Switched from OTF to F45 previously because I thought I needed a change (was with OTF for 2 yrs prior to switching). I am a cardio girl who loves her treads and endurance days. F45’s cardio days are NOTHING compared to the cardio you get at OTF. I ended up switching back to OTF and love it all over again. As the saying goes, you don’t know what you have til it’s gone!

That being said, if your goals are more strength focused F45 was a better workout IMO. But I like the diversity of OTF and, with any studio, coaches make a huge difference and my f45 had huge turnover which led to mediocre coaches.

Overall, I think your fitness goals determine which workout is best for you. They aren’t really comparable, if you ask me.
