Do you struggle to touch your toes? Have you been told it's because your hamstrings are weak, not because they're tight? If so, you're being gaslit. While your hamstrings might be weak, when it comes to flexibility, you have to train these tissues with stretching exercises as I’ll show you in this video.

Tight hamstrings impact your posture, your walking and running gait, and can even contribute to lower back problems. Since your hamstrings are involved in nearly all your movement patterns (think knee flexion, hip extension) if left unchecked, the progressive tightening of these tissues is the norm—but it doesn’t have to be.

Your hamstring range-of-motion is determined by two factors: your nervous system and the length of your tissues. The Science of Stretching is a targeted approach I’ve developed that combines exercise physiology research with best practices from yoga, gymnastics, and dance. It’s really effective at unlocking any muscle in your body, but in this video we'll focus on your hamstrings.

I’ll explain the three key Science of Stretching principles of practice and show you how to put them into action with a simple pose that targets change in the muscle fibers in your hamstrings. If you’re new to this this type of deep, passive stretching, remember to start slowly and ease your way into it. Let’s get started!

ANATOMY
The hamstrings are a group of three muscles located at the back of your thigh: your biceps femoris, semitendinosus, and semimembranosus. These muscles originate from the lower part of your pelvis and attach to the bones in your lower leg.

They are biarticular muscles, meaning they cross two joints (hip and knee) so they play a crucial role in coordinating movements when running and jumping.
When your hamstrings become tight, they reduce flexibility and range of motion, which can lead to discomfort in your legs and lower back.

    can we all appreciate that he ripped out his hamstring just to teach us how it works

    Your videos are excellent Lucas. A real lesson in clarity and great video production. The content for yoga and health is a bonus. I really enjoy both the very useful content and the quality of production. A rare thing. Well done!
  • @K-Fred
    Perfect material for where I'm at Lucas. Thank you!

    Science of stretching is good, I have it. I’d call it stretching that is intense as strength training. Make sure to start out using the modifications instead of jumping right into the full stretches. Most of us should focus at least as much on flexibility as strength training, if not even more. Work your weakness, especially most men who functionally need more flexibility, but they’re spending all their time on strength training at the gym instead.
  • After years being told I wasn’t able to do a forward fold and touch my toes because I had tight hamstrings, a yoga teacher suggested I incorporate a stretch that focuses on the lower, outside portion of my back. I stretch both sides and immediately get inches closer to my toes. My hamstrings were being sufficiently stretched all this time. My lower back was not.

    I absolutely adore how you get straight to the point with valuable information and no affectation. Your video on hamstrings has already helped me. Thank you. I can already feel the improvements occur through relaxation during the 4-minute pose.

    Amazing vídeo! Greetings from Brazil! 🇧🇷
  • @howarddavies782
    I've also heard of glute amnesia where your glute muscles go to sleep and leave all the work to the hamstrings which become over worked and tight. Great video.
  • @hiteshjain9617
    Very few videos explain the science behind everything they do, hope you keep up the noble work! Very informative and helpful, i am grateful
  • @thibod07
    Excellent video Lucas! Specially when you pulled your muscle out to explain something about it. This was so unexpected yet really caught my attention! Well done!
  • @anuraggoel101
    You’re such a good teacher! Very easy to understand
  • @adamtruitt2353
    Passive is quick, but effective for only a very short time and does very little to affect actual change in range of motion. Standing up from the stretching position will do more.

    I love your content Lucas, it's wall made, very concise, and well explained, while being relaxing and follow along. Can't do much better ! There is although the fact that no single mobility educator on YouTube or elsewhere says the same thing about stretching poses duration, or even relative importance of active vs passive mobility training. I appreciate the precisions you make here but still. I decided to go to research paper directly to make my own views, and they kind of contradict themselves too on optimal duration. Isn't then it a wrong statement you make about science of stretching being clear and resolved toward 2-5mn duration ? I tried to download your PDF to find studies reference but couldn't find any. Don't get me wrong, I'm not against your approach, I even found great benefices trying your way, and incorporated it in my mobility practice. But stating such clarity on what is best might be deceptive if it's not. I wouldn't stop appreciating your content with a more nuanced approach, clearly outlining what's scientifically validated vs what are you beliefs on the topics (which I'm happy to consider!). Cheers mate

    Thank you. Am glad I found this channel.
  • @maxdugger1409
    First video of yours I've seen. Love the simple yet scientific approach to stretching. Now I know why, ever since high school, stretching never seemed to work for me. 10min video fundamentally changed how I view/approach stretching. Thank you

    This content is so good
