You have to be really careful with conditioning as it will spike cortisol levels. When on a fat loss phase, especially if you are sensitive to overproducing cortisol (tend to retain water easily, feels flat when dieting, easily lose muscle and strength while dieting), you can actually hurt your body comp progress by doing too much conditioning work.
I suggest NOT doing conditioning and lifting on the same day when you are on a caloric deficit. So you have both lifting and conditioning / cardio days. The ratio of which depends on your priority (maintaining/adding muscle or losing fat).
