adrain,
yes the more muscle you have the heavier you get, as they say it weighs more than fat. Power to weight ratio is king in the sprints.
The method of my training however means that I will have maximum strength for muscle volume, unlike the 'deforming' process used in body building. This way you can have realistic goals based on strength rather than how you look in the mirror.
The principle is basically to tear the muscle fibre in larger sections at once rather than tearing it in smaller sections in lots of little places. This means if you train your quads on one excersie you do not go and train them again for a upto a week.
The Do's and don'ts
*Do train heavy, aim for 6 or fewer reps per set.
*Don't do more than 2 heavy sets, even 1 might be ok.
*Do allow your hart rate to drop to 'rest' between sets.
*Don't 'warm up' with a cardio focused workout.
*Don't do ANY weights the next day or any day until you are satisfied your trained muscle groups have recovered. None of this do back monday, chest tuesday crap.
* Don't "hit your muscle from every angle" in the workout. Pick 1 excercise eg; leg press not legpress then squats then extensions.
* Do REST alot. Allow time for FULL recovery.
The best thing about this workout strategy is that it works well on even a crap diet (works even better with a good diet) because of the recovery principle.
