CAT Exercise Modifications & Progressions 2

Question 1

A participant with knee osteoarthritis wants to join a high-impact aerobics class. What is the BEST modification?

Accepted Answer

Replace all jumping movements with low-impact stepping patterns

Answer

Low-impact alternatives eliminate joint-jarring forces while maintaining cardiovascular benefits for participants with knee osteoarthritis.

Question 2

When progressing a beginner aerobics student, which variable should be increased FIRST?

Accepted Answer

Duration

Answer

Duration (time) is typically increased before intensity to allow the musculoskeletal system to adapt safely using the FITT principle.

Question 3

A student cannot perform a standing lateral lunge due to hip pain. The BEST seated modification is:

Accepted Answer

Seated hip abduction with resistance band

Answer

Seated hip abduction targets the same hip abductor muscles as a lateral lunge while eliminating weight-bearing hip stress.

Question 4

Which progression strategy is appropriate for adding plyometric elements to a class?

Accepted Answer

Master low-impact base movement, add arm drivers, then add vertical lift

Answer

Layering progressions — mastering the base, adding arm drivers, then adding lift — ensures neuromuscular readiness before impact loading.

Question 5

A pregnant participant in her second trimester asks about supine floor exercises. The instructor should:

Accepted Answer

Modify exercises to avoid prolonged supine positions after the first trimester

Answer

Prolonged supine positions after the first trimester can compress the vena cava, reducing cardiac output, so modifications are recommended.
