In boxing look at Muhammed Ali. Ali is arguably the best fighter ever. He could spar all day long while training for a fight, and this would carry over to his fights. Ali's intense training of long road work, bodyweight calisthenics, and skill work made him what he is, THE BEST! You can also look at 4 time NCAA Wrestling Champion and Gold Medal winner Cael Sanderson. Sanderson never lost a match while in college, why? Sanderson had tremendous skill, but his outstanding conditioning level was a main ingredient of him winning matches day after day. At every wrestling tournament Wrestlers tend to fade because of wrestling multiple times a day for an entire 2-3 day period, but not Sanderson. He looked fresher than any of his opponents, which was because he was in such outstanding shape.
