in the next 2 weeks get your cardio maxed out with a mixture of sprints and some longer runs. talking 50 M and 100, sprints. last week take it easy and some liight cardio, light work, pad work, low contact sparring. this should help your confidence as most for these white collar things have utter shit for cardio and it will give you an edge.

enjoy. remember it's why you're doing it. or should be.
