This video introduces you to some simple but deep work for the gluteus maximus & hamstring strength and helps integrate it with some simple core stability using postural awareness. The first part of the video (with the broom) is a great way to teach simple postural awareness. Start simple with the first phase or build intensity with all 3. The trick to this one is to take your time to do slowly (on yourself or your students, close the eyes if that helps) to maintain the integrity around the core & hip/leg muscles. This will be harder of course the longer you stay in each phase and the slower you go with bending the knees.
