Which would NOT represent an increase to the exercise challenge for a participant seeking a greater challenge after mastering the baseline exercise?

Which would NOT represent an increase to the exercise challenge for a participant seeking a greater challenge after mastering the baseline exercise?

• A. Increasing tempo
• B. Decreasing rest interval
• C. Increasing base of support
• D. Increasing range of motion

Answer: (D)

The idea being tested is how to progressively make an exercise harder once the baseline is mastered. On a progression, you typically raise difficulty by making the movement more demanding in a few reliable ways: you can increase the time the muscle is under tension (tempo), shorten recovery between sets (rest interval), or demand more stability and control (by using a smaller base of support or by adding load and reducing external support). Among the options, lengthening the range of motion doesn't inherently push the effort level upward in the same consistent way as the others. You can move through a larger range with the same weight and the same speed and technique, so the overall challenge isn’t guaranteed to rise. In many progression schemes, increasing ROM is a possible variation, but it doesn’t by itself ensure a greater challenge the way tempo changes or reduced rest do.
