I'm having stamina problems, i can run 4 miles in the moring with out opening my mouth I just breath in my nose and out of it. But when I hit the mitts spar I feel more tired than I should be. I started sprints
100mx2
200m
400mx2
200m
100mx2
Am I doing something wrong? Maybe i'm reathing through my mouth instead of my nose. Any suggestions?
