The workouts that you do should be hard enough, but not too hard. Even when weight is slowly added, the workouts should still remain hard enough but not too hard. At the end of a year, your workouts should feel no harder than they felt at the start of the year when you were using twenty to forty pounds less on all your lifts, and at the end of five years, your workouts should feel no harder than they felt when you were using one hundred or more pounds less for your lifts. You start out with a moderate training stress and continue with a moderate training stress as weight as added.
