The club was founded on 1 May 1915. The ice hockey section was one of the founding members of the
Hovedserien in the
1934–35 season. On 30 October 1940, the club merged with neighbours
Dæhlenengen SBK, and the new name of the club was
Sportsklubben Trym. Due to the
German occupation of Norway, there was no activity in the new club before the end of
World War II in 1945. It was then decided that the club was taking back the name
Strong. Their greatest achievement was winning the
1. divisjon championship in the
1947–48 season. In 1952, SK Strong merged with
Ball- og Skiklubben av 1914 and
SK Spero to form
Grüner IL. ==Ice hockey==
