During our visit to Columbus, Ohio for the 2010 Arnold Sports Festival, Nutrex conducted an "UNDERGROUND" photo shoot with one of the IFBB's hottest new Pro's Zack 'King' Khan and star photographer Robert Reiff. This is part 2 of this two-part behind the scene series. Remember, to prevent injury from fatigue in this rusty iron hot box we had to greatly limit the weight Zack is normally throwing around. Still this proved to be a completely draining workout which also included quite a few unorthodox and static exercises. Thanks again Zack and Robert for a job well done.
