Hyperbolic Stretching Review: A Trainer’s Honest Take

Bend over to tie your shoes and feel your hamstrings complain? Stand up after a long day at the desk and feel like your hips are made of concrete? Tight muscles creep up on almost everyone, especially after 30.

Hyperbolic Stretching is a popular online flexibility program that promises better mobility with short, 8-minute routines. Its ads are everywhere, and so are the big promises about splits and dramatic flexibility gains.

In this review I look at what the creator publishes about the program, including what is inside, the price and the guarantee, and compare the claims with what stretching research actually shows. There is real science here, wrapped in some very optimistic marketing.

What Is Hyperbolic Stretching?

Hyperbolic Stretching, now marketed as “The FlexTense Method,” is an online stretching program. It gives you a library of short follow-along video routines, each about 8 minutes long, that you can stream on any device.

Creatine + HMB

Creatine is the most studied performance supplement there is, and HMB is aimed at protecting the muscle you already built. Together they cover strength and recovery without the pre-workout jitters.

The routines target specific areas: hamstrings, hip flexors, front splits, side splits, lateral hip opening, forward folds, back bends and upper body. There are also gentle morning and evening flows you can do in bed, plus maintenance routines.

The core idea is to use muscle tension to help muscles relax into a deeper stretch, rather than just holding a passive stretch and hoping for the best.

Who Created It?

This part is a little confusing. Many older ads and reviews credit the program to Alex Larsson. The current official sales page, however, names Adam Kubinyi as the founder of Hyperbolic Stretching.

I could not find verified details about either name’s formal training or certifications. So I am judging the program on its methods and what is included, not on the creator’s résumé. That is a fair approach for any program where the background is unclear.

What’s Inside

According to the sales page at the time of writing, you get:

• 8-minute video routines for hamstrings, hip flexors and front splits
• Routines for lateral hip opening and side splits
• Forward fold, back bend and upper body flexibility routines
• Morning and evening bed flows, plus maintenance flows
• A PDF guide for combining routines
• Bonus: dynamic stretching and athletic warm-ups
• Bonus: wall-bar stretching
• Bonus: ongoing support
• Lifetime access to the online video portal

That is a broad library for one price. Having routines for different body areas makes it easy to target your personal tight spots instead of doing the same generic stretch session every day.

What the Science Supports (and What’s Hype)

The sales page talks about the stretch reflex and the inverse stretch reflex. These are real. When a muscle is stretched quickly, it reflexively tightens to protect itself. When a muscle is under strong tension, the nervous system can signal it to relax.

Using that relaxation response is the basis of contract-relax stretching, often called PNF stretching. You contract the muscle for a few seconds, relax, then ease deeper. Studies consistently show PNF and regular static stretching both improve range of motion when practiced regularly.

A big part of fast early gains is improved stretch tolerance. Your nervous system simply gets more comfortable with the position. That is real progress, and it is why many people feel looser within a couple of weeks.

Where the marketing gets ahead of itself is the timeline. Lines like “noticeable progress reported by many in just weeks” are fine. But the program’s wider advertising often implies full splits in a short window. For most adults, especially after 30, full splits take many months of steady practice, and some people’s hip structure may never allow them.

The other honest note: 8 minutes is enough to make progress, but only if you do it most days. Consistency beats intensity with flexibility training, every time.

Who It’s For (and Who Should Skip It)

Hyperbolic Stretching is a good fit for women who sit a lot, feel stiff in the hips and hamstrings, and want a simple daily routine. It also suits men. Lifters, runners and martial artists often have tight hips and can benefit from regular, structured stretching.

Skip it, or check with a professional first, if you are recovering from an injury, have hypermobility, or are pregnant. Hypermobile people usually need stability work more than extra stretching. And if you know you won’t stretch regularly, no program will help much.

Price, Guarantee and Upsells

At the time of writing, the sales page lists Hyperbolic Stretching at about $47, shown as a discount from $197. It is a one-time fee plus any sales tax or VAT, with no recurring charge.

Orders are processed by ClickBank, and the page offers a 60-day, no-questions-asked money-back guarantee. I did not see specific upsells on the main sales page, but ClickBank products often show extra offers after checkout. You can decline anything you don’t need.

Coach Luke’s Verdict

Underneath the flashy ads, Hyperbolic Stretching is built on sensible methods. Contract-relax stretching works, short daily sessions are realistic, and the routine library is broad for the price.

Just set realistic expectations. You will likely feel looser in a few weeks. Big milestones like full splits take much longer. If you go in with that mindset and actually show up most days, it is a reasonable investment.

My rating: 3.5/5

Frequently Asked Questions

The Bottom Line

Hyperbolic Stretching takes a proven stretching method and packages it into short, easy-to-follow videos. That is genuinely useful for busy people who struggle to stretch on their own.

Ignore the hype about overnight transformations, commit to a few minutes most days, and pair it with strength training. That is how you build flexibility that actually lasts.
