Thank you for your comments and advice; it was very kind of you to give me those links. Alas, I live in the UK so I will have try some retailers over here.
I cannot wait until the end of my first month of PE! I am really looking forward to posting some gains. I know I should wait until the end of the month to measure, but I am just too impatient! So, I went and measured myself, at the end of my first week of PE: To my surprise/joy, I registered an increase of 1/8 inch increase in BPEL.
This may not sound like an amazing increase to some, but it shows me that PE works!
My life will be complete with an 8X6.
