During the late 1950s, Hoffman's influence on Olympic lifting and his predominately Olympic-based magazine "Strength and Health" were beginning to come under increasing pressure from Joe Weider's organization. In order to combat the growing influence of Weider, Hoffman started another magazine, "Muscular Development", which would be focused more on bodybuilding and the fast-growing interest in odd lift competitions. The magazine's first editor was John Grimek. During the late 1950s and early 1960s, various odd lift events gradually developed into the specific lifts of the bench press, squat, and deadlift, and they were lifted in that order. Hoffman became more and more influential in the development of this new lifting sport and organized the Weightlifting Tournament of America in 1964, effectively the first USA National championships. In 1965, the first named USA National Championships were held. During the same period, lifting in Britain also had factions. In the late 1950s, because members of the ruling body (BAWLA) were only interested in the development of Olympic lifting, a breakaway organization called the Society of Amateur Weightlifters had been formed to cater for the interests of lifters who were not particularly interested in Olympic lifting.
