What is the world's greatest stretch?

The World's Greatest Stretch combines a lunge, a hip-flexor stretch and an upper-back rotation in one movement. It is an excellent warm-up before any workout.

The world's greatest stretch is an intermediate exercise and a isolation movement. Isolation exercises move one main joint, which lets you focus on a specific muscle, fix weak points and add extra training volume without tiring the whole body. You can do it at home with no or minimal equipment, which makes it easy to fit into almost any routine.

Muscles worked

The main muscles trained by the world's greatest stretch are the hamstrings, with help from the calves, glutes, quads.

Hamstrings (primary)

The hamstrings run down the back of the thigh. They bend the knee and extend the hip. Strong hamstrings protect the knees and balance out the quads.

Calves (secondary)

The calves are made of the gastrocnemius (the visible upper part) and the soleus (underneath). They point the foot and are essential for walking, running and jumping.

Glutes (secondary)

The glutes (gluteus maximus, medius and minimus) are the largest and strongest muscles in the body. They extend and rotate the hip, power sprinting and jumping, support the lower back and shape the hips.

Quads (secondary)

The quadriceps are the four muscles on the front of the thigh. They straighten the knee and are the main movers when you stand up from a squat, climb stairs or jump.

How to do the world's greatest stretch: step by step

1. This is a three-part stretch. Begin by lunging forward, with your front foot flat on the ground and on the toes of your back foot. With your knees bent, squat down until your knee is almost touching the ground. Keep your torso erect, and hold this position for 10-20 seconds.
2. Now, place the arm on the same side as your front leg on the ground, with the elbow next to the foot. Your other hand should be placed on the ground, parallel to your lead leg, to help support you during this portion of the stretch.
3. After 10-20 seconds, place your hands on either side of your front foot. Raise the toes of the front foot off of the ground, and straighten your leg. You may need to reposition your rear leg to do so. Hold for 10-20 seconds, and then repeat the entire sequence for the other side.

Benefits of the world's greatest stretch

• Opens the hips, hamstrings and upper back
• Great warm-up
• Improves mobility
• Takes only 2 minutes

Like all resistance training, the world's greatest stretch also contributes to the general health benefits of strength work: stronger bones, better blood-sugar control, improved mood and a higher resting metabolism over time. The U.S. Physical Activity Guidelines recommend muscle-strengthening activities for all major muscle groups on two or more days per week for adults.

Common mistakes to avoid

• Rushing
• Back knee collapsing
• Not rotating the upper back
• Holding the breath

Most of these mistakes happen when the weight is too heavy or when you rush. Film one set from the side with your phone. It is the fastest way to spot form problems without a coach.

Form tips from a trainer

• Step into a deep lunge and put both hands on the floor
• Drop the inside elbow toward the instep
• Rotate and reach the arm to the ceiling
• Do 5 slow reps per side

How to breathe

Never hold your breath during a static hold or stretch. Breathe slowly in through the nose and out through the mouth. Calm breathing keeps your core braced without spiking blood pressure.

Sets and reps by fitness level

Choose a load or variation where the last 1–3 reps of each set feel hard but your form stays clean. When you can do the top of the rep range for every set, make it harder: add weight, add reps, slow the tempo or move to a harder variation. This is called progressive overload, and it is the main driver of strength and muscle gains.

Easier and harder variations

World's Greatest Stretch for men and women

The technique of the world's greatest stretch is the same for men and women. The difference is in programming. Men often aim for more upper-body size and use heavier loads with lower reps, while many women prefer more lower-body and glute volume and moderate loads with higher reps. Both approaches work. Muscle responds to effort and progressive overload regardless of gender, and women typically recover a little faster between sets.

Use it as an accessory in any of our home workouts or gym workouts, or create your own plan with the plan builder.

Safety tips

• Warm up for 5–10 minutes before your first working set: light cardio plus a few easy reps.
• Stop immediately if you feel sharp, stabbing or joint pain. Muscle burn is normal; pain is not.
• If you have an injury, are pregnant, or have a heart, blood-pressure or joint condition, ask your doctor or a physical therapist before doing this exercise.
• Make sure benches, chairs, steps and bars are stable and can hold your weight.
