The adjustable Nordic Bar easily clips and fastens on to any frame, gym bar, post or immovable solid object measuring up to 90mm in width. Slide the Nordic Bar around the post you are wanting to attach it and fasten the HGG moustache bolts in towards the post until the clamping pads are tight against the post. Please refer to this photo for further clarification on how to set up your Nordic Bar. We recommend kneeling on a padded bench for comfort while doing this exercise.
