I can't even remember how I first got subscribed to this, but I've attended several teleseminars from
http://www.askthefitnessexpert.com/
Kyle Battis is the host and has different fitness experts on all the time. It's live, so you get a shot at actually asking questions, too.
The first, was Alwyn Cosgrove. The latest one that I attended was with Christian Finn. Both were excellent!
I encourage you to sign up for the newsletter, so you'll get the invites.
I don't know if it's too late, but Josh Henkin will be discussing sandbag training, among other things, come Wednesday night.
I think you can sign up for this teleseminar directly at
