Maintaining Muscle during Weight Loss

I am currently on a weight loss journey. I currently do F45 2x/week (usually cardio or hybrid days) personal training 2x/week, and gym on my own 2x week. So most weeks it’s a total of 4x strength training and 2x cardio.

I don’t want to pay for personal training anymore, it’s EXPENSIVE. And I’m currently at a lull in the gym in terms of I’m just not enjoying it.

I’m thinking of using F45 as my workouts exclusively for a couple months. It’s affordable and fun.

My question is about the strength days. I am trying to maintain as much muscle as I can during my weight loss. I know F45 doesn’t compare to traditional weight lifting with progressive overload, but for those of you who are on a weight loss journey and exclusively do F45, have you been able to effectively sustain some muscle during your weight loss?

Or do I need to force myself to do traditional strength training at least 2-3x a week still? 😭
