The trainor, who happens to be a PHD Scotsman, working in Mass, emphasizes " core" workouts, which focus on building up a strong central system. esp. back and stomach muscles. The exercises are fairly simple, but he works me exceptionally hard weekly, to the point where I am exhausted at night. I supplement it with two more workouts a week.
Also my ability to touch my toes was awful, because of prior basketball without stretching. Improving this aspect gradually. Must stretch after every exercise.
My wife and I decided that, for both of us, the expense was worth it as an investment in our future level of activity. So far, it's been realized.
