This is only going to work to the point where you are providing enough cals & appropriate macros for what you are trying to do. If you're talking IFBB pro bodybuilding competition prep, keep in mind the end goal is to look a certain way at a certain time of day on competition day - i.e the last weeks are all about water drop, and you will be giving up muscle as you do this type of cut.
Generally a continued drop in carb intake is going to hit a point where you either start starving your body of sufficient energy source or you are intending to do a ketogenic diet with sufficient refeeds. You can't just perpetually reduce carbs and expect to have an energy source to support increased cardio or general energy demands. You either are gong w/ a carb-based energy source where you are eating sufficient carbs, ore you are doing a ketone-based energy source where you do refeeds but still getting sufficient cals from fats & proteins. Just cutting carbs is going to leave you going catabolic. And if you're not also translating the part of this cut "Olympia athlete cut diet" that is focused explicitly on the water drop, you're going to give up even more muscle because you don't need to get that far down for a show and water manipulation is only very short term manipulation anyway, where you assume you will do some sort of rebound when you're done w/ your target date.
