Well by the way you put the question it seems like there are supposed to be answer choices but, since there are none. I'll still try to answer the question as best as possible
1. Comparing yourself to others is a bad way of trying to improve self esteem
2. Overthinking and overworking yourself is a bad way to improve self esteem
3. Trying to raise confidence in yourself takes time so you have to be patient
And that's all I can think of right now but I hope it helps!
Answer:
there are many different nutrients our body can't produce, such as: omega-3,
vitamins, and minerals, just to name a few. But, I feel water would be your best answer. Yes, I know, surprising, but true.
My guess would be stretching in the leg she wants to improve. I have done this many times and stretching would be the best way.
You can go into a split and then lean as far forward as you can.
Another one is to when in the split grab your toes and pull up,stretching near the actual foot which then gives you more of a chance to lift your leg higher.
