In heightened emotional states, like one feels before competing, often you've gone into a threat response. You've done nothing wrong, it's actually very normal.
But many athletes try to think their way out of this state... which doesn't work. Bot because they're not "mentally strong" enough... but because they don't know what's actually going on inside their brain/body/NS when they're in this state.
That's why breathing is so NB. It's the
Many athletes want a silver bullet that can "cure" their anxiety. So they learn the tools and think okay, "doing box-breathing once or twice at practice is going to cut it"... and when it doesn't they throw out the whole idea or say things like "breathing doesn't work for me".
Now I want to to give your anxiety a rating out of 10. 1 being the lowest and 10 being the highest/most extreme.
Whatever rating you've giving yourself, I want you to take that number and plus ONE and think "I'm going to practice my breathing exercises for 8 minutes every day I train/gym for my sport"
Link it to your training session so there's already a schedule.
This is a rough estimate - but think of it like this... the anxiety/tight chest/feeling depleted exhausted even before you race needs to be combatted with just a little more (hence the plus 1 min) so that I can prove to myself/my body/my brain through conscious breathing... that my sport is not DANGEROUS... and that I don't need to feel as anxious as I have been feeling.
