I google-imaged it and from what I can tell, Cath has a "Power Tower" that is used for pull-ups & chin-ups (both use the adjustable bar towards the top of the tower), push-ups (uses the adjustable bar towards the bottom of the tower) and can be used when you are on your back on a weight bench and do chest presses (the tower will catch and hold the barbell for you).
It doesn't look like it can be used as a leg squat rack (doesn't look sturdy enough IMO), so that must be a separate item. I can't find that anywhere.
I still can NOT fine either item on her webiste and can't find a retailer who sells her exact items.
So anyone who knows where I can get this AND THE APPROXIMATE PRICE, please pass along the info.
