As a middle distance runner I'd like to be as lean as possible, but at the same time have enough speed to run really well at 400m/800m/1500m. I find strength training a really good way to build speed, but it often comes at the price of increased muscle volume.
Is there any kind of weight training that doesn't increase muscle volume? Or is it any exercises you can do to encumber the hypertrophy that weight training causes? What did Seb Coe do? I know he did a lot of strength training, but he was still a small and lean guy.
There is no kind of effective weight training for runners that does not stimulate hypertrophy; this is, after all, why you lift.
Seb Coe's weight training involved, among other things, moderately heavy loads in basic exercises. Seb Coe was "small and lean" because he was an ectomorph who was training very hard outside of the weight room; his best season (1981), not surprisingly, occurred when he was at his "most-muscular".
Your best bet would be to train effectively in a few basic compound (multi-joint) exercises such as squats, presses, deadlifts, etc. while avoiding isolation exercises.
