You asked me if it was better to walk on a treadmill or do the science. That's so true. That's right. And the answer is, I'll see if I can spit this out in 60 seconds. Your cardiovascular fitness is split into four different categories. Your fat burning capacity, your DO2 max, your mitochondrial density, and your ability to be able to tolerate lactic acid, aka the burn.

If you are just walking or just sprinting, you're not going to hit all those variables. For VO2 max, once every one to two weeks, you do a hard maximum sustainable pace effort, like a four by four minutes on a bike with four minutes of recovery after each. For lactic acid tolerance, you go hard and then you recover, but not for very long.

This would be like the classic Tabata set, 20 seconds hard, 10 seconds easy, eight times through, four minutes, boom, done. That can be a couple of times a week.

for mitochondrial density you go really hard then you recover for a long period of time this would be like five 30 second sprints with two to four minutes of recovery after each one the sprints are really hard the recoveries are really easy and then for fat burning capacity you could do like a 12 330 or go out for a long hike or or whatever but you need to be aware that cardio fitness is not just cardio cardio is technically four different things so if you hit those four vo2 max mitochondrial density lactate tolerance and fat burning capacity

and those are kind of like woven throughout your week, then you're going to get all of them. Now, if you're lucky enough to be a soccer player or a tennis player or lacrosse or one of these sports that has a lot of start, stop and endurance baked in, you're kind of getting all those from your sport.

But if not, you kind of have to intentionally program them in if you want the most bang for your buck, aerobically speaking.

I knew that. My wife with the high risk of bone density, weight training. If you're morbidly obese, endomorphic with a lot of fat sores, long slow fat burning walks. If you're... Getting ready for a triathlon, high-intensity interval training. So it depends.
