Most of us spend far too much time sitting and far too little time walking around and squatting the way humans and our ancestors did for millions of years before the modern day. Excessive sitting makes hips extraordinarily tight, which can affect posture, ability to comfortably perform certain movements and the amount of weight you can move in lifts like the squat or dead-lift. If you sit a lot at work or find you have mobility issues with deep squats or hip tightness with other lifts, try this quick hip stretching routine to keep that very important set of joints healthy.
GMB Fitness walks you through eight fairly easy movements and stretches to loosen up your hips. They thankfully include a stretch for the piriformis which gets very tight in a lot of people and can cause big issues in the gym.
