My heartrate is down by 25 BPM to what it was when I first started at the end of each cycle as well. This was my main aim, to make sure my heart was healthier, so I'm very pleased.
Not there yet, but getting there, so I hope things will continue to improve :). I quite enjoy my little reading sessions in the mornings now, although I still hate using the weights, which I've just added back in now that the bike doesn't make me want to crawl away and die ::g::.
