How would anybody fit anything in around their lifting if they left that amount of recovery.
I question that you know anything at all thebird.
24 hours rest would be plenty. I've squatted M,W and Friday and done hill sprints Tuesdays and Thursdays with no ill effects and how did I get so I could manage that? I trained like that and then adapted. The only way you can adapt to a higher workload is to train with a higher workload.
If you enjoy running the hill, then run it, don't not do it because someone tells you you can't.
Don't worry about all this recovery and CNS bullshit, the average guy on here is in no danger of "frying" his CNS.
You could always do them after your squats and deads if you need more recovery time until you get used to it.
