Another site link on the cards today, at the moment I appear to be suffering from a case of insomnia so as a result I will be spending some time writing some lovely words promoting the work of the great Raymond Verheijen and the concept of periodisation. The site that he leads offers lessons on various different aspects of fitness wether it be logical or practical usually in 60 minute nuggets, I highly recommend you research some of his stuff. Select the link below.
