They don't have time
Really though, our lead coach has had to hand pick the 6 gymnasts she works with mainly, based on their physical and mental abilities. She is in the gym 25 hours a week with some of the girls and more in school holidays.
Gymnasts working with 'elite' coaches have to be able to make changes pretty much straight away, have the ability to work independently and be very serious and focused in the gym.
A struggling gymnast would be miserable in a group like this and would probably drop out of the sport.
There aren't enough hours in the day for an elite coach to work with struggling gymnasts separately to their elite gymnasts.
That's why there is more than 1 coach for most teams. Coaches all have different styles which suit different gymnasts better.
I personally work better with the 'slow and steady' gymnasts and still get them to a decent level.
