Since I started transition I have been hitting the gym doing HIIT cardio which helps burn muscle mass.

Why does HIIT burn muscle mass? I was doing HIIT for the opposite reason -- to increase muscle mass. HIIT can dramatically increase HGH due to lactic acid release which will stimulate muscle growth especially when paired with a high protein diet and weight training.

In my experience it was the slow and steady cardio most responsible for decreased muscle mass (compare a sprinter's body to a marathoner).

Still, i think a toned body is much more attractive than an overly skinny one, especially on a women.
