If you're talking about the 10x10 program (that supposedly Schwarzenegger used way back in his teens) then it's an OK idea for some basic bodybuilding.
I could write about this topic for pages and pages, but it's already been written. I see a lot of people talking about the 5x5 program, the this n that, progam and so on.
The magic's not in the sets n reps of various exercises. For strength training, it's all about picking a couple compound movements (like deadlifts and rows for back for example) and then warming up and the working some heavy 1-3 rep sets of deads (where the last rep of the set is really tough and you have to use less than perfect form to get) and then doing some heavy sets of 4-10 reps for rows (again where the last rep of the set is really tough) and then finishing up with a couple bodybuilder type exercises like low cable rows or 1 arm dumbbell bent over rows and banging out a few sets of 8-12 reps each where the weight really starts to get heavy at the end of each set.
Pretty much anybody can get a solid workout in in about 30-45 minutes (not counting warm ups and cool downs) and you can increase your intensity (as your gains slow) by decreasing your rest time between sets, by adding weight to each set or by adding a rep or two to each set. Increase intensity over increasing total time spent usually avoids overtraining.
Again, there isn't a magic sets n reps combination that's the key to more muscles and strength. The magic is training to the point of exertion and fatigue that's intense enough to inspire the muscles to grow to accomodate the demands without training to the point of over exertion and fatigue where the body is overtrained and gets weaker from being too beaten down.
Stay Strong,
