Just jab for the first half-round, remember to breathe.
Go through it in your mind, even practice your movement in the ring. Imagine your ring walk, getting in, everything. Get it square in your mind.
Don't get excited like your the next big thing, like what's the best ring music etc etc. sod all that mate - just know what you have to do.
Yeah breathing properly is a big thing for me! With numerous broken noses and the gum shield i need to get it right or I'll be gasping! I'll definitely be starting slowish, High guard, double jabs feeling out what comes back at me.
Yeah I ament getting carried away with the ring entrance stuff, just picked a simple song I like, I'll have a tonne of family/friends there so I wont need anything else to be getting me hyped up.
Its amazing though, I've played competetive sport at a high level for years now, but the level of concentration needed for boxing (even at novice level) is insane. Makes you appreciate just how good the pro's really are, even the bad ones!!
