New to F45: not feeling like I’m getting enough time for each workout?

Not sure if it’s a me thing or this is just the nature of the workout. I did hammer the other week and was going to go again but I see it was hammer again. (I also did a couple other workouts but don’t remember the names and seemed very close in terms of the timing). I just don’t feel like 30-45 second is enough time for each exercise? After the workout I’m like don’t feel like I did enough? I only do strength classes and only a handful of total classes. I’m postpartum so I’m still getting my strength up and I’m coming from Orangetheory where there’s just 10 min and they say do x sets of these 5 workouts until time is called. Anyone have advice? My goal is fat loss! I also am trying to run 1-2x a week when not doing f45.

(PS I’m new to the workout so please don’t downvote me)
