The ones i listen to are, Heavy Muscle Radio, After Hours and Off Topic lol, they are the top three in that order.
The rest of the podcasts out there are pretty shite. I haven't listened to the new one on RX called "Sex and Muscle" but judging from the title it's probably shite.
I listen to them while at the PC/travelling/cardio.
Sorry i know getbig sponsors PBW but it is shite these days and not worth my time.
