List the color coding of the Pilates springs from lightest to heaviest.

• A. Yellow, Blue, Red, Green
• B. Blue, Yellow, Green, Red
• C. Yellow, Red, Blue, Green
• D. Green, Yellow, Blue, Red

Answer: (A)

The colors are arranged from lightest to heaviest: yellow, blue, red, green. Yellow is the lightest resistance, great for beginners or lighter work. Blue is a step up, red provides heavier resistance, and green is the heaviest option for advanced or strong resistance needs. This ordering lets you quickly choose the appropriate tension for an exercise and progression. The other sequences would place a heavier or lighter color in the wrong rank, which doesn’t align with how these springs are standardized to provide increasing resistance.
