Summary of this:
Should I start boxing and transfer onto MMA later? Boxing doesn't utilize kicks but I guess it's a good starter. Your opinion please?
This is the best opinion ever so please don't waste it.
Join your Highschool Wrestling and Judo Team. If you are able to also enroll in Boxing then do that too.
Wrestling is a very good base for MMA and its FREE.
Judo is also a good choice, but I would recommend wrestling if not both.
Boxing is a very good base as well.
