M asks: “I really need some guidance. I recently purchased an exercise DVD series called T25. I think there might be some yoga postures included in the workouts especially the stretches. I am really not familiar with yoga, as I have never practiced it. I was wondering two things. First are you familiar with this DVD and if so, is it safe to do? Also, if it does contain some yoga, can I still do the workout but skip the yoga poses or alter them in some way?”
