Heart rate monitors are just a tool and you can get one that is VERY easy to use that offers basic functions. I've been using them for over 3 decades and have used some very sophisticated models. What they can help you do is LEARN what is really going on. Perceived effort can and often is different than REAL effort. But with practice you can learn what your intensities really are.
To the greater point of the article: slow-go cardio does very LITTLE in the way of fat loss. And unless you have some specific training goals, say, run a marathon, there is very little need to actually engage in slow-go cardio exercise.
One study showed that a research group compared 20 weeks of endurance training vs. 15 weeks of interval training. The results: While the aerobic/endurance group actually managed to burn more total calories during exercise over 20 weeks (logical they trained 5 weeks longer), the interval training group lost NINE TIMES more body fat. NINE TIMES.
More FAT LOSS in LESS time of exercise.

BTW - I am 53 with single digit body fat, can run a 3-hour marathon and 19 minute 5k, canoe 8 miles an hour, do 80+ push-ups in a minute, do 30-35 good chin-ups. I can do this BECAUSE I do HIGH intensity exercise, regularly. I also believe HIT with weights to be the BEST form of exercise there is, as long as it's done correctly.
