Most Painful Lower Body Exercise?

Hello FB People!!!

How are you all doing? I hope everyone is doing well. I've been lurking around and it seems a lot of you have been doing well. Hang in there for those of you who haven't. We're (FB community) here to help however we can. 😊

So I was watching this workout yesterday (https://www.fitnessblender.com/videos/fat-burning-hiit-cardio-workout) and for those of you who remember I can workout right now. Although as I was watching I was remembering doing this workout and how much I loved it. The sweat and burning was all fun to be honest. Then a round of squat jacks came in and I could feel my thighs burning just watching. It made me think, "Geez squat jacks have to be the most painful lower body exercise. They're still one of my favorites." At least for me. My goal has always been to stay low when doing these.

What about you guys? Would you say squat jacks are the worst or most painful or another exercise? Maybe multiple? Is that painful exercise your friend or worst enemy?
