Skipping the base phase or cherry-picking workouts can indeed be likened to a game of fitness roulette. The risk of injury and burnout increases, and the benefits of low-intensity work, such as improved aerobic capacity and muscular endurance, may be overlooked. These adaptations are crucial for sustaining high-intensity sessions and preventing fatigue.
In the long term, overlooking the build phase may lead to longer recovery times and diminished performance, as you've pointed out. The perceived efficiency of diving into high-intensity workouts might actually hinder progress and jeopardize long-term fitness goals.
The bare minimum in the build phase should include consistent, progressive overload workouts that maintain the structure and integrity of the program. This approach ensures a balance between intensity and endurance, setting the foundation for future gains and success in cycling.
