Can lifting weights make you a more efficient cyclist, or is it simply a matter of building raw power without necessarily improving the economy of movement. In other words, if a rider can produce 400 watts on the bike, but it takes 500 watts of effort to do so, will weightlifting necessarily close that gap, or will it simply allow them to produce 500 watts on the bike, but still at the same inefficient rate.
Is there a point of diminishing returns when it comes to weightlifting for cycling, where the added power and strength no longer translate to increased efficiency, but rather just more energy expenditure. Or is it a matter of specificity, where the type of weightlifting and exercises used can have a direct impact on cycling efficiency.
Can a rider with a high power-to-weight ratio, but poor efficiency, benefit from weightlifting in terms of becoming a more efficient cyclist, or would they be better off focusing on other aspects of their training, such as technique and pedaling drills.
