my pb is 11.75fat. i'm 22 years of age 5'8.5 170lbs at the moment, lowest i gotten down to was 162lbs. Lasted about 3 days, cause i was feeling lethargic and weak, then i ate some carbs and my performance went up, then BOOM 166lbs in another 3 days after that. If i focus to much on fatloss i lose focus of training, i dont bother at the moment, teh advice i got is good, and i'm thankful, i need the knowledge so i can gain insight in the future. Right now priority is training to get fast, which is whats happening.
Dude listen. Quit the carb counting bodybuilding crap. Eat your carbs. If you don't you will not have the energy to train. Don't eat too much food and TRAIN truly like a sprinter and you will not be fat. If you are very fat, if that is what 17% looks like, then you won't run as fast as you could.As Barto, who knows what he is talking about said, you WON'T be a very good sprinter with back fat and a belly period. You can't name one that is/has been. Find one even at a the collegiate level who has a belly and backfat.
If you are gaining fat just because it is "cold" then you aren't training right/hard enough.
