Help Convincing Coach

i see where you are coming from. but this leads me to a few more q’s, if you wouldnt mind enlightening me:

-i assume your use of bodyweight exercises isnt too much because a high volume of them (if not performed explosively) would develop slow twitch muscle which is essentially useless for any of these power/speed events?

-i bet you have football players who participate on your track team, and i know at least the football players at my school love lifting. do they see significant strength loses if they dont really lift for the 13 weeks of season, or is the running, bw and plyo stuff enough to maintain what they have (generally speaking)?

thanks again!
