I don’t do NEAR as much gymnastics as your daughter but I still partially understand. I also have a few more, uh, curves than what is normal compared to the other girls in my gymnastics group and they’re all the same age as I am, 12-15 (I’m 13). I am not fat and I am getting more visible abs (unless I’m bloated), but by no means am I super lean or skinny. I’m normal. For reference, I am 5 foot 6in and 120lbs. Very, very typical (but healthy) weight for someone my height.
I have given up on trying to lose more weight because it’s just not going to happen. I have accepted that. All the girls in my family are a bit curvier and that’s ok. The point is I’m healthy.
I went through a HUGE growth spurt last year where I grew 6 inches and a heck load of other changes that every girl goes through , and that was the year I started doing gymnastics. Not pleasant, to say the least.
My question is this: is your daughter healthy? If so, it’s fine. I feel 100x stronger with a 28 inch waist as opposed to when I was starving and it was 25in . I also have ridiculously thick thighs and even when I lost fat from my stomach my legs were always a bit fatter. I also accepted that. There is nothing wrong with wanting to be the best, leanest, healthiest version of yourself- but accepting things you can’t change, even momentarily, is probably best to avoid feeling like crap about yourself.
Another reason she could be ‘sluggish’ is growing pains. My ankles hurt a lot as I grew taller, and so did my legs in general.
It will pass.
Also, you probably know who Katelyn Ohashi is. You know, the viral video where she got the perfect 10. Does she have the most athletic body ever? No. But Is she athletic? Obviously yes, nobody does a double layout without being athletic.
Seeing I don’t do intensive gymnastics I couldn’t really give any advice- this was just my personal experience.
Good luck to her!
