This had been a noticeable hole in my Newbery Medal reading. I loved the characters and their family ties and the setting, but I don't quite think its various plot threads came together as Virginia Hamilton intended.
One of the selling points of this gym is that you would never have to wait for a machine. Yeah, not even at 4:45 p.m. on a Wednesday. I used a recumbent bike and then a stairmill for several minutes until an elliptical came up.
Precor elliptical, 45' + 3' cooldown until my pulse was under 120; 20/20 incline; 5' at 11/20, 25 at 12/20, and 15 at 13/20 resistance; and 5660 strides or 125.8 spm. The machine reported a figure, generous I'm sure, of calories burned at 618, but maybe that number is not impossible: it doesn't count arms, and I pump mine continuously. It's been a while since I've used handweights, though.
