A great starting point if you are thinking of Flippig your PE classroom. The team at http://www.teachpe.com/ have put together an amazing collection of resources for teachers and sport coaches. I particular like their YouTube channel where there are numerous drills for a number of sports including soccer (95 videos), basketball (50 videos), badminton (22 videos), and much more. It also includes over 150 free weight exercises for you to try with your students.
Flipping your PE class involve students studying the topic by themselves usually at home using video lessons. In the classroom, students tries to apply the knowledge by solving problems and doing practical work. This way there will be less instructional time and more active time. Students generally find viewing videos 'not' homework and I have found a few of them actually explore extra drills and games they can do, which means using this for SEPEP would benefit the quality of the lessons. For more information about Flip Teaching, read about it on Wikipedia.
Here is a sample of some netball drills from the website:
