The average player spends ninety percent of a game without the ball. What activities can we practice without a basketball? Footwork and conditioning...everyone has to decide how much demonstration is necessary for those players motivated enough to work out on their own.
The "core" blocks of Coach Wooden's "Pyramid of Success"
1) Stance (teaching balance, defensive technique) common to many sports
2) Pivoting - some say it is the least taught skill
3) Jump stops (start without the ball, then add back). Key is to drop the butt a couple of inches to lower the center of gravity and prevent falling forward.
4) Jumping drills - jumping rope, line jumps (front/back), mixed jumping drills (below)
Excellent video with dynamic stretching warmup exercise and then kneeling tuck jumps and broad jumps.
Split lunge jumps
Core strengthening - "dead bug"
Alternate Superman
"Box jumps". For girls, I suggest starting with newspapers (or magazines) bundled with duct tape because they initially can't jump as high as boys (fact).
Body weight drills (squats, lunges, step ups)
5) Hip turns (for defense)
6) Blocking out
Defenders can't see where the coach points.
