What is an optimal result?? Workouts blend into each other, so you have the sprint, then weights, then… etc. So the question now becomes, is it better to maximise weights after speed, or is it better to go with the “full glass” theory, which is that you do the weights that are possible based on what has already been done on the track? This goes back to the basic question of how strength is achieved. Do weights make you better on the track or do high quality track sessions improve your lifts and those lifts set up a stimulus that benefits the next track session?.
If you can, get the weights lecture series from the site store to get the full picture.
I want just ask something,my question is if i do track and imediatly i do weight how i will recovery?For me the track training is more important and i want to recovery good after track,tell me if you can?How you training with Ben,because Ben is one of the most powerfull sprinter he have very good muscles and very big strenght?Thank you very much Charlie 
More you train, more you need recovery… Nutrition suplements, enough sleep, massage If you are not profesional athlete, you can’t duplicate pro training… You must train in smart way…
We talking with Charlie for this how the weights make help you on the track,i mean how maximum lifting make help you and really need a full energie recovery after track training to lift the weights imediatly after track.If you have a rest between track training and weight training,you recovery and make lift weights strongly but how this help you on the track the next day and really weights help you on the track?Allan Wells not lift the weights but have 100m PB10.11 I thing…!?.Nutritional,massage,ice bath and suplements are very important for good recovery I know this!!!
That is why the weights are planned around the sprints. You take more of an autoreg approach within each training session. Whatever energy is left from the track is devoted to weights, but always ensure that you use them stimulate for the next next session. In other words, you would plan for a specific goals throughout a mesocycle and the microcyles within it, however when it comes to the specifc training sessions wihtin those microcycles, the work performed is determined by what took place on the track.

There can be some big advantages to doing weights straight after speed. For example my personal experiences are:
After short sprints 30-50m, weights feel lighter & I will use the oppurtunity to push the weights up to higher levels.
After special endurance 200-300m X 2, weights feel CRAP, legs are shaking etc, so I go very easy.
After tempo weights are at normal levels.
