I’m often asked for advice on [tag]softball skills and drills[/tag]. Here’s a simple coaching tip from Ken that will pay huge dividends with your team. 
This [tag]drill[/tag] is great because it can be done outdoors or in a gym.
For fielding, throwing and endurance:
2 [tag]softball[/tag] coaches (or players) plus player in the middle
Position appropriate distance
X1 ————————-P—————————X2
X1 hits (or tosses) a ground ball to the P who throws it back to X1, then P turns to face X2 who hits another ground ball to P, who fields it and throws it back to X2, then P turns and faces X1 again and repeats.
15 reps will be tough
20 reps will exhaust them
