You can set precise zones for recovery, endurance, and threshold work based on that 150W figure.

In cycling, an is generally considered a solid starting point for a beginner or an "untrained" cyclist, particularly for males, while being closer to a "trained" benchmark for females. Understanding the 150 FTP Benchmark

Retesting every 6–8 weeks allows you to see tangible improvements and stay motivated as that number rises.

To truly gauge if 150W is "good," it should be viewed relative to your weight. For example, if you weigh 60kg, 150W is 2.5 W/kg, which is a respectable level for a recreational rider. Why an FTP of 150 is a "Solid Feature" for Your Training

Anyone start with a low FTP (under 150w) and where are you at now?
