For me, it depends on what I’m doing. In the mornings I always do yoga so my back doesn’t hurt. And just to stretch after sleep. No music there. Not relaxing, not upbeat, not even meditative. But in the evenings I usually train according to my plan from https://madmuscles.com/. It’s personalized, super convenient, and with an affordable subscription. Strength training I prefer to do with music. That’s when the energy really kicks in.
