Xert is a new software system that models fitness based on multiple parameters beyond the traditional single parameter of functional threshold power. Its potential for a higher level of individuality in training analysis, tracking and workout planning is well suited to cyclists.

In WKO4, iLevels are individualized training intensities and durations at levels above Functional Threshold Power. These are based on a rider’s own prior performance and capacity. How might we turn them into optimized intervals?

Xert is a new software system that tracks and predicts in real-time how much power you can generate at any point during a ride. Last April I explored the concept of MPA in broad terms. After a year of playing with the system, let’s explore the science underlying this concept and where it might take the world of power-based training.

Interval training involves high-intensity periods of work followed by lower intensity periods of work or rest that are repeated for a specific number of repetitions, determined by the fitness level of the individual. What are the things we should be considering to optimize intervals to suit our needs?

With more and more power monitors appearing on the market each year, the options for cyclists continue to expand. One of the newer players in the market is Power2Max from Germany. We test it and find a system that is superb in its accuracy coupled with ease of maintenance and use.

Pioneer's first power meter set a new standard for on bike pedal stroke analysis, but for 2014 the whole system has been thoroughly re-engineered and re-envisioned, coming out with loads of improvements and features. PEZ took the new system through its paces and further explored its unique capabilities for pedaling analysis.

The Pioneer SGY-PM900H79 power meter and SGX-CA900 cyclocomputer were developed with the Belkin ProTeam and feature completely independent left-right pedaling analysis. We review both and explore the new possibilities for improving your pedaling at the same time as tracking your power.

Pioneer’s brand-new SGY-PM900H79 cycling power meter offers new technology for real-time and very detailed pedal stroke analysis. So while pedaling may seem like the most natural motion to cyclists, and even I rarely gave it much thought, what I learned with Pioneer's pedaling analysis was an eye opener.

PowerTap, which has been making hub-based power measurement for cycling over a decade and continued to innovate, and we’ve had a chance to put their latest G3 hubs and Joule GPS computers through their paces.
