Need your feedback: 1/4″ finger length increase and new clamping device is key to leg growth

Here’s the before progress with the initial pic of the finger.  Here’s the last pic of the finger


You can see a comparison of the left and right fingers and see that the right finger is longer than the left finger and much thicker.

Here’s a side to side comparison of the left and right fingers:


You’ll notice that the right finger is longer than the left finger and not that the right knuckle is higher than the left knuckle so there’s no measurement shennanigans.  Is this pic enough to push as proof that LSJL finger growth is a success?  Let me know if you’d suggest any adjustments.

Here’s another image:


Both the right finger is longer than the left finger at the tip and the right knucle is higher than the left knuckle.  Nails on the bother inner most fingers are trimmed.

Here’s some pictures of my right hand from four years ago.  Note that the method is obsolete but you can see a finger length increase between then and today.

Here’s a video with the right hand as well:

I found this video about performing LSJL:

This individual got results after 20 days which is likely due to the superior clamping device.   And is more in line with the finger results I’ve gotten.  I’ve gained about a 1/4 of inch in finger length and a drastic increase in finger width.  Comparing the thumb pics it looks like there may be some length gain there but the thumb is farther along the ruler in the before pic but a side to side comparison of right to left thumb reveals that a possible increase of 1/8th of an inch or so.

So it’s been about 1 3/4 year loading my finger and I’ve gained say 1/4″.  Since my finger is around 3 1/2″ long that’s about a 7% increase.  Now a 7% increase in the tibia bone of say 16 inches would be 17.02 inches which would be a full inch of height.  Now other than the initial gain in height at the beginning I have not gained significantly over time.

Now the key thing is despite my initial gain I’m not gaining length as rapidly in the legs as in the fingers and I’m not getting the drastic increase in width in the legs as in the fingers.  This could be due to physiological differences between the leg and finger bones.  The finger bones do not have periosteum for example or it could be due to the existing clamping device not being sufficient enough load.  The load I’ve been using for 500 counts on the finger is quite extreme relative load.

I’ve been tweaking the load of the legs.  Changing clamp position and bending the knee while loading the knee to get more leverage but we need to find a way to get the same kind of loads that can be done with the finger.

Importantly, we have finger proof.  Longer fingers could be valuable to piano players and guitar players and possibly some other athletes.  So how can we use this finger technique to raise funds to develop a more effective leg clamping device.  I think we can go even further than this gentleman here in developing a better clamping device.


What kind of evidence and documentation do I need to present to the layperson to show the finger proof of concept to generate interest and funding in developing a leg loading device?

    Do you have a before pic of your left index finger? Your right finger doesn’t look any longer than before. Also, your pictures still suck.

      1. Rickers

        The difference between my right and left index fingers is similar to the difference between yours.

        1. Tyler Post author

          yeah but mine wasn’t like that before. It’s hard to do an exact comparison unless I chop the fingers off. Let me know if the newest pic I put up is more convincing. Can you post a pic comparing your right and left index finger? Does your right finger have the dramatic increase in thickness and the enhanced epiphysis?

          1. Rickers

            Sorry but I’m not convinced. Did you compare measurements before or just assume they were the same? One hand is often larger than the other, same with feet. Regarding proof, I agree with Marcos. You need before and after x-rays.

            Well none of my other fingers are longer than the other hand fingers or at least very minorly a few mm’s. I can do LSJL on any of my fingers or toes and I’d estimate visible results. There’s already visible results with my left thumb which I’ve been loading for about a month. I can post those but the difference is very minor.

            I can do LSJL on my left hand so the two fingers can become more equal. The cost of getting x-rays out of pocket is too much.

    I don’t reach to see any length difference between your fingers…1/4 inch is something that should be easy to notice. Could you provide more picks?

  3. Guranc


    But the difference does not look like 1/4″ (such a length should make a BIG difference for a finger)
    Your left nails are longer than your right nails, so… pretty hard to see.

    I think that you would get a lot more credibility if you took better quality photos.
    Come on man! You are doing some insane work, but you kinda “ruin” it by posting bad pics.
    Get some decent camera, it’s very affordable today and should increase the value of your results.

    I believe in you Tyler. But for a proof to be a proof, it has to be very solid, I think.

    So… I don’t know, align your fingers on a sheet with graduations on it, or something! That would be perfect.

      Well. I’ll clip my nails. But the reason it does not look like a 1/4″ is because it is about a quarter, the finger is curved, and the right finger is higher up than the left finger. You can see that the knuckle is higher than the left finger.

      We need to build a better clamp for legs and that’s going to take funding. Finger proof could get us finding. So I need proof enough that we can start getting the funds we need for a superior leg clamping device.

      So I’ll try another pic with clipped nails and against some sort of backdrop that gives a measurement reference. I need a pic that will inspire confidence in the layman that longitudinal bone growth is possible so we can get encouragement for other endeavors like building a stronger clamp.

        “against some sort of backdrop that gives a measurement reference. I need a pic that will inspire confidence in the layman that longitudinal bone growth is possible”

        Yes, I think that that’s exactly what you need! You really plan to get your project funded?

        You are too kind responding to everyone so calmly. Thanks.

    Tyler, why don’t you lay your hands palms down flat on a table….overlap one thumb on top of the other hand so you can line up the index fingers right next to each other…then take an overhead photo of your hand.

    I agree with the other commentator that stated that you tend to take very bad photos that negate what you are trying to provide proof of. Its not the quality of your camera necessarily but the camera angles and, in this instance, the position of your hand/fingers.

    Also, is the tip of your “longer” finger more pointed looking? If so, is that the result of the lsjl?

    1. Tyler Post author

      The reason that I take pictures where my finger is bent is that makes it easier to see where the finger starts. Also, taking a picture as you describe would require the assistance of another person. Doing it the way I did it you can use the knuckle as the basis for the way the finger starts. And since the right knuckle is above the left knuckle the finger length isn’t due to me sliding the finger down against the other.

      And yes, the pointed finger is due to the LSJL. I have not had problems with the finger strength or pain since doing LSJL.

      The pointed finger alone is proof that LSJL alters bone in addition to the increase in thickness and much more pronounced epiphysis.

      1. Guranc

        ” Also, taking a picture as you describe would require the assistance of another person.”

        No, not necessarily!
        You can put your camera normally on some horizontal support (a table, …) an set a 10-15sec delay for the photo.
        The camera will be pointing towards some vertical surface (a wall, a standing book, …) on which you can put your hands.

        You could also put your hands “palm against palm” and take a side view of them. Your index fingers will be very easy to compare this way (since they will touch each other).

        1. Tyler Post author

          Putting my fingers palm against palm makes it very easy to subtly slide the fingers making one finger appear longer than the other. On the other hand, there’s no way to manipulate where the finger bends.

    Why don’t you take x-rays of both hands and measure them using a caliper?
    Thats most accurate if you want to proof to potential investors…

    Hey Tyler,

    Although its v.little but I can clearly see the difference. But for me it pretty much proves the theory of LSJL.

    Honestly, i didn’t see any results for myself. may b i hv nt been doin it right but your efforts, consistency and result are significant.

    I’m ready to put in my money. Just say how much and when.

    Cheers !!!

    Hi Tyler,

    I just read your last post called “LSJL knee method + Progress update Part I”, where the pics you uploaded show a quite clear length difference between right and left hands. Thank you very much for your effort.
    In order to apply a more scientific method that would engage more people and also investors, have you thought on taking x-rays of your fingers? A good process would be to take a before X-ray of both hands, then apply the LSJL to one finger and take an after X-ray to both hands. By accurately measuring X-rays you have the definite prove that your method works.

    X-rays give you a very simple and objective way of proving you have elongated a finger.
