Do you think being on beat and following musical phrases should be a must during strength training classes? I am having a hard time to follow musical phrases when I cue for the correct posture and emphasize the importance of the performed exercise, talk about the muscles that we are working, motivate the class…etc.
in my opinion, there is no ‘must’ for anything at all, least of all strength training. We all encourage our participants to ‘listen to their bodies’, and have a group try to keep up with a tempo can easily lead to incorrect form, if not worse.
If you feel that music is necessary in your class, I would push it into the background. After all, you want your participants to listen to you as you cue for posture rather than struggling to keep up because of a beat. If for any reason you want a certain tempo to be followed, you can always cue it rather than having the music determine it.
Hope this helps.
