I started - along with my friend - the programme on Monday and couldn't believe I finished it! Did the second one today and can't believe how hard it is. I have been walking since September and thought i was getting fit. I really can't see when i will come to a point where i will be able to run for 20 minutes non stop as i really look forward to the end of each 60 seconds to rest!! Did anyone else out there feel the same on beginning?
