The principles of weight training have not changed over the years.. it´s about pushing more weight and PROGRESSION..sure you can do more reps/superset...etc,etc...but a plate loading Dumbbell is so much more versatile. I have had years ago great results from 2 plate loading dumbbells and a flat bench. I really loved the workouts i did with this very basic set up..the point being..it was progressive resistance and overload.
