Around a year ago they migrated to Google+, and were renamed 'Gymchats' at that time. These have a lot of advantages - particularly the fact that there's a permanent link to each discussion. You'll find a complete list here.
Now, we're getting ready to grow once more - to include a video of the interview alongside the text. They'll still be on Google+, and you'll be able to access them in much the same way.
We'll be posting the full details of the change over the next few days.
I also want to mention another change that goes along with this.
If you've spent much time on Google+, or joined us for some of the previous Gymchats, no doubt you've bumped into the incredible Kirk Fontaine (pictured above). In addition to being a Personal Trainer and Fitness Writer, he's taken part in the Gymchats from both the interviewer and interviewee sides of the fence. Greatly appreciated.
Kirk's now helping out by scheduling interviewees for future discussions. If you're at all interested in taking part in one of the Gymchats, get in touch.
