People who sit all day--commuting & at work--get tight hip flexors (see video #10 for hip flexor stretch). In a layperson's nutshell, tight hip flexors reciprocally inhibit optimal function of the glutes. When the glutes are inhibited then the hamstrings functionally act as secondary glutes thereby eventually resulting in chronic hamstring strain and tightness.

The piriformis & the 5 deep external rotators of the hip are forced to take on the extra workload of the hip & become super tight from strain & scar tissue formation. This scenario can lead to back pain, hip pain, knee pain &/or foot/ankle pain.

Stretching the gluteus medius, piriformis & hip rotators optimally requires you to move along multiple angles as they are anatomically shaped like a fan & the bones of the hip are shaped like a ball & socket universal joint.
