Utilize Compound Movements

How you perform an exercise is perhaps the most important dynamic in building mass. If you want full, hard bulk, do not isolate. Instead, use what Dave Draper calls 'body thrust' to compound the involvement of all the muscles in the area. Also, don't fall for the theory that cheating robs you of separation. On the contrary, it augments the compound benefit and builds even greater size so that there's more muscle in which to carve separations.
