Progressive Overload
Progressive overload, the gradual increase of training stimulus over time, is essential for continued strength and muscle gains. In the context of weight selection, this involves incrementally increasing the weight lifted as strength improves. This can be achieved by adding small increments of weight each week or session, or by increasing the number of repetitions performed with a given weight. For example, a lifter might increase the weight on the leg press by 5 pounds each week. However, progressive overload should not compromise form; increases in weight should only occur when the current weight can be handled with proper technique.
-
The Role of Repetition Ranges
Different repetition ranges serve different training goals. Lower repetition ranges (1-5 reps) are typically used for maximal strength development, while higher repetition ranges (8-12 reps) are more suited for hypertrophy. Weight selection should align with the desired repetition range. Heavier weights will naturally limit the number of repetitions that can be performed, while lighter weights allow for higher repetitions.
