Two 3.8-mile city rides.
Also,
Precor Elliptical, 20' at level 20 (100%) incline, resistance 12 (60%), with two 2-pound handweights for 15'. I have to go later at night so no one waiting compels me to obey the 20' limit.
Hack squats, 90 pounds, 3x12
Lat pull-downs, 70 pounds, 3x12
Back extensions, 50
I have never been into weights. But I must, must, must get into better shape, and that means resistance in addition to aerobic training.
