but the thing is... i'm not saying that i agree with him, i'm just putting another point-of-view out there for discussion
according to my exercise science studies take i partook in at university cardio 3 times per week for 20 minutes at 60-70% intensity is ideal for heart health
so what do you think is ideal for heart health cardio wise? and what do the majority of cardiologists say?
It's something you shouldn't round down and try writing off. If anything, do extra because it's not going to hurt unless you're an Auschwitz-looking cardio addict. The whole "don't sweat it" attitude is a dangerous one.
I don't believe in cookie cutter advice either. Myself, I try to get outside with my dogs and run around the hiking trails here. I live a bit of a sedentary work lifestyle being tethered to a desk for 8 hours at one job and a couple hours a day at another job I do from home, so any chance I get I like to go outside and run around. Even if it's just chasing my dogs in the backyard for 20 minutes. It's not something I think you can quantify exactly and I hate giving specific guidelines, but it's something you can easily titrate by looking at your waistline, what you typically do in a day and how winded or energetic you feel when you exercise. If you're sucking back wind like a vacuum, you could probably benefit from more.
The cardiologists I know just think people have abhorrent cardiovascular knowledge. I'm not an expert, but I at least try minding it which is a lot more than what others do. They tell me that they're seeing younger and younger people with a ton more arterial plaques, low HDL, high LDL and triglycerides, tons of fat, tons of edema, participate in many negative activities that destroy cardiovascular health including but not limited to smoking, blowing coke on the weekends and eating a shitty diet, etc. Nothing extraordinary or unknown, just things that people don't care to mind for some reason.
I want to be running around with my kids and grandkids. I don't want to be sucking on an oxygen tank because I was too obsessed with being swole and flexing my fatceps in the mirror everyday thinking I'm a sexy beast.
