On Monday, Wednesday, Friday (early a.m. all three days), and on Saturday afternoon, I'm at the gym 75 minutes. Half of that is cardio (elliptical and treadmil, totalling 2.5 miles; half is weight-training, alternating workouts on back/biceps; legs/shoulders; and chest/triceps. On Tuesday, Thursday, and Sunday (early a.m.), I spend 20 minutes on the Nordic Trak, with the arm and leg settings both on high. Just about every evening, after work or after dinner, I also take a brisk, 2-mile, half-hour walk. I cycle on and off creatine.
At over 40 years of age, 5'7", 135 lbs., 12-percent body fat, 29" waist, 37" chest, my goal is maintenance. I can still wear clothes I've owned for 20 years.
But here's the kicker: when I look back at what it took to keep in the shape I'm in now when I was in my 20's, it was a walk in the park by comparison. I could get away with two visits to the gym each week, and a fraction of the cardio. Sheesh, that old Lewis Carroll line about having to do all the running you can just to stay in the same place never seemed more spot-on than it does now.
