Working out is so hard...

I would do 2.

I would get rid of the belt. I think they are more of a cruch then anything else. then i would have just pushed through with a sloppy rep. I think one sloppy rep is just like getting a spot on a bench press. Another thing you could have done is dropped the weight take a 30 second rest then try the lift again.

Happy lifting

Depends how sloppy and how long you have been training. Many new people won't understand the difference between a cheat rep and a real rep.

That's exactly why you'd never catch me doing that stuff.

Next thing, your arms fall off.

I'll stick with cardio, thankyouverymuch.

I would
1. Nix the belt. Unless you already have a injury or competing at a level that maybe 1% can do then why have it? It's only a crutch to cover bad form until its too late and you hurt yourself.
2. Not take whey protein until after I'm done with my workout. Why take it right before? If you are pushing yourself then your digestion process is put on hold. There is no huge rush to get protein in there. Digestion doesn't happen that quickly so by that logic you should be taking it HOURS ahead of time.
3. Stop when your form gets sloppy. Locking out a really high weight is awesome. What is even more awesome is not having an impacted back that puts you out of the game for months.

Meh, I guess we all have our own broscience at the end of the day so just my 2 cents.

Depending on the lift, either 1 or 2. If it's a lift where injury is a concern (deads and OHP for me), then I'd stop when form got overly sloppy. If injury wasn't a concern, I'd push through it.

Off topic, what's up with all the votes for not wearing a belt? Wearing a belt during progression/max/new weight sets can be crucial for safety. Especially on deadlifts. That's like telling someone not to wear a seatbelt. Insane advice. Always wear a belt when maxing out, at least once your weights get up to a reasonably heavy level.

Because I trust a Dr and professor of spine biomechanics over a gymbro any day when it comes to my back health. Just my personal reason.

Here is his website: http://www.backfitpro.com/

Here one of his papers talking about it: http://www.backfitpro.com/pdf/weight_belts.pdf

Here is the TL:DR version for us ADD folks: http://stronglifts.com/weight-lifting-belts-to-wear-or-not-to-wear/

I like that your link for the summary is from SL. Yet in his videos, Mehdi is always wearing a belt on his maximal work. So I'm guessing he didn't see much value in that article either.

There's a billion sites listing the pros and cons of wearing belts:

http://articles.elitefts.com/training-articles/benefits-and-proper-use-of-weightlifting-belts/

The long and short of it is, if you watch any powerlifting competition, strongman competition, olympic lifts, etc you will see 99.9% of participants using a belt. If you see any truly strong person in the gym they will be wearing a belt on their maximal sets. Basically, nobody pushes maximum weight without a belt unless they are insane. Yes, wearing a belt all the time is not recommended but it's not what I recommended either.

You're welcome to do whatever you want, but suggesting potentially dangerous techniques is not welcome. For example, some people practice rounded back deadlifts, and some are even quite (amazingly) successful at it (KK). That doesn't mean that it's a bright suggestion for just about everyone out there.

You asked whats up with all the votes for not wearing a belt....so I answered with an article written by a spinal biomechanics expert reviewing real scientific studies.

I like that your link for the summary is from SL. Yet in his videos, Mehdi is always wearing a belt on his maximal work. So I'm guessing he didn't see much value in that article either.

-The article on SL links to quick overview of the conclusions. If Mehdi is hypocritical than that is Mehdi's problem. He is not the one who wrote the article nor has any bearing on the article other than providing a quick summary. Further, who is to say that Mehdi hasn't experienced a back injury prior and would benefit from a weight belt (also outlined in the full paper). It is also addressed that you can lift slightly more weight with a belt (in reference to Mehdi is always wearing a belt on his maximal work)

-You are correct. There are hundreds of opinion articles out there on the pros and cons of a weight belt.

The long and short of it is, if you watch any powerlifting competition, strongman competition, olympic lifts, etc you will see 99.9% of participants using a belt. If you see any truly strong person in the gym they will be wearing a belt on their maximal sets. Basically, nobody pushes maximum weight without a belt unless they are insane.

This is true. This is also addressed in the article.

You're welcome to do whatever you want, but suggesting potentially dangerous techniques is not welcome. For example, some people practice rounded back deadlifts, and some are even quite (amazingly) successful at it (KK). That doesn't mean that it's a bright suggestion for just about everyone out there.

You say it is potentially dangerous technique. A Dr and spinal biomechanics expert disagrees citing actual studies. I don't think it would be a bright suggestion to take the word of an anonymous MFP poster backed up by opinion over his study.

So yeah, I guess I will continue to do whatever I want. That includes just answering the question you asked. It might be good to read the full paper and not the tl:dr version to see if he addresses your concerns. You seem knowledgeable so might be worth a read for you.

Alex, I'll take what's behind door number 3.
