What best describes the difference between a modification and a regression in exercise selection?

• A. A modification changes the intensity or difficulty but keeps the same exercise.
• B. A modification changes the exercise, while a regression reduces intensity or difficulty.
• C. A modification increases load while a regression changes tempo.
• D. A modification uses different equipment, while a regression takes away an exercise.

Answer: (B)

The main idea here is how to tailor work by either swapping to a different movement or by making the same movement easier. A modification involves changing the exercise you perform to better fit the person’s abilities while still aiming for the same training goal. For example, replacing a barbell squat with a goblet squat or choosing a different variation of a press keeps the same general pattern but uses a different setup or movement. A regression, on the other hand, keeps the same movement pattern but reduces its challenge—like doing a push-up from the knees or against a wall, or performing a squat with support to lessen the load. This distinction explains why the best choice describes a modification as changing the exercise and a regression as reducing intensity or difficulty. The other ideas—tuning tempo or load, using different equipment, or removing an exercise altogether—don’t capture the clear difference between substitution (modification) and simplification of the same movement (regression).
