Benefits of Deep Stretching

Improve Your Posture
Improve Your Posture

Fix your tech neck, hunched shoulders, and sway back. Laptop lifestyle and phones are creating big imbalances, but with science-based stretching, you can stand up tall again and move with better biomechanics.

Lower Your Injury Risk
Lower Your Injury Risk

Tight bodies move with compensation patters that often lead to injuries. When you walk, run, and lift with better form, your risk of injury drops massively, simply because your body is aligned the way it was designed.

Reduce Joint Pain
Reduce Joint Pain

You’ve heard that movement is medicine, and for back, knee, and hip pain, stretching can have therapeutic, long-lasting effects. Stretching increases circulation of blood and synovial fluid, clears inflammation, and lubricates your joints.

Improve Your Sleep
Improve Your Sleep

Muscle cramps, body aches, and restless legs can make it challenging to get restorative, healing sleep. Deep stretching, especially when done right before bed, calms your nerves, reduces muscle tension and has been reported to improve both the length and quality of sleep.

Feel Like a Younger You

When you imagine an older person, you probably think of an old man shuffling across the room or rocking with momentum just to get up from a chair. Age and lost mobility often go hand in hand, but it doesn’t have to be that way.

The activities that you love most—travel, hiking, cycling, skiing, swimming—are all more enjoyable when your body is open and you can move freely.

Tight hips and a stiff back are awkward in bed, and while many are embarrassed to talk about it, lack of mobility can also affect your confidence and comfort in your private life.

Why Are You So Stiff?

Firstly, you sit too much. You already know that. Secondly, the most common forms of exercise—gym workouts, running, cycling—make you stiff if you don’t actively stretch. This means the fitter you get, the shorter your muscles become, which leads to huge problems as the years roll by.

You don’t need to quit your desk job or stop doing your favorite exercises, but you do need to add in some short, daily stretches to balance things out. The good news is that flexibility is accessible to anyone, regardless of age or starting point.

What Does “Double Your Flexibility” Mean?

If you are four inches from the floor in a Forward Fold today, the goal would be two inches by the end of the month. “Doubling” means “halving” the difference between where you are today, and your ideal bROM. Remember, our goal is functional range of motion, not contortion or tricks, so a doubling is very attainable.

My “Stiff Office Guy” Story

I was a stiff office guy with a desk job in New York City. One night, I went to a party where we had to sit on the floor—no chairs—and I was embarrassed how hunched my back was and how my knees were up off the ground. I felt like an old man. I signed up for a yoga class assuming that would help, but it was immediately apparent I was the stiffest guy in the room.

My hamstrings were locked up, my hips frozen, and my lower back would light up in almost every pose. If I kept going to class, for sure my body would change, but it would have taken 2-3 years. Honestly, I’m just not patient enough for that, so I started researching.

I spoke to fellow students, and then I also found dancers, gymnasts, and especially martial artists who were stiff—like me—but who became flexible later in life (the “naturally flexible” people were not interesting to me). Very quickly, I learned most people were using a similar routine, and later, I found that their approach aligned perfectly with the published literature around range of motion gains.

Here's what I learned:
  • Passive stretching outperforms all other forms if increased range is your goal.
  • Your nervous system plays a huge role, and you need to use your breathing to unlock your stretch reflex in poses.
  • Just like with strength training, time in a pose is crucial for progress, and you need at least two minutes in a pose to stimulate change.

Why Yoga Classes (often) Fail for Flexibility

Most yoga classes include strength, balance, breath, concentration, and flexibility. I love this about yoga, but if your goal right now is flexibility, a targeted practice with just one focus delivers faster results.

I learned this from a guy named Anthony. He and I were doing the exact same poses in the same classes, so I couldn’t understand why he was getting much faster results. Here's what he taught me:

Anyone can become flexible. There are very real genetic and age limits to muscle size, strength, and speed. But flexibility is different. It does not require youth or genetics, nor is it a metabolic burden for your body to maintain. This means anyone, with proper training, can regain basic range of motion (bROM).

Yoga classes are holistic, not targeted. When you focus on multiple things at once, the results for individual goals are slower. Since local yoga classes are holistic, it’s not the optimal way to train if flexibility is your current goal.

Junk food makes you stiff. I had a mild addiction to New York’s pizza by the slice, and Anthony helped me understand that yoga students need to eat to feed their connective tissues—and junk food wasn’t helping. Adequate protein and micronutrients provide building blocks and cofactors for collagen and connective tissue growth and repair.

About Me (Lucas)

Lucas Rockwood Pic

I’m a yoga trainer, TEDx Speaker, author, and corporate trainer. My published media reaches over 2 million people each month. I began teaching Science of Stretching in 2007, and it has since been practiced by more than 180,000 students worldwide with certified teachers in 21 countries.

When I started practicing yoga, I couldn’t touch my toes, but within a very short period, I completely transformed my body and my life. It frustrates me that most yoga teachers do a great job of showing you how flexible they are, but they are lousy at explaining how they got there.

The Science of Stretching is a systematic approach to flexibility training that I developed after studying and comparing notes with some of the leading yoga teachers, physiotherapists, and movement specialists in the world. The truth is, experts argue about the best method to train flexibility, but what I’ve found is that for people who need flexibility—yoga students, gymnasts, and dancers—the consensus is the same.

For flexibility gains, you need to supplement whatever you’re doing with long-hold passive postures that target specific areas. When I teach, I also pair it with a down-regulating breathing pattern to assist in shutting off the body’s natural stretch reflex and encouraging relaxation and release.

Frequently Asked Questions

Yes, anyone can train for basic range of motion when they use a proper training protocol. I was a stiff office guy myself and used this approach to unlock my hamstrings, hips, spine, and shoulders.
We have students with back pain, knee problems, and even chronic conditions. Most poses are presented with 2-4 different modifications for all levels. You’ll certainly need to modify some postures, but don’t let that stop you.
More than half our students are in the second half of life. Unlike muscle mass, which has very real limitations in the second half of life, flexibility gains can be achieved at any age.
You can find everything you need in your house. It’s helpful if you have a yoga mat, a block, and a strap, but if you don’t have these, it doesn't matter at all. Household items like a kitchen chair, coffee table, and belt (from your closet) work just fine.
Eisenhower’s “President’s Challenge” of 1956 included a sit-and-reach test for flexibility and 20-30 second holds were suggested intuitively by coaches and physical education teachers. It typically takes at least 20-30 seconds to overcome your stretch reflex (often longer) so the intuition was not wrong but also not ideal. You’ll struggle to find anyone who has made big mobility gains through short-hold stretches. It’s just not very effective. In practice, longer continuous holds or combined short holds in sets are what deliver results as evidenced in dance, gymnastics, and martial arts for decades.
Yes, 15 minutes daily is the ideal flexibility hygiene routine. It’s possible to train for longer, and some students do, but we find people get the best results with a small, consistent commitment.
No, this is series of pre-recorded videos that you can watch whenever works best for you. We recommend following a video per day, for five days per week, over the course of four weeks. You will have lifetime access to the material and can re-watch any of the videos at anytime.
Yes, both. After you sign up, you’ll get immediate access to the program now and forever. You can stream the videos or download them. It works on any device, phone or computer, iOS and Android.
I (Lucas) do a weekly Q&A, so you can send me questions directly. You can also message me on Instagram. I’ve been teaching since 2003 and I work with students every day, so I’m here to help.
