There is a danger getting caught up with numbers in the weight room. My primary point is that you can build the “strength” to lift 500+ with sub max lifting. The ability to express that strength does in fact require lifting circa max weights, lifting big weights is a skill and has a technical component just like any other movement pattern. However this improvement is exclusive to lifting because the rate coding is specific to the movement being performed.
Having the necessary strength to excel at sprinting and expressing that strength in the weight room are two very different things.
