Charlie has stated that if you must split your track and weight room workouts, that you should allow at least 4 hours between training sessions. What if this is not an option? If an athlete is forced to travel to another site for strength training, but can only do so within a short time frame, what will the phsysiological consequences be and how will they likely manifest themselves? Is this a situation in which the training will just not be ideal, or would this constitute a major fault in the training program?
Lift after practice, make due with whatever schedule you are dealt with.
