Alexis Rocha is a 13-year-old boy from California，US．He weighs 147pounds （67kg）．But six months ago，he weighed more than 202pounds （91kg）．How did he lose all that weight in only half a year？
"One day，I was surprised to find that I weighed about 200pounds，"Rocha says．"I thought I had to do something．"
Rocha is from a boxing （拳击） family-his father and two older brothers are professional boxers．So he decided to start boxing．He began with simple exercises，like sit-ups and push-ups （俯卧撑）．Then Rocha started jogging（慢跑）．"No kid likes running，"he says．"I don't want to do it，either，but I have no choice but to keep on．"
Months later，Rocha joined a boxing club in his city．He is always the first kid at the club to begin exercising，and the last to leave with sweat （汗水） on his face．Every day he boxes for about three hours．
"Rocha works very hard，"says his coach，Hector Lopez．"It's surprising to see him lose the pounds so quickly．I've never seen anything like this in my 20years of coaching．"
Rocha is very happy with his weight now．There is a family photo in his room from 18months ago．"Each time I look at the photo，I laugh at myself．I was so big back then，"Rocha says．"I look 100times thinner and 1，000times stronger now．"
