I've got a video of the plank which I used in the Fat Chic Slim 'around the world' weekly challenge...There are options for beginners and advanced people. You can make it a challenge by seeing how long you can hold it for in one hit (for me on average its about 15 mins, but remember, I have a big background in the fitness industry, so don't use me as a benchmark, 4-5 mins would be pretty darn impressive).

(I hope you're on FB....)

If so, log onto to FB and search for Fat Chic Slim - there are 2, they're both mine though, but go to the Group (we no longer use the group - so don't join that one, (its just the location where the plank video is) however you're all welcome to join the other FCS page). Click on the 'video' tab, and watch the video titled 'plank / hover'.

In the event you can't view the video without join - just send me the request to join and I'll approve it.

FYI - on you tube there are other challenge type exercises I had videoed for the Fat Chic Slim challenges I gave the girls - just type in Fat Chic Slim into the search field in you tube and take your pick !
