Interviewer: Today we are talking with Sebastian Brosche, founder of Yoga for BJJ. Sebastian, you were 30 years old and could not touch your toes. Now you teach flexibility to thousands of athletes. What changed?

Sebastian: Everything. And nothing. I did not become flexible because I found some secret stretch. I became flexible because I stopped stretching wrong and started targeting the right areas for the right amount of time.

Interviewer: What is stretching wrong?

Sebastian: Most people stretch like they are preparing for a gymnastics competition. They hold splits for minutes. They bounce. They stretch cold muscles before training. None of that helps BJJ. BJJ needs functional flexibility — the ability to move through ranges under resistance, not to hold a pose on the floor.

Interviewer: What is functional flexibility?

Sebastian: It means your hip can open to 120 degrees while someone is trying to pass your guard. It means your shoulder can rotate externally while someone is framing against your neck. It means your spine can twist while you are bridging. Static stretching on the floor does not prepare you for that. Dynamic, loaded movement does.

Interviewer: Where should a BJJ player start?

Sebastian: With the four bottlenecks. These are the areas that limit 90 percent of BJJ techniques. Number one: hip flexors. Tight hip flexors pull your pelvis into anterior tilt, which loads your lumbar discs and limits your guard. Number two: hamstrings. Tight hamstrings prevent you from inverting, from triangles, from retaining guard. Number three: thoracic spine. A stiff mid-back forces your lower back and neck to compensate. Number four: shoulders. Tight shoulders get kimura'd, cannot frame properly, and limit your guard recovery.

Interviewer: How do you open hip flexors specifically?

Sebastian: The 90/90 position is the best hip flexor opener for BJJ. Sit with one leg in front at 90 degrees, one leg behind at 90 degrees. Lean forward over the front leg. You will feel it in the front of the back hip — that is your psoas and rectus femoris, the muscles that tighten from sitting and guard play. Hold for 90 seconds. Switch sides. Do it daily.

Interviewer: What about hamstrings?

Sebastian: BJJ players do not need full splits. They need 90 degrees of hip flexion with a neutral spine. The best drill: lie on your back, one leg up, strap around the foot. Pull the leg toward you until you feel tension in the back of the thigh. Keep the other leg flat on the floor. Hold for 90 seconds. The key is keeping the down leg flat — that prevents pelvic tilt and actually stretches the hamstring instead of the lower back.

Interviewer: Thoracic spine?

Sebastian: Most BJJ players are stiff through the mid-back from years of hunching in guard. The fix is simple: foam roller, mid-back, horizontal. Lie over it so the roller is at your bra line (or where a bra line would be). Let your head and hips drop toward the floor. Breathe. After 60 seconds, reach your arms overhead. This opens the thoracic extension that you need for posture, framing, and not getting your back taken.

Interviewer: And shoulders?

Sebastian: Shoulders are tricky because BJJ players often have loose front shoulders and tight back shoulders from all the pulling. The best drill: doorway stretch for pecs, 60 seconds each side. Then, with a strap or belt, take your arms overhead, then behind your back, then across your chest — mimicking the ranges you need for guard retention, framing, and escaping kimuras.

Interviewer: How long does this take?

Sebastian: Ten minutes. I do it every morning before coffee. 90/90 hip opener, 90 seconds each side. Hamstring strap stretch, 90 seconds each leg. Thoracic foam roller, 60 seconds. Shoulder doorway + strap, 3 minutes total. Done.

Interviewer: What about before training?

Sebastian: Before training, do dynamic movement, not static stretching. Leg swings — front to back, side to side. Hip circles. Arm circles. Gentle spinal twists. Then drill specific movements: hip escapes, bridges, technical stand-ups. Your warm-up should look like BJJ, not yoga class.

Interviewer: How long until someone sees results?

Sebastian: Two weeks to feel less stiff. Six weeks to notice guard retention improving. Three months to feel like a different athlete. The key is consistency. Five minutes a day beats one hour once a week. Your nervous system learns through repetition, not intensity.

Interviewer: What mistakes do people make?

Sebastian: Three big ones. One: stretching cold. Never stretch before you are warm. Two: bouncing. Bouncing triggers the stretch reflex and tightens the muscle. Three: stretching the wrong area. If your lower back hurts, stretching your lower back usually makes it worse. Stretch your hip flexors and hamstrings instead — they are pulling on your pelvis.

Interviewer: Any final advice?

Sebastian: Flexibility is not a gift. It is a skill. Like any skill, it responds to consistent, targeted practice. You do not need to be a gymnast. You need to be mobile enough to play your game without your body fighting you. Start with the four bottlenecks. Ten minutes a day. In three months, you will wonder why you waited so long.

Interviewer: Where can people find your routines?

Sebastian: I recorded a free 10-minute follow-along that hits all four bottlenecks. No equipment needed. No spiritual language. Just the movements that keep you safe on the mats. Link is below.
