@Maid Marion yes I've changed my workout routines a few different times now. I'm definitely focusing way more on cardio trying to get at least 45 minutes to an hour of slow steady state cardio which science says is the best way to burn fat and depending on whether you're fasted or not you could also potentially use muscle as a source for your body's energy during those cardio sessions.
From all the research I've done it all seems to point in the same direction that you would pretty much do the opposite of what you would do to build muscle if you want to try and lose muscle. I don't necessarily want to lose all my muscle but I definitely would like to try and achieve a more feminine figure which I would have to lose some muscle size to do so. Obviously I can't do anything about my bone structure but soft tissue I should be able to manipulate to get in the ballpark so to speak.
So again yes a lot of the research suggests that the quickest way is to not use it because you lose what you don't use. A few of the people that I've been researching and trying to figure out what exactly they did most of them do say that they've basically wasted time trying to continue to weight train and use higher reps with less weight while still doing the regular lower body leg day routines with adding cardio and changing their nutrition.
They all seem to suggest that even with the lightest weights and higher reps any muscles stimulation is enough to keep that muscle from shrinking. It may shrink a little bit and it will definitely lose its strength but it won't shrink enough to see the results that they wanted to see and the results I would hope to see.
So I'm not quite sure if it's more based around my fitness and workout routines or if it's also based on hormones. Since I started HRT back in November I've really only ever been on estrogen and haven't really been on a anti androgen and when I was it was for a very short duration. I feel from my last lab work that my estrogen levels are exactly where they need to be but my testosterone levels are still a little bit high which is when my Endo decided to add progesterone and I've only been on progesterone since the middle of April.
So my question that I asked myself is once I get my hormone regimen where it needs to be and it finally gets my hormone levels where they need to be with estrogen being in the zone and testosterone being where it needs to be will I then see the muscle loss that I had hoped to see when I was trying to use lighter weights and more reps and trying to focus more on cardio and lower body workouts.
Or will it not really matter and it'll be how the individuals who were bodybuilders before transition said that it was extremely difficult to shed off the amount of muscle that they built over the years.
I know it takes time I mean for example it took me 26 years of working out and bodybuilding to get my body to where it was at before I started hormones and transitioning so I know it's not going to be anytime soon and I know it could potentially take years of trying to do whatever I can to get to that new goal I just don't necessarily want to add more years to the process trying to figure out what works and what doesn't lol.
As of right now I am training lower body three times a week with resistance or weight training. I am doing cardio 5 to 6 times a week. And I've been reducing my caloric intake.
I used to do lower body three times a week and have a push day for upper body and a pull day for upper body, while still doing cardio 6 days a week and focusing on nutrition and what I noticed with that was that I was able to be a little leaner or more muscular looking than softer. Which again I don't necessarily mind but I'd prefer to have that look in a smaller package if I were to keep the muscular athletic look.
Anyways I'm just kind of in limbo until the next month when I get my labs done and see what changes my Endo decides to make.
I'm definitely going to continue to work out regardless since that's been a big passion my entire life but like you said it's one of those things where it's most likely going to be trial and error to see what works and what doesn't and watching and learning how CIS women workout and train and most likely implementing some version of that.
