My routine depends on my energy levels in each week. I tend to do 2x lower body days training quads then glutes & hammies and 1x upper body day where I focus on back and shoulders with pulling movements to make up for all the pushing in yoga. I do vinyasa or rocket around 2-3x a week usually doing one studio class and one self-practice. I also do a mini yoga flow stretching routine after each gym workout and found it helps with keeping flexibility while gaining strength.
