How can he bulk and peel so fast and so efficiently and while maintaining so much muscle mass, while guys like Trey Brewer and Kulco can't seem to do it and have been competing for longer? 
He probably has a better muscle mentor who has taught him how to really dial it in. Gotta give him props--he looked awesome!
Nah, both Brewer and Kucklo are very lean. It has a lot to do with genetics. Yes Seth may be
slightly leaner but it's genetics how your skin sits on your muscles, how thick the skin looks, and so on. How much water you retain is somewhat genetic too. Brewer and Kucklo could do the same exact program that Seth does, or have the same trainer, but they wouldn't look the same. Genetics.
