Among the young sumo wrestlers lifting weights in the ring, 10-year-old Kyuta Kumagai stands out. At 85 kilograms (187 lb), Kyuta is twice the size of the other children his age and is so dominant that he wrestles, and beats, boys five or six years older. Last year, he was crowned the under-10 world champion, beating out competition from as far afield as the United Kingdom and Ukraine. His training regime, devised by his father Taisuke, is relentless. He trains six days a week, either at his local sumo club or lifting weights. He also swims and practices track and field to build up the flexibility and explosive quickness needed for sumo wrestling. Kyuta has been on the programme since his father entered him in a tournament while still in kindergarten. "I didn't teach him anything, he could do various things naturally," said Taisuke, a former amateur sumo. "There is a talent for sumo and he has that talent. He won the tournament. I thought he may have something special." A shy boy of few words, Kyuta's motivations are simple. "It is fun to beat people older than me."

Hungarian swimmer Katinka Hosszu blows a bubble ring at a training session in Budapest, Hungary July 15, 2015. Before she became 2014 World Swimmer of the Year and the first to pass the $1 million mark in prize money, Hosszu nearly hung up her goggles, frustrated that she failed to win a medal at the 2012 London Olympics. Instead, she adjusted her thinking and challenged the Olympics-focused training cycle traditionally followed by the sport's top athletes. Olympic medals are no longer her ultimate goal, just one of several aspects to her schedule, she says. As she prepared for the world championships, which are currently taking place in Kazan, Russia, she already had in mind the autumn World Cup series as well. Picture taken July 15, 2015.
