My coaches try to get me to do harder skills that are for level 9, but for like 2 weeks I haven't been doing level 9 skills since I have a meet this weekend. So I guess I am just doing it once in a while.It really depends on how well you can do your level 8 skills and what your competition schedule is. If you've got a meet next week, you probably want to work on you level 8 routines. If you don't have a meet for a while and can do your level 8 skills pretty well I don't see a problem with working some level 9 skills. What does your coach have you working on? I'm sure he/she is planning your workouts to get you ready for your meets and to move up.
I am recently trying to do harder skills that are level 9 material and I am only in level 8. Should I keep doing the harder skills so that I could be prepared for level 9 or should I just focus on my levels skills?
