- [Power Meters: The Complete Guide to Power-Based Cycling Training](https://www.thepeakline.com/blog/en/power-meters/): Power meters measure work in watts in real time. They replace heart-rate guessing with a number you can train to. This pillar covers FTP, the Coggan seven zones, Normalized Power, Intensity Factor, TSS, W/kg, and how to pick and use a power meter — with the math and the tradeoffs.
- [Strava how-to: analyze, fix, and get more from your activities](https://www.thepeakline.com/blog/en/strava-howto/): This hub shows what PeakLine adds on top of Strava: deeper per-activity analysis, GPS track repair, FTP estimation without a power meter, heart-rate and power zones, training-load tracking, segment hunting, and per-ride weather. Each theme links to a focused how-to guide and to the glossary entry that explains the underlying number.
