The problem (apparently) isn't the amount of reps you're doing, but rather the form (or type of exercise) that allows you to complete the motion when your fatigued muscles wouldn't otherwise let you.
Like the kipping pull ups, normally, if you can't complete a regular pull up after a certain amount of reps... you just can't do it and stop (right?). But by kipping you're still completing the motion even after fatigue. Or with GHD (?) situps, people will use their arms to complete the motion, but the muscles are still being activated even after total fatigue.
That's what I read in that thread at one point, anyway.

I'm with you...still stirs up irrational fears and wondering "What if my trainer is as stupid as all these Crossfit trainers? Will I know it?"

That sounds like someone attempting to push blame from the programming onto the execution, which IMO isn't fair. While cheating/kipping to complete reps may have an impact in some cases, you can cause excessive muscle breakdown using perfect form and retarded programming too.

I definitely don't disagree. Doing 100 pull ups, with 100 ghd sit ups, and then 100 push ups is definitely excessive.
Then again, I can't complete A pull up, but I probably could if I swung up.
That HQ hasn't addressed the problems these routines cause is definitely glaring.

Full disclosure, though, I didn't even know what crossfit consisted of until very recently and only really know what I know from the cathletics thread.

I disagree with 100 pull/push/sit being excessive. Seems to me that bodyweight stuff like that is programmable such that that a set like that is reasonable for an elite endurance athlete. Little easy push/sit wise tho. It's the reps on those lifts that scare me.

It's not the reps on the lifts that are leading to rhabdo, though. It's the pull ups and ghd sit ups.

I'mma shuddap though cause I'm out of my depth on this and don't like talking out my ass.

210 reps of 135 squats seems alot more stupid than 100 pullups. Especially if you're fit enough to do 100 pullups. My training eventually calls for 200push/200sit/75pull 4days a week along w/ lifting. Never heard of a trainee getting rhabdo. Pullups seem like a very good progression exercise given good form and proper strength. I just disagree that pullups at that magnitude if in proper shape with good form are dangerous. They're dangerous bc of the retard kippers and people who do GHDs with awful form and **** up their backs. Seems like 210 reps of any lift like a squat doesn't have utility though? Maybe I'm biased, dno.

210rep of squats at 135# is the stuff that causes rhabdo.

The hundreds of reps involving the shoulders lead to SLAP tears and sometimes when combined with other stuff Rhabdo.

Just going off what's posted in the cathletics thread where they're saying it's the 100 pull ups and ghd sits

These are some of the posts I was basing my statements off of. I don't doubt other exercises can induce exercise rhabdo, though.
Also seems like a big factor is when someone takes time off (as a conditioned athlete) and then jumps right back into where they were previously.

You're right, it can affect any muscle.

There is a difference in how the body responds to pushups/pullups/situps (and all exercises for that matter) when volume is gradually built up over time versus one huge increase in volume. It is not the volume of work in a vacuum that is the problem; it's the volume of work given the trainee's recent training history. I'm sure Burke will be able to handle the 200push/200sit/75pull soon if he can't already, but 100 pushups alone is probably more than it is appropriate to expect a pure novice to complete in a workout.

It is the responsibility of whoever is writing the programming to adapt the volume to appropriate levels for each trainee. This is part of where crossfit fails. Glassman is a huge proponent of scaling weights, but not reps. In some workouts this strategy can work (like grace or any of the barbell heavy workouts), but what do you do when it's an unscalable exercise like a GHD or a pullup? The novice trainee ends up doing way more work than is appropriate.

Just to throw one more stick onto the what type of exercises cause rhabdo debate fire, the eccentric component of exercises tend to lead to much more muscular breakdown than the concentric component. That's why huge bodybuilders train with a lot of forced reps and heavy negatives. In an exercise like a GHD there is a long eccentric component where you cannot relax or else you risk serious lumbar hyperextension. Compare this with a snatch where the weight is dropped from the top which has 0 eccentric component. I'm not saying that a long and controlled eccentric component is necessary to cause rhabdo, but it certainly contributes more than a purely concentric exercise would.

Honestly too many to list here but just as an example... my last 3 days with crossfit.
I'll just give you the legs portion of the WOD's.

Mon- front squat 1-10-1-20-1-30
Tues- 150 wall balls w/20#...150 24' box jumps
Wed- for time- 12-9-6 Deadlifts w/315#

Now I'm no programming expert and this might not even be bad, but I can't imagine this being a optimal line.
I could give you even worse examples for shoulders.

Opinion on Crossfit:

nearly everybody I see do it is really ****ing annoying, not strong, and seems to think what they are doing is the best/most important thing in the world. I have noticed a good amount of people that do it at my gym seem to have add/adhd. idk if that's because they can't focus on one ****ing set of squats at a time or what. I think they do crossfit for what I would call the desire to be in "beast mode". When you are moving light weights fast and for a lot of reps and moving on to the next thing, you feel like a beast, like your training is really hard but that you are crushing it.

Lol. I like how it's a timed workout broken into 3 rounds despite there only being 1 exercise.

Maybe if they had just written "27 reps for time at 315#" they would've realized how retarded it is.
