as obesity isn't an easy thing to change. Likely other competitors will come along and use a similar mechanism and Novo won't be able to charge $1000 a month for it any longer allowing 80-85% of those who are overweight to give it a shot.

As I understand, ozempic only helps you lose up to 15% of your body weight. Most overweight people are much more than 15% overweight!

Well, then once you've lost 15%, just start again..!

Define substantial. I find that incredible. EDIT: Now that I've seen the replies, I realize that this is from a very low baseline. I'm personally going to the gym four to five days a week already and my own cardiovascular fitness has not seen much of an improvement in many months.

It's the same with lifting and adding muscle mass. If you've never lifted before and you hit the gym consistently and have the proper diet, you will get some serious "newb gains." The first year can be amazing. But if you've lifted seriously for a decade, it's totally different. Muscle mass is very hard to add now. Cardio gains from a coach potato introducing a serious routine will be incredible. I went from not bein…

Why would you want to add muscle mass when you've lifted seriously for a decade?
