Apologies if this has been asked before!
My workouts currently consist of cardio plus a regular (4-6 days/week) yoga practice. I do Bikram yoga, so it is a very intense 90-minute class, with a lot of holding poses, etc.
My question is, do I need to add additional strength/weight training on top of this, or does an intense form of yoga like Bikram, Ashtanga or Vinyasa provide many of the same benefits? I am interested in muscle tone, the extra caloric burn that muscle provides, that type of thing.
Thanks in advance for any input!
