absolutely. there is no point in cardio UNLESS you sweat hard and work to push your limits. if yr. trying to lose weight, lifting will help you of course, but cardio should be your primary focus. Don't screw around with worthless nonaerobic crap like yoga, pilates, etc. I see way too many obese women who rely on this sh!t for their only workout and wonder why they don't lose weight.
Not that guys usually fall for that pilates-works-you-out bullsh!t. I know babalu does yoga once a week (supposedly) but he also does insane hill runs along with all his pad work, grappling & striking etc.
