Bob used to be all about the cardio. Now, he mixes it up and practices at least an hour of hot yoga a day.
"I came from that very cardio background," he said on the Rachael Ray Show. "It's like, to get the weight off, you've gotta get cardio, cardio, cardio. I don't necessarily believe that's true in all cases."
Sure, cardio has its place, but mix it up with some strength training to help you build lean muscle and burn calories at rest. And if you want to start practicing yoga like Bob, that will also help you gain strength and flexibility and reduce stress.
