Whats the point of Zwifts training plans if theyre just going to spit out a generic 4DP test result and then serve up a cookie-cutter workout plan that doesnt account for individual variability in fitness, schedule, or goals? Is it really that hard to create a plan that takes into account the users actual power output, cadence, and heart rate data, rather than just relying on a one-time test result? And what about the assumption that everyone wants to follow a linear progression of workouts - what about those who need to balance training with recovery, or who have irregular schedules that cant accommodate a traditional 3-4 times per week plan? Cant Zwift do better than just regurgitating the same old training principles that have been around for decades?
