Critique my Cardio session

[Obs]

Hello all. I wanted to get some feedback on my cardio sessions. most of them look similar to this - . Im wrestling with the idea of what zone I need to be in to burn fat. I've heard that you should be between 60 to 70% MHR. seems like I'm a bit above that very often but I have a hard time getting myself to back off. i almost feel guilty slowing down if I feel like I can keep the pace up, even if I'm at 80%. am I being counterproductive? any recommendations and critiques are welcome.

You're grinding it out. Well done. I'd get bored doing that much cardio and I definitely want to avoid the dread of getting in a cardio session. 30 mins is good and will allow you to hit it hard. I'd move the cardio to the end of your workout so you don't sacrifice strength on your lifts. HIIT works for me as I get tired of the long treadmill and elliptical grinds. I like 1 min jump rope, 30 secs break, 1 min battling ropes, 30 to 1 min break, kettlebell swings 1 min, 1 min break. 4 to 5 rounds of that and you have the equivalent of a 30 min treadmill session. start this one day a week and build from that.
