Today was my second trip back (the goal being twice a week). As I expected, it's actually very easy for me to get my heart up to my target rate (above 150), since I'm all out of practice with getting exercise. My legs and arms are feeling good about getting worked out - a little tired and rubbery, but "hey! I'm alive!" which I like. I managed 40 kilos on tricep curls and about 15 or 20 with the rhomboid machine I use to try to work the knots out of my back, and I can keep up a good rate on the base level on both the step and the bike machines. To top it off, I found a Charles Stross short story in the SF compendium ("The Mammoth Book of Best New SF 14") I brought with me, so I was feeling fairly well entertained (important as boredom is my number one reason not to go to the gym).
My goal these days is just to go twice a week, not three times, and try to manage a round of Pilates during the week. That way I can still do the Holborn Walks on Fridays (tomorrow: Fantastic Buildings, starts at 1 PM from Holborn Station) and elementary school French tutoring on alternate Wednesdays and not feel like my week is so painfully crushed for time that I can't meet a random friend for lunch. And I think the effects will still make it worth the time. A heart monitor watch would be good for me, though - shoulda got one ages back.
Tonight we're going to see Peer Gynt at the Barbican ... I just need to get out of here on time!
