This workout has really grown on me.
I agree the combo section is a bit lackluster, and I do not care for double-kicks which are used a lot in this section. But the other sections are a lot of fun to me.
I tried the first premix (can't remember name) that includes heavy bag work. When I got to the combo section, I just hit "next" to skip it. Hey, a nice feature of having no chapter points, is I only had to hit "next" once!
I don't have a heavy bag, but this section works great without one. It was short combos with no breakdown and including kicking and even a few burpees. It was definitely a bit more intense than the combo section.
I think the drill and boxing with glove sections are fun. The boxing section music is mostly rap/hip-hop music which I love for boxing, and the fake lyrics are less noticeable to me since I can't always hear the lyrics anyway.
I loved doing the workout this way. It ended up being 50 minutes with the stretch, leaving me some time to do some abs. Finishing up with this fun section instead of the more boring combos makes it feel like a better workout overall.
According to my heart rate monitor the intensity for me was exactly the same as KPC and HardStrikes. Which means it was moderate. Kickboxing always is. KPC was actually a lower avg heart rate, but it feels a little more intense but I think that is because it is longer.
Full disclosure, I actually really like HardStrikes, so my taste in Boxing/KB workouts is different than many people here. I'm kind of bored with KPC and I like the drills that she does in these last two workouts of this genre. (I also like all 3 of the STS MMA workouts, but those feel the easiest of all her workouts to me.)
