World's Greatest Stretch

The world's greatest stretch is a dynamic mobility drill that combines a deep lunge, a thoracic rotation and a hamstring stretch in one flowing sequence. It opens the hips, spine and shoulders at the same time, which makes it a popular warm-up before lower-body or full-body training.

Also known as: World's greatest stretch lunge, Lunge with rotation stretch, WGS

Difficulty: Beginner

What muscles does the world's greatest stretch work?

Primary movers

Hip flexors
Hamstrings
Gluteus maximus

Assisting muscles

Hip adductors
Obliques
Middle trapezius
Erector spinae

The hip flexors of the back leg stretch in the lunge, and squeezing the glute on that side deepens the stretch. The glutes and adductors of the front leg also open.

The rotation takes the upper back, obliques and chest through a larger range, mobilising the thoracic spine. Following your top hand with your eyes helps the rotation.

Shifting your hips back to straighten the front leg adds a hamstring stretch. In one sequence you cover the hips, hamstrings and upper back.

Move through the positions slowly. The goal is mobility, not forcing a deeper range.

Common world's greatest stretch mistakes

Rushing through the positions

You skip the stretch and lose the mobility benefit.

The fix: Move slowly and breathe in each position.

Letting the front knee cave in

It stresses the knee.

The fix: Keep the knee tracking over your toes.

Rotating only the arm

The upper back does not get mobilised.

The fix: Rotate the whole upper back and follow your hand with your eyes.

Holding the breath

It increases tension.

The fix: Breathe slowly through each position.

How many sets and reps?

Goal	Sets	Reps	Load	Rest
Warm-up	2	3–5 per side	Bodyweight, slow	As needed
Mobility work	2–3	20–30 s per side	Hold each position longer	30 s
Beginner	2	3 per side	Back knee on the floor	As needed

Use it before lower-body or full-body workouts, or as a mobility break during a long sitting day. Spend about 20 to 30 seconds per side.
