My answer is always the same when it comes to this question. Do the form of cardio you enjoy doing right now, and do not ever worry about what is being "burned." Calories or fat! It does not matter! Let's get clear on this one form of cardio does not burn MORE BODY FAT than the other. High intensity versus steady state cardio will simply use different energy systems, meaning they tap into different forms of FUEL.
High intensity work will prefer carbs as fuel.Where more steady longer aerobic work will prefer fat as fuel, especially once carbs are depleted.But don't confuse using fat as fuel with losing body fat. Doesn't really work like that! The only way to lose body fat is to eat in an energy deficit. Consistently consume less energy than the body burns and you will lose body fat slowly over time. That's very different than what energy source your body is using for cardio. If you are not in a calorie deficit, fat burning for fuel will not result in actual fat loss.
So what should you focus on if you are a woman over 35 who has fat loss goals?
Strength train to add and preserve muscle, and do whatever cardio method is actually enjoyable to you. Even if that is just a walk each day, short or long!
I can't stress this enough, these little details are not important for fat loss goals, and getting caught up in these kinds of details is a massive waste of your time.
Why? Because nutrition is the main driver of fat loss. Meaning you're eating the right balance of calories (and nutrients so you don't feel like 
) to keep you in the deficit.
