@countrygurl32 You're not "too heavy" this idea that women need to be "small" is patriarchal and full of shit. Your muscles are growing because you USE THEM. They're getting the the size necessary to LIFT YOUR BODY OFF THE GROUND. I want you to watch someone in your sport, and notice how much muscle mass it requires to actually hold yourself up. Look at for example aerial artists, look at yogis, gymnasts etc. A LOT of them are NOT tiny some are but most are not. There is a fine balancing line yes between strength and hypertrophy, there's also a balance between flexibility and strength.
I bet your ass men don't feel bad about their clothes not fitting. Buy clothes that fit you don't make yourself fit the clothes. Clothing is supposed to be flexible because bodies change over time. Historically you made clothing to be expandable and contractable but now the stuff is so cheap we just buy it to fit the body. Thrift or clothes swap if its getting expensive.
Comparing yourself to "some guy" on youtube is just gonna lead to innacurate results. The physiology of someone on testosterone dominance is simply not the same as someone on estrogen dominance. And even with someone on estrogen dominance its not the same per person because every individual's hormone cycle is different depending on genetics and external factors (so even if you're taking external estrogen your individual physiology will react different than another person taking E). So unless you're taking T supplementation or have naturally high T levels your muscularity is probably not what's impinging on your movements.
I personally am training both for health and also b/c i'm dying to get into aerial silks starting next month. I need to hold myself up and also have flexibility and balance. I train all over my body but my next round is not focused on power but rather on maintenance of lower body strength increase of upper body strength increase of core stability and increased stretch in the ligaments while maintaining muscle engagement. The side effect is yes my clothes don't fit the same in places, yes I am technically "overweight by bmi standards" but I FEEL amazing my spine is straighter my core is more engaged I have better coordination and i'm happier. so yeah I bought more clothes and i'm bigger in the legs and shoulders but shit. I like it a lot! You will one day loose "attractiveness" privelege. But your training will always be with you.
Train for your sport. if your sport requires stability then train stability. Focus on improving the technique of your lifts rather than the volume. If your sport requires more mass in specific areas to lift yourself then chances are you just need more mass. If you're finding it hard to invert then focus on increasing upper mass rather than lower but don't NOT train your legs or you'll experience imbalance.
