To be competitive at amateur boxing you will need excellent conditioning or endurance. Novice go 3 rounds of 2 minutes while open class fighters *fighters with more than 10 + fights go 4 rounds of 2 minutes. Eventhough these rounds are short both fighters are going all out because of that. To get the conditioning you need you would have to run everyday, 40 mins. spar atleast 3 times a week 45 minute sessions with 30-45 minute cardio workout. Its better to have endurance than explosive power
because dont expect to be knocking anyone out at amateur boxing. We wear headgear 12-14 oz gloves, While the pros go gearless and use 10 oz gloves. If you knock someone down you only score 1 point, while in the pros you would basically automatically have won the round. Each hit from the white area of the glove is a scoring blow so you could knock the guy down twice in that round and still lose the round................... My point is... throw allot of punches, and never let up.
