Spending many hours on the bike leads to a number of adaptations in the body, especially when it comes to muscles and how they act on the joints of the body. Because "Joint position dictates muscle function" this means that many of the muscles in the body will be put into positions on the bike, for long periods of time, that do not allow the muscles to work as intended or designed.
“While the e-bikes that have geometry similar to folding bikes are an exception to this, I DO see power-boost Mountain bikes and Road bikes as quickly becoming a way for coaches and athletes to better control training stress on scheduled recovery days or long endurance days, where cutting an athlete’s ride at a specific point may not be feasible (think Kilojoule rides, and taper Target TSS/Intensity Factor rides). In my opinion, this can be HUGE and can significantly boost riders performances, when done properly. “
The missing piece, when it comes to strength training, for most athletes, is the understanding that strength training (and cross training for that matter) should be focused on strengthening the body in movements that are NOT done in their sport, and which will lead to better stability and strength through the sports movements. ESPECIALLY when we are talking about strength training for cyclists and triathletes.
You may be thinking these changes are a bad thing, but in fact, this very mechanism of the human organism- adapting to the working demands we place on out body- has led us to be able to survive for however many thousands of years, as we’ve adapted to the stressors and demands placed on us.
Designing a proper Strength Program
Proper Strength Training for any sport begins and ends by looking at the demands the given sport places on the body:
-The movements and ranges of motion at the different joints necessary to achieve success
-Very importantly, the imbalances that said sport causes in the joints
-And the adaptations that the body makes in order to "get strong & efficient" in that sport.
