6 Groups / 6 stations / 7 minutes per station (2 rounds w/ short break between rounds for drill change)
Kids can carry water with them through the stations so it's readily accessible.
Note:
Some of the drills may move quickly depending on group size. I've added notes with ideas on how to vary or progress drills to keep the kids engaged and prevent burnout or boredom.
That said, confidence is built through repetition—so if the drill is working and the reps are helping, you can stick with it. Use your judgment at your station to run it how you see fit.
If you have an idea for an alternate drill, feel free to mix it up half way through the station.
