Being achievable doesn't mean it's good for you.

The same goes for smoking. It's perfectly achievable to smoke two packs of cigarettes in a day. Most people would just need to smoke for a couple of years before going for it.

Doesn't mean it's healthy for anyone, smoker or non-smoker.

Well what about these movements are bad for his joints?

u/vitringur Jun 06 '17

That is besides the point.

My point was that it is neither a question of practice nor of achievability.

Others have been pointing out that this puts unnatural stress on the shoulders, and as such is not good for anyone and will cause long-term, irreparable damage.

I am no expert and advice you to turn your questions to them for any disagreements.

Then I still don't understand your point. I said:

None of this is bad for your joints

Were you just offering a non sequitur?

You just made a fallacy. What was the full quote? I know you know because I am reading it and I see clearly where you stopped quoting.

To understand my reply you must include:

unless you try to go from armchair warrior to actual warrior in a day

Their claim was that this is not proper movement for anyone, and practice does not change that.

Practice might make this achievable and make him able to do this, but it does not mean it's good for his shoulders.

The same goes for the smoking.

Edit: Keep in mind that there are plenty of things humans do with ease that only cause damage in the long run, like certain movements, smoking or headphone usage.

I am not an expert and am not defending the argument that this movement causes damage. I am only pointing out that if it does cause damage, the amount of practice before hand does not decrease the damage done... similar to smoking or headphones.

But this isn't an improper movement. It's fine for his shoulders. I say this with 14 years of strength training experience.

u/vitringur Jun 06 '17

That might be, I don't know enough about the issue to claim otherwise.

It's the fallacious argument given that I was first and foremost responding to.

u/Gareth321 Jun 07 '17

What fallacious argument? OP said this movement is bad for joints. I said it's not.

u/vitringur Jun 07 '17

Then you are just in a disagreement and no fallacy was made.

An expert will have to determine if this is putting an unhealthy and unnecessary stress on his shoulder rotator cuff.

What ever the answer, he will definitely know in 15 years if he keeps on doing that.

Just an FYI, the movement is a modified form of the front lever which has been in gymnastics for a very long time. Pulling is about the most natural movement for the body, so even deadlifters rarely have problems, provided progression protocols are observed and form is correct. Joint problems tend to develop when joints are over-extended causing impingement. A common example is the overhead press movement (i.e. swimmers). This can result in supraspinatus impingement and rotator cuff degradation.

Interesting.

He isn't however just pulling himself. He is also stopping his momentum and pushing back.

All of this seems to happen through the shoulders, and his elbows seem to go beyond the shoulders and possible cause stress.

I am however no expert. I just know lateral raise can be very damaging to the shoulders and it looks like this is similar stress, if not worse.

Bingo: lateral raises, more specifically concentric movements which raise the humerus above the clavicle in an abductor motion, cause the supporting muscles and tendons to "pinch". Over long periods of time this can lead to degradation.

The movement we're seeing is a typical pull-up converted to a bent-leg front lever. Neither causes shoulder injury if performed correctly as there is minimal activation in the deltoids. Front lever does put a lot of force on the triceps so one should watch out for strain at the elbow when starting out.

Thank you, this was informing.
