Cardio After Lifting = Muscle Loss?

After seeing pics of people who switched from weigh machines to free weights, I thought to do the same. DH generally does free weights so I asked for his help. After roughly 40 min, he and his parents were done but I wanted to do some cardio to burn more calories. DH disagreed and said I would just burn off the muscle that i just built. I'm on the bike now burning calories.
That makes no sense to me. I understand long term weight lifting is good for burning more calories at rest but isn't cardio important as well? Should you not do cardio right after lifting? Or this a recent "muscle magazine" trend?

I don't know any rules, etc. on this, but I do heavy weights 3x week and do cardio 5 days a week. I'm definitely building muscle, can feel them and my inches are decreasing. My scale weight has stayed about the same though. In my head, I'm losing fat from cardio, gaining muscle from weights and I look and feel better so it's working for me. Now if that is actually what is happening in my body - I have no idea.0

When you do weight lifting as hard as you should, you won't have enough energy for a hardcore cardio session afterwards. A little bit of cardio, sure, but not as hard as you usually go.
It's generally not possible to build muscle and lose fat in the same session. Muscle building requires caloric surplus (eat more than you burn). Fat loss requires caloric deficit (eat less than you burn). The two of them are mutually exclusive. Super-new beginners may be exceptions, but you're not going to be super-new for long.
What *is* possible is to lose fat so that your existing muscles show better. You become tighter and gain more definition, and may even gain some strength... but not mass/size.0 -
if someone can do endurance style cardio after they lift then they arent lifting enough weights.
i regularly do cardio on he treadmill after my lifting sessions but 20 minutes is my MAX and i'm probably only to run about 5 minutes of that time.
i save my longer 45-60 minute cardio sessions for non lifting days0 -

QFT. I am a runner, but I schedule my real running and lifting on separate days. You can't get the max out of two activities back-to-back. I ran yesterday after lifting, but only at about 80% of my tempo run speed and only for 15 mins. If you're lifting using the principle of overload (which you should be) your muscle should be too fatigued to do endurance cardio.
That being said, you get maximum fat-burning from some cardio after lifting. Longer than around 30 minutes can be more catabolic then beneficial. A lower intensity shorter bit of cardio after lifting can be beneficial for meeting fat loss goals.0 -
The cardio after weights is basically to push your muscles a bit more and to flush them out,
its not true cardio because your hard weight training has burned you out,
your doing cardio type exercises but not true cardio,
and then there is a cool down.0 -

"Burn off the muscle you just built"? That sounds like 'bro science' to me... I'd ask him to show you where he read that. I do realize that if you were lifting to your full ability, you probably wouldn't have the *energy* to do serious cardio, but as far as it negating your efforts...well, I'm just a big doubting Thomas on that one. Seems like he might be one of those people who confuse fat with muscle.
Then again, maybe I'm completely wrong. :laugh:0 -
I wasn't doing high intensity cardio (a comfortable zone 2 according to my HRM).. I ended up being able to do about 30 min. We did upper body for lifting and my cardio was on the bike.
Earlier in the year, I was working out 5-6 days a week and I would do the weight machines M T TH F with cardio (for about an hour total workout time), W and a weekend day cardio only (appx. 1 hour). I really slimmed down and toned up. Didn't lose much weight for about 3 months (5 pounds and this was after a 35+ pound weight loss), but lost inches! Depression hit and everything went out the window so now i'm trying to get back into the swing of things.
Thanks for the replies!! Hearing what DH said really surprised me because just a few years ago he was telling me how cardio after lifting is what you should do. Tomorrow I will be sure to do an only cardio day and I will try to get back to what I used to do (except with free weights!).0 -
technically you don't build muscle when you lift. you build muscle the next day.0

but what if you lifted the day before?

You don't build muscle in the gym; you create microtears in the muscle fibers. You build muscle when you sleep as these microtears are repaired. Doing some cardoi after a strength workout is more or less fine if you have some leftover energy, though I prefer to split cardio and strength to different days.0

Nope. Not the case. At the level of lifting and cardio we're talking about here you'll be just fine. Go ahead, lift first and do your cardio after.0

Yeah, I'm not doing "heavy" lifting. I am pretty much a beginner at free weights and the different muscles that are needed are so not strong yet. I've also not been exercising on a regular schedule and only just started back up this month after a few months off.
I'm a noob. My ultimate goal to just get back on the horse (literally), so super heavy lifting may not ever be for me.0 -
Get your protein shake immediately after weight lifting then do your cardio.
Also keep your protein intake high every day, and you will never worry about muscle's loss.0 -
I have actually read several articles stating the opposite. Doing cardio after lifting people where shown to have increased level of HGH in the system leading to better strength and muscle gains. Also people where shown to lose more fat because the glycogen stores in your muscles have all been but depleted so your body will use the fat to burn. Of course the cardio was a moderate intensity for 30 mins at most I believe.0

Cardio doesn't kill gains, and unless you're eating a caloric surpless you won't be making any gains anyways, (besides, noob gains, maybe)
Do your cardio.0 -
I started doing cardio before lifting and loved it but then found that cardio after lifting gave a lot more energy for lifting. Normally I lift for about a hour and do some type of cardio 15-30 minutes after lifting... have not done anything but gain a lot of strength, no muscle loss that I am aware of and yes this is eating at a small deflict. PEOPLE WILL GIVE YOU A MILLION DIFFERENT ANSWERS .. DO WHAT WORKS FOR YOU ;-)0

This and that.
I lift 3 days a week and run 3 days a week. On different days.
After lifting, about the only thing I can do is sit down and log my exercise. :laugh:0 -
Nothing wrong with doing both cardio and weight lifting at the same time. I have a friend who's constantly gaining muscle with a low body fat range. If i had to guess, he has around 8% body fat. He does 50 minutes of cardio with a goal of hitting 6 miles in those 50 mins and then he lifts weights. He spends 3 to 4 days in the gym at 2 hours a day. He also drinks a protein shake during his workout so this probably prevents any muscle loss that you might be afraid of.

Link below to a summary of real scientific research that shows doing both cardio and strength training in the same day does not matter.
http://www.muscleandfitness.com/training/other/should-you-do-weight-training-cardio-same-dayHowever, the results of the studies actually showed that performing weight training and cardio on the same day had no negative effects on endurance training, resistance training, or muscle growth. In fact, they found that doing 50 percent less of both types of exercise on the same day produced the same results as doing full workouts devoted to one or the other. So, if you’ve been doing your weight training and cardio on separate days, combine your workout to get more bang for your buck.
Edit: There is a simple and logical explanation as to why muscle gains were not stunted in the study above. It's because cardio increases heart rate which in turn increases blood flow to your muscles, which in turn increases muscle repair process by providing more nutrients to the muscles that require any repairs.

With science aside. I found a better answer in the link below. Doing cardio and Weight training in the same day matters only to YOU and what your energy levels are capable off.

The body always uses a combination of fuel substrates during exercise. The percentage is determined primarily by intensity. However, the mix of fuel substrates used during cardio has zero effect--zip, nada, no mas--on stored body fat.0 -

its not true cardio because your hard weight training has burned you out,

Flush what out? Even at rest, your body circulates its entire blood supply every 25 seconds or so.0 -
No it won't equal muscle loss. I did the most intense cardiovascular session I've ever done before of heavy lifting, I get so buzzed and pumped up after lifting it gives me the extra energy to go the extra mile!0

That's sounds bogus to me. If u run a full marathon every day, of course you'll canabalize some muscle. Your body has to get fuel from somewhere but 20 - 30 mins of cardio isn't going to do that in my opinion. I do cardio nearly every day after lifting and my strength and stamina is steadily increasing so I'm sure I'm not loosing muscle from it.0

I left with weights and then right after, I will do cardio with cross trainer, and I love it because it stretches out my muscles. I dont want to be stiff, and then after my half and hour of cardio, I will lift another part of the body,and then another half and hour of cardio.
usually after the cardio, I can lift a little heavier because my muscles are so warmed up.0 -

You do not need to get your protein shake immediately after weight lifting. The absorption window for protein is about 24 hours. You just need to get your protein in for the day and you will be good.0 -
i dont think you have to worry about muscle loss youre not training to compete on a bodybuilding stage right? so enjoy your cardio btw protein shake should be consume within 30 minutes after your workout to help rebuild muscle0

After weight lifting your muscles reach maximum need and want to start repairing muscle tissues " small tears" and you should take something that is easy ingestion " such as protein shake " to supply it with the needs.0 -

There is new research that suggests that might not be the case and the comment about the "24 hour window" may be more accurate.0
