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.

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.

Answer:
There are 13 minerals used by the human body to maintain health
Explanation:
Minerals are micronutrients used by the human body to perform essential functions such as maintain heartbeat, producing hormones, etc. The 13 minerals used by the human body to maintain health are: iron, calcium, potassium, magnesium, phosphorus, sulfur, sodium, chloride, zinc, copper, manganese, iodine, and selenium, molybdenum, chromium, and fluoride.
Minerals such as iron and calcium are needed at higher levels compared to the other minerals as they are essential for healthy bones and teeth (calcium), and carrying oxygenated blood throughout the body (iron). The 13 essential minerals can be obtained from a healthy and well-balanced diet. However, deficiencies in some minerals might require supplements.
