It was in a Les Mills Class……Just wondering if true. 6 Answers ActiveVotedNewestOldest 0 Michael0 Posted 0 Comments Hello Patty, Possibly…a special stage event, shooting a video or some type of promotion with an accent strobe to catch the eye? I cant imagine functioning in a dark environment with a strobe light..if that were the case. Not recommended… Sincerely, Michael You are viewing 1 out of 6 answers, click here to view all answers.
