Is HIIT undoing all my hard work on the gym floor?

I've recently read that intense cardio such as HIIT can be bad for those hard earned gains from lifting weights...any thoughts?

I've actually always heard the opposite, that steady-state cardio is what can lead to muscle degradation but HIIT is fine. I find that I see the best gains and fat loss when I combine lifting with HIIT.
That being said, there's nothing that's really going to "undo" your lifting (except maybe not eating enough, causing your body to fuel itself with muscle). I've seen strength gains over the past 6 months even though I've been training for a marathon that whole time. If you're consistent with your weights, some cardio isn't going to ruin anything.0 -
It can definitely impact your recovery if that's a concern, but "undoing" work...no.0

Was this information in a peer-reviewed scientific journal which was discussing research,
or was it from a website run by who knows who & commented on by who knows who?
I'm betting on the latter.
No, cardio won't "undo" any gains from lifting weight,
unless you're overdoing it & not eating enough (as Lauren said).
But maybe if you're doing a lot of cardio (which generally uses leg muscles), go a little lighter on the strength
work on legs the days surrounding the cardio, so they have time to rebuild the muscle (which is when it gets
stronger; that's why rest days are important).1 -
Thanks guys....I've had great results combing both so when I read that I was slightly baffled, the person was highly qualified so it made me think. At the same time though I'm a big believer in doing whatever works for u, and combining both certainly works for me0

"Walking or cycling at a low to moderate intensity burns off some extra fat without interfering too much with your performance in the gym. That’s not the case with more intense forms of exercise, such as HIIT."

That goes back to what Dope said. The issue is recovery, not the it undoes your work, but that it could hinder your progress.0 -
Wouldn't it be great if muscles were that responsive? Like Alice in wonderland?

He is likely referencing a day/or over generalizing the results of a single study. Need a constant supply of shiny objects....0

^ Recovery is indeed the point. If somebody is truly doing HIIT (and not just aerobic intervals), the HIIT is very taxing to the CNS and creates recovery issues of its own separate from the recovery issues associated with strength training. The most sensible recommendation I've seen is to perform HIIT no more than twice a week, with low/moderate intensity cardio on other days.
A separate issue is that what most people consider HIIT is not actually HIIT. It's become a trendy acronym in the fitness world, but it's grossly misused. Walk/jog intervals aren't HIIT - it requires absolute maximal, all-out effort during the work periods. Not many people actually do true HIIT workouts because they're very uncomfortable/painful and most people don't enjoy lying on the ground gasping for breath and trying not to throw up on themselves at the end of a workout.0 -

Yup, seems to be about recovery - you really do need to let muscles rest and recover. I do HIIT immediately after the resistance training, then have a rest day the following day consisting only of light exercise like walking (which for my level of fitness isn't a challenge). You might experience overtraining if you did strength training, HIIT with the same muscles the next day, and then strength training again.0 -

Yeah I'm not sure how I feel about this. Isn't the whole thing made up to begin with? Was there some definition included with the development and packaging of this form of exercise that said only certain things could be HIIT? How does the fitness world misuse something it basically invented?0 -

1) Because it's trendy and if they call it "HIIT", they can get people to sign up for their workout classes (money!).
2) Because they can make up their own protocols, call it "HIIT" and sell books, DVDs, programs, etc. (money!).
The definition of HIIT is short periods of maximal intensity exercise interspersed with less intense recovery periods. There are many different protocols used (Tabata being probably the most well-known) - but basically if you're not doing maximal intensity during the work periods, it's not HIIT. It may be interval training, but it's not High Intensity Interval Training (which is what the acronym stands for).
While there may be no specific protocol, any form of actual HIIT is going to be very uncomfortable. More uncomfortable than most people will tolerate, and certainly brutal for a beginner with limited/no aerobic capacity (not to mention the possibility of injury from going all-out with a body that's not conditioned for that type of effort).0 -

My understanding was that HIIT is description for protocols used in scientific studies (though it originated long before that in athletes). When those studies started showing the benefits of HIIT, it became a vague marketing term for the fitness industry to sell you on those same benefits. I agree with the others, real HIIT is alternating intervals of maximal effort with recovery. I'd go one step further and say that the recovery should be passive if your really want to imitate the protocol in most studies.0 -

Interesting! If there are actual studies indicating that it must be high intensity to the death training to be considered HIIT, I'd be curious to see those. Otherwise IMO it's just opinion on top of opinion. Meaning, who cares, so long as people are working out at their own definition of high intensity, what's it hurting, and yes they're getting some benefit. However, again, if there are specific scientific studies delineating absolute maximum effort as a requirement to be HIIT, and associated benefits that do not exist unless you're going full pelt, I'm definitely curious. Otherwise it does seem like ascribing scientific definitions to, yep, a marketing term0 -

The positive effects of HIIT seen in research are using High Intensity protocols (90%+ VOmax) -- if you think your suboptimal 10 minute pseudo HIIT is going to be equal to an hour of running then it hurts because these are basically useless for either cardiovascular health or calorie burns. So when people come out with "yeah, I tried it. Didn't work" they hurt themselves and are getting no benefit.
It's a research definition first then became a marketing term.1 -
