There seems to be some glitch in who can view the blog posts relating to this workout. Half the time I can see the entire thread while the other half I can not and it is directing us to sign in. This happens even though I am already signed in. There are also two sets of comments (on weeks 5-6 anyway). One set is viewable when you are "not signed in (according to the site)" and the other set when you are able to view the whole post.

 Thanks Mike!  We are looking into this issue and trying to fix it.

 We will keep you posted.

 It's not a 100% solution, but closing the window / tab and re-opening it again solves the problem for me.

It's fixed now. It appears as if there are two different threads:

The "Infamous TRX Workouts" - Weeks 5 & 6

and

Elite TRX Metabolic Circuits: Weeks 5 & 6

The second one is where the workouts are.
