i am glad to hear that double( a pretty good athlete) runs his best races at 170-180 pounds, i am a bit frustrated because i have put about 15 pounds in the last years, i am in 165 pounds now , and 2 years ago i was in 144-145 pounds, i have been training pretty good , so i dont know why i increased that much, should i worry about? or just train the best that i can and let the weight take care of itself? women think that i am look better but i think my running doesn't get used to that kind of weight? i did pretty good wotkouts on december and i think that i was around 160 at that point, so i dont know!!
