if your aim is to use a lot of energy, dialing down the intensity significantly and working for a longer time is the way to go
basically all cardio machines at the gym are going to be boring as all hell, going outside and doing activities is a lot more fun
If you are having enough fun, even high-intensity can be maintained far longer than you’d think possible when doing something that’s engaging. Still, spending 1 hour in zone 4-5 is probably gonna burn less calories than a 1.5 hour workout centered on zone 3.
cardio as a means of losing weight has a downside in that vigorous exercise provokes a lot of hunger. make sure to combine with small sustainable changes in diet for best results
But what if you just work out so intensely, that you’re too tired to eat? Its funny to me that the body can have like a 4K calorie deficit for the day and still just be like “No food. That’s a problem for tomorrow. Sleep now.” Probably a case where ignoring your body is a good idea.
Spending an hour in zone 5 is not exactly what I would call a realistic endeavor, given that zone 5 explicitly is above LT2. Lower zone 4, sure, but you’re looking at a race effort at that point
I meant a mixture of 4/5 (like HIIT-style, I guess?) and part of the point was agreement that if you strictly care about calories burned, dialing down the intensity is increasing the time is far better if you aren’t limited primarily by time. Still can be fun trying to chase the 1000 calories/hour burn rate even if its not effective.
