It all depends on how much time you can spend and what you want to get out of your yoga rotation. I practice yoga almost exclusively with DVDs. There is always some toning in each practice but at this point I don't find it conflicting with any strength work. I do occasionally experience doms from doing horse stance or inversions (core/back.)
Here is my current rotation (which is ambitious but what the heck I'm soon to be between jobs again, might as well take the opportunity now, while I have it.)
Sunday: Rest
Mon: AM: 30 min. Jog (steady state) + Cardio Core Circuit,
PM: Shiva Rae Flow Yoga for Beginners (relatively easy, you might have it.)
Tues: Step intervals (pick one or do some other workout.),
Wed: AM: 30 min. Jog + MMA disc (pick one.),
PM: Easy yoga 1 hour
Thurs: AM: Step Ckt or whole body
PM: 3 mile walk
Friday: AM 30 min. Jog + 25 min. Solar Yoga practice
PM: Lunar Yoga Practice
Saturday: Steady State Step workout (RS, Step Moves, Step Hits or Step Classics.)
PM: Advanced Yoga (might be a lower body/core workout.)
That all said, its a lot to do. Tell us more about your yoga collection and what other things you would like to incorporate into your rotation.
