Charlie’s way was to lift after speed. That way, you maximize the recovery time before then next major CNS hit, and you know how tired you are after the speed session, and can adjust your weight workout accordingly.
If you lift first, you MUST hold back on the weight routine. If you lift hard, and THEN have a hard track session, your CNS can be cooked for days (this is the negative side of the HSI approach that you don’t get until you’ve been there, done that).
The other way, which I actually did last year and this following Bolt, is to have a part in the offseason where you emphasize weights specifically. Then, as you phase in the track intensity, you phase down (not out) the weight load. This wasn’t the CF way, but keep in mind that at least those big bench numbers for Ben that you read about around here (something like 2X10X365) actually came when Ben was injured.
