The World’s Greatest Stretch earns its name for a reason — it unlocks hip, spine, and shoulder mobility in one smooth flow.

As you lunge, twist, and reach, your glutes, hamstrings, hip flexors, obliques, and chest all stretch in perfect coordination. It’s the ultimate move to improve flexibility, performance, and recovery.

🔥 Learn how every joint moves and every muscle works with Muscle and Motion 3D anatomy.

Special thanks to Dr. Aaron Horschig from Squat University for the inspiration.
