Hello. My name is Vyacheslav Komakha. I have coached since 2009 — I help people gain flexibility, health, and awareness through correct work with the body on flexderek.com. Over the years I have seen hundreds of disappointed students with chronic pain and injuries after months of failed training. They all made the same error: they believed classic passive stretching was the only way to become flexible. In truth that method slows the path to the splits and creates an illusion of progress. If you want to know how active stretching speeds the result and how to sit the splits without pain, injury, and endless regression, this article will change how you train.
What happens in passive methods: you sit, open the legs, fold forward, and ask a partner or coach to press your back. Or you hang in the splits under your own weight, teeth clenched. The muscles are in passive tension. You think you are working flexibility. You are fighting your own physiology.
Muscle spindles and Golgi tendon organs protect the body from tears. When you force an unready muscle with outside force, the myotatic reflex fires. The brain sees a threat and orders: “Contract the muscle to save the joint.”
On the session, under a coach’s pressure, you dropped lower. The next morning you wake wooden, stiffer than before class. That is the regression syndrome.
You enter a loop: stretch through pain, get micro-tears, form micro-scars of connective tissue that barely stretch, and flexibility gets worse. Months pass. You stand still.
Without nervous-system control, load shifts from the muscle belly onto tendons and ligaments. Muscle has blood supply and can recover. Ligaments and joint capsules barely get direct blood; they are dense collagen and are not meant to stretch.
Stretching ligaments makes joints unstable. That is a path to hernias, protrusions, dislocations, and chronic pain. Passive work without antagonist muscle engagement wrecks the body from the inside.
The alternative that works, confirmed by sports science and coaching: active stretching. You reach maximum range only with your own muscle force, without outside help.
When you do active drills, the nervous system controls the process. The brain does not see a threat in a movement you make yourself. Instead of a protective block, it allows the muscle to lengthen. That is the safest, fastest way to rewrite the body map in the brain.
Active stretching rests on reciprocal inhibition: when one muscle (agonist) contracts, the opposite muscle (antagonist) relaxes at the neurophysiological level. The brain itself orders a release of what blocks the move.
To stretch the hamstrings, do not just fold passively toward the toes. Contract the quadriceps and iliopsoas hard to lift the leg. The hamstrings then relax on a spinal signal. No fight — just mechanics.
Many think flexibility is softness and limpness. Functional flexibility is strength at end range. If you can sit the splits only when someone pins you to the floor, but cannot lift the leg above the waist with muscle force, you do not have flexibility. You have unstable joints.
Active stretching builds active flexibility. You lengthen the muscle and teach it to be strong while long. The brain allows deep range only when it trusts the muscles can hold the joint there and bring it back. Strength creates safety. Safety creates flexibility.
Drop “endure pain for the result.” Learn to feel the body.
Forget passive seated folds. Lie on your back, lift one leg, knee at 90 degrees. Hold the thigh vertical with the hands. Then actively straighten the knee, sending the heel to the ceiling with a conscious quadriceps contraction.
