Is This What's Called Cross Training?

Time is slipping by - not quick enough, in my book - here in the land of dust, heat and crazy mulit-national traffic gridlock! Work is busy but I am managing to get some training completed. I feel utterly out of shape and a complete OAP who is 'past it'! Basically, I do spinning, treadmill running and conditioning when I can squeeze it in. Also, recently, I have been doing some Ergo Concep 2 rowing. Man! I am a numpty on this machine! My 2k time is 7:37 - and that killed me! I had no idea what is a decent time and my form was, apparently, not good! After a quick look on the internet, it was clear that 7:37 is not good, even for a lightweight! Now a lightweight in the rowing world is 75kg. Now that seems more like a heavy weight to me! They should do a super lightweight! i reckon I must be around 65kg? Rowing sure suits the big strong guys, with long levers. Not sure That I would ever be a decent rower but the exercise is meant to compliment cycling; hence I may try and do some specific rowing training and aim to gett nearer to 7:00. At least cycling rewards a decent strength to weight ratio! Mind you, even that goes out the window when doing a spinning class! Must dash; got heaps to do! Best wishes to everyone managing to enjoy a race season!!
