@virtualhope Read through the wiki on r/xxfitness. I think you may be falling prey to some misconceptions, which are negatively impacting your ability to get the change that you want.
First, you cannot sculpt a human body. We are people, not pottery. Using and understanding the correct terminology is really important. It sounds like what you are looking for is more visible muscle definition. That means you need to decrease your body fat, which isn’t going to be impacted by your workouts.
You said in your post that you “only“ lost 3 pounds in three months with your last cut, but that’s a perfectly healthy and normal rate for somebody our height. As someone else has pointed out, your maintenance calories are extremely low for your described level of exercise. That suggests you may not have an accurate maintenance number, you have a health issue that’s causing a very slow metabolism, or you’re not counting your calories correctly. Using a TDEE spreadsheet or an app like MacroFactor can be really helpful to make sure that you have the correct maintenance number and you are correctly recording all of your calories. You also have to use other measures such as progress pictures. It is very possible that some of the weight you lost on your last cut was muscle, which would have decreased your muscle definition. You can’t have muscle definition without muscle. Most people are not going to be able to maintain muscle under 1500 cal.
The human body doesn’t build visible muscle differently from different workouts. Switching from weightlifting to something like Pilates isn’t going to change the way your muscle looks. You may just lose strength and have less muscle, but there isn’t different kinds of visible muscle. It all looks the same. I think it would be really beneficial to just focus on your diet right now instead of changing up your workout if you enjoy the types of workouts that you’re doing.
If you ultimately decide that you would prefer to have less muscle, then you could try changing up your workouts. At that point you would have to decide whether it was worth it for you to change a work out that you love in order to get a specific appearance. I personally prefer the way my body looked when I was lifting five times a week, but currently I’m focusing more on yoga because that’s what I enjoy more.
