Softball drills and conditioning

okay so I am helping my dad coach a 14B club softball team...and I was wondering what kind of drills would be most effective to get them into good shape...running,hitting and fielding?

I have never done anything with softball or anything but its just simple kind of stuff... first off for running.. just have them run around the bases.. doing different things to each base.. like sprinting to one then lunging to the next and so on... hitting.. first teach them where the ball should be to hit it... and figure out your best pitcher or just have the couch through them balls until they like like 3 or so and then switch.. and for fielding.. in the beginning just split them in 2's or if one left out 3's and have them throw to eachother.. do normal throws to get them good at catching a ball thrown to them.. and then have them throw to the other person but throw it high to get them good at catching things like pop flys and then rolling the balls to eachother so they can get balls coming at them from the ground... hope it helps
