For my podcasting searches, I used www.podcast.com and after some searching for "fitness" in their search box I found some that were ehhh, okay. Then, I came across one for BeachBody Revolution which I found very interesting since I have been using the P90X workouts for the past year. I decided to subscribe and found some exciting podcasts to listen to.
These have been useful in terms of my personal interests, but I am not sure how much I'd be able to use them in my teaching career. Again, part of this has to do with teaching on the elementary level but I can see how useful podcasts would be for teaching on the secondary or collegiate levels.
