How do i make sure it doesn't go no contact on me? srs

Can i just lift high reps forever and be ok?

I believe the risk of cartilage wear actually increases more significantly with two factors: Volume and Poor Form.

Lifting heavy but with excellent form (from a biomechanical standpoint,notfrom a maximize-hypertrophy standpoint) is likely going to keep your joints healthiest the longest.

First thing is you have to understand what cartilage is. It's basically a lubricating pad around a joint surface to prevent the actual bone surface from being worn down and destroyed. It's basically a shock absorber for things like your hips and knees. So if you lift heavy constantly and don't take care of yourself, eventually it will wear down faster.

If you lift 200 pounds 10 times or 50 pounds 40 times, the overall load is the same. High reps low weight doesn't make a difference. What does is allowing the body to adapt properly to the load you're using and making sure that you don't overstress the joints.

Most lifters don't realize that you don't have to lift to failure to improve your strength.

I hear a lot of people in their 50s and 60s that lift say their shoulder cartilage is rekt and they even do weightless shoulder presses any more, how exactly could their form deviate to something that destroys their cartilage with such a simple straight line movement?

Cartilage is circular around a joint - so if you follow the same direction of force all the time, it will get worn down in that line. Kind of like a tire will wear down faster on one side if you only do right hand turns. That's one reason why changing direction of load is important to keep joints healthy. So for example, if you're doing an overhead press do it with varying elbow angles so your shoulder is abducted at 30, 60 or 90 degrees. Same load on the muscle, different angle through the joint.

They likely went through an incredible amount of volume (especially now being 50-60+ years old) doing repetitive shoulder movements over and over and over and over and over and over. Same exact thing happens to labormen, dudes in factories and on assembly lines, tradies, etc. They all get 'ergonomics' training, but when it comes down to it if you do 30 years of 'pick up the 1.5lb part, lift it to 6 inches above head height, move 1 foot through the sagittal plane, and do two counter-clockwise twists' about 900 times in a day, your shoulder is not going to be happy. Add in minute form dysfunctions because even 1.5lbs becomes incredibly heavy after you move it enough times, and now the lovely lubricating tissues and connective tissues start getting upset.

If you've never heard of someone wrecking their back doing a simple hip-hinge (one of the most basic movements our bodies are designed to do (DL)), wrecking their knees doing a simple squat (one of the absolute most functional movements that literal 2 year olds instinctively do correctly), wrecking their elbows playing high-frequency swinging sports (tennis rackets weigh less than .75 lb....), wrecking their {insert literally anything here because someone did something thatshouldbe easy and honestly good for your body and joints, but did it incorrectly to a significant degree or mildly incorrect over a vast amount of volume] then you might need to start asking more questions.

Bodybuilding isnota joint friendly venture because so much emphasis nowadays is put on machines that limit motion to one specific line or curve that may not actually fit everyone's anatomy. It focuses on the 'show muscles' to such a degree that joint and motion dysfunction is rampant. 'Frozen joints' are as common in "bodybuilders" (usually not most knowledgeable pros, but more the amateur crowd..) as they are in desk-sitters, gamers, etc. 'Posture' for most "bodybuilders" isn't even a word they recognize. When you combine all of these factors, things like cartilage get hit the hardest because the person says "**** it I want to do OHP even though my thoracic extension is chit because I've done so much bench pressing with garbage form while simultaneously neglecting my rear delts and any form of rotator cuff functional training. So I'll hop on a seated machine OHP that forces my shoulder to move in ONE singular motion and just ignore that slightly nagging feeling I get when I do my 20 reps (because lighter weights are better bro) and get massive delts bro.

And then you look at how those dudes who are now 50, 60, 70 years old have been training in a similar fashion for a long time but starting out at a point ofeven lesstraining knowledge (what is available now in terms of knowledge is vastly greater than what was available 40 years ago) than what we have now and it actually should be no surprise that they have joints that are fukking wrecked.

And to be clear, an OHP isnota 'simply straight line movement' if you actually look at what all goes into ensuring a stable base, core, spinal alignment, scapular control, flexion and rotation at the shoulder.... add it all up and ifsomethingis going to go wrong, it will likely be at the joint with the most movement - the shoulder itself. Do it 20000 times over 30 years and yeah, cartilage is fukked.

ffs i just wanted to do the same 6 movements of exercise till i dieded

If your avi is really you, you likely have a good amount of training knowledge, and more importantly know how toapplythat knowledge.

Do a bit of research on "functional movement" (NOT CROSSFIT "FUNCTIONAL" - all caps for emphasis. fukk those crossfit fukkers using the word 'functional' to promote their BS) and incorporate a bit of that into your training where you see some points you could improve, and honestly you could probably do the same 6 movements forever lol.

Glucosamine Sulphate & Chondroitin appear to help…i dont have cartilage issues so idk for sure…good form is best prevention but I imagine with repetition and heavy weights its likely to happen

Humans are meant to be 16-18 bmi and live till 28 and then die.

You never lift high reps, so you don't know.

nobody does 50 for 40 in place of 200 for 10. It is more like 175 pounds for 20 in place of 200 for 10. That is the beauty of high reps. You can safely exhaust muscle (go to failure in your terms) without injury. I am 56, and this is the way to lift. My joints are better than they were at my 35.

Speaking of cartilage weardown, we should probably think of how it growth in first place. There is no blood vessels feeding nutrients to cartilage, it is fed by movement alone. Not movement while you lift, but movement of a joint during other 23 hours of your day.

Your math is a bit off, and I was talking about total load over the set on the joint. 175x20 is 3500 pounds of total resistance and 20x10 is 2000. There's a bunch of other factors in play as to whether or not you complete the set and how much fatigue takes place ie speed of reps, length of limbs, etc. Many powerlifters for example use a total load strategy when it comes to workouts and their volume.

Whatever works for you rep wise is great, OP wanted to know about cartilage and why it wears down.

Bumping this, but as a dude with suspected cartilage issues in the knee from who knows what (I would lift/run/walk/stretch properly & regularly), I'll be trying out the glucosamine/Chondroitin/MSM stack & report back.
