Fatsed Cardio vs PWO Cardio - thinking of changing routine to maximize lifts

[MACKATTACK]

I am thinking of changing my cardio routine to maximize my lifts......

I usually do fasted HIIT in the mornings first thing but I notice less energy in the afternoons during my lifts, as suppose when I dont do any cardio and then lift afternoons...



So I am looking do 45 mins of cardio PWO, some fast paced with HIIT mixed in.

Is 45 minutes too much PWO?

Do you think PWO cardio will be as effective as morning fasted cardio considering PWO I am in the fat burning zone to begin with??

[austinite]

45 minutes PWO is not too much at all. It's perfect.

Yes, it's just as effective as fasted. The time of day you do cardio is not relevant whatsoever.

Perfect I am going to make the change tomorrow. Now I can get more sleep too!!! Yyyaaayyyyy lol

[CMB]

I do 45 minutes everytime I do cardio, and it is perfect I agree.

Why would anybody do fasted cardio I have no idea...If you're not on cycle while doing fasted cardio you'll lose muscle mass. period. there is no argument here.

Well there is an argument here.....

My argument would be that your claim is false and based on nothing.....

Explain how if the primary source of fuel for LISS cardio is fatty acids we will be burning Muscle if we do cardio fasted.....

If I was eating 10,000 calories a day would I still be burning LBM if I was doing cardio fasted.....


We need to look at the bigger picture when it comes to cardio..... Too many people over think the whole thing....

[M302_Imola]

I wouldn't totally get away from doing morning fasted cardio, instead I would use a mixed approach...some days morn fasted cardio and some days pwo cardio. IMO, pwo cardio with a duration of 45 mins isn't a problem if one is doing LISS (low intensity steady state), however I wouldn't start throwing HIIT cardio into the equation when muscle glycogen levels are depleted. You're setting yourself up to burn some muscle IMO. LISS is perfect in the glycogen depleted state but with HIIT I like to have some glycogen in the system. Anyhow, take it for what's its worth but this is what works for me and most the people I train.

^This^

If you want to do HIIT after workout I would suggest no more than 20 mins MAX! Otherwise you will likely be burning muscle. For optimum results switch it up.. 15-20 mins HIIT for a week PWO. Then 30-45 mins steady state fat burning range for a week. Fasted cardio is a great way to go also as long as you stay at fat burning range or slightly above and don't exceed 30-45 mins. Always do cardio when glycogen levels are depleted for best results. ie PWO or first thing in the morning.

Hey everyone, lets go run around at 6am like a bunch of starving zombies. good idea right?

[M302_Imola]

This thread lasted longer than I thought . There is no evidence that what's in your stomach and/or what time you cardio has lesser or greater effect on fat loss. I'd love to see any studies.

This is always a heated topic. Not to sound like an arrogant ass, but honestly I don't need to see the studies...proof is in the pudding! I know what has worked for me in terms of getting lean while holding onto muscle tissue (aas free, I like to cut naturally and then use aas to build lean muscle tissue at that point).

I love how just because some members here have thousands of posts means they MUST be correct.

Your argument is that if I wake up after 8 hours of sleep and no food, and go for a 45 minutes run, I won't lose an ounce of muscle.

bull$#it.

I don't really need to say anything here as you've done a pretty good job at making yourself look foolish. I've got an idea, quit hiding behind the racktastic chick in your avy pic and post up some pics of yourself!

Lastly, I know there are MANY variables when it comes to losing muscle. Too many to count. However, when you burn calories, without consuming calories beforehand, then you will go into a CATABOLIC mode. For those couple vets who shot down my statement as false, google catabolic and the definition. It goes hand in hand with fasted cardio.

Not trying to flame here, but everyone has their own opinion. We can't know certainly who is right but we can make educated guesses from experience and sports medicine.

A few last words: Fitness is NOT an exact science. So keep that in mind next time you say something is completely false.

Ok I will keep that in mind but your statement is still completely false.

You need to read up on the difference between blood glucose levels and stored glycogen. How much glycogen do you think is stored in muscle tissue and the liver? Do you really think someone eating a "normal" type diet can deplete their glucose levels during 8 hours of sleep which slows metabolism to nearly zilch?

Your view of how the body processes and partitions calories/nutrients is narrow minded at best.

My post count is much lower than the 2 other vets so I'm sure that makes me more credible.

Lol post count means nothing.

We cannot answer this question without knowing the detail..... It's not black and white......

Stats?
Intensity?
Level of glycogen stored?

And most importantly overall calorie intake.....

Lastly, I know there are MANY variables when it comes to losing muscle. Too many to count. However, when you burn calories, without consuming calories beforehand, then you will go into a CATABOLIC modelol this is ironic.... Are you aware that the process of freeing fatty acids from adipose tissue (fat mobilisation) is a CATABOLIC process....ie. if your cardio wasn't considered catabolic then that would mean you released no fatty acids to burn during it..... This is kind of beyond the point but a point worth making..... For those couple vets who shot down my statement as false, google catabolic and the definition. It goes hand in hand with fasted cardio.I am fully aware of the term catabolic and I think you need to understand that we cannot gauge the effects of a cardio session based on on what occurs during that cardio session (hence me saying 'see the bigger picture')......

With your last statement you really show your colours.... You were the one who made a bold and extreme statement..... And even closed it with 'There is no argument here'.....

I'm not being a Cvnt to anyone here.... Any time I challenge sum1 I'm not picking on them..... The issues stem form the bent fitness industry and we are all or have all been suckers at one point, playing into there hands....


When I see things that I know (or even think) are wrong I will challenge it..... And I tend to not challenge many topics but this is one I will have a good go at.....

As it should bro! Keep it up!

[oatmeal69]

I was doing fasted cardio for a long time. I'm starting to think more along the lines of what austinite says. It doesn't matter when you do it, or if it's fasted or not. It's about how many calories you take in, vs. what you burn off each day, period.
The last 6 months I've been doing 30 min interval cardio, PWO. I'm on cycle now and seem to be leaning up even while adding mass.

When doing LISS cardio it most certainly does matter when you perform it, if fatloss (while sparring muscle tissue) is the main goal. You're body needs to be glycogen depleted to receive the maximum benefit (fatloss). Look at it this way, time is money...so why would you waste your time performing LISS when glycogen levels are full or partially full? If you're like me you never have enough time in the day so this is a simple decision for me.

Well, by that token, would you say that glycogen levels are depleted PWO? Or do you think there's more bang for buck after sleeping 8 hours, etc.?

Glycogen levels get depleted after a workout. How much depends on intensity and duration. None the less they are depleted to a point where cardio is MUCH more beneficial. The reason is because now your body must rely on adipose tissue (fat) for its energy. Thus burning fat. Yes the morning is the most beneficial time to do cardio. Your body will burn 300% more fat this way. Why burn off food that you ate when you can burn off stored fat in your body?? No-brainer to me.

I hear you, everything you say makes sense. I've found though as a skinny-fat lil' runt, I can only diet/cardio so much before my genes take over an cause me to lose muscle and keep fat. I've been talking with GBrice about it a lot lately, I'm starting to think that for guys like me, we just have to keep eating and make up for it with lots of cardio. - Keep the furnace stoked and burning white-hot. Otherwise we get into the catabolic state much more easily than others.
P.S., great arms/shoulders man, I hope to have half of that someday!

Yet another case of missing the bigger picture.....

To many false statements and assumptions in this reply to even begin.....


I reccomended you research metabolism as a whole rather than just the acute effects of a cardio session that is burning fatty acids....

[cj111]

I've done both.
I like the feeling after fasted cardio in the morning, like you're ready for the day! Its a weird feeling...
I also like doing 40 min PWO,

Bottom line who cares when you do it, as long as you're making the effort to consistantly do something!
As far as burning muscle while doing cardio fasted, never happened to me. I believe the whole catabolism thing is really over played

I like what you did there with the word "token" since my post referred to time being money...nicely done Live for the PUMP had a nice reply to your question. Whether glycogen levels are lower when you wake up in the morn (after 8 hrs. sleep) or after an intense workout (intensity will vary) is a good question but I'm not sure we can answer it. I would dare to say glycogen levels are lower in the morn upon waking since the body has been at idle for 8 hrs. and blood glucose levels should also be the lowest at this time. None-the-less both fasted cardio and pwo cardio are beneficial from a fatloss standpoint. If I had to choose (and my work schedule didn't interfere then I would choose fasted morn cardio.

You're correct in that there are a lot of different body types so what works for one might not work for another. Do you use peptides (GHRP/GHRH)? If not, you should be! They are exceptionally good at helping you stay anti catabolic during cardio and at other points in the day...not to mention they essentially speed up your metabolism where you can feed the muscle tissue more nutrients while staying just as lean if not leaner. Example, my maintenance cals use to be right around 3000 when I was around 195 @12% bf...since I've been on peps I've raised my maintenance cals to between 3300-3500 while now weighing 200 lbs. @ 10% bf. Now granted my fatloss strategy and training has been enhanced by me gaining knowledge in this area and also knowing my body. GHRP/GHRH can be a big help at helping shed fat (while staying anti catabolic) when pinned before fasted morn cardio or pwo cardio. Here's my typical plan before fasted cardio: wake up and pin peps at 4:30 am then roll over and go back to bed until 5:30am, then I get ready and head to the treadmill at the gym, I do 30-40 mins LISS cardio (HR around 130 BPM), which is normally a 10% incline at 3.5 mph. The peps help release ffa (fatty acids) into the blood stream (which normally takes 1-1.5 hrs. after your shot for peak release) and then the LISS cardio burns off these fatty acids thus eventually leading to a leaner physique while HOPEFULLY holding on to lean muscle tissue. If one desires to burn even more ffa's then staying fasted a couple hrs. after your cardio can help in this regard. Anyhow, this has worked for me and I thought it might be a help to some.

I've done both.
I like the feeling after fasted cardio in the morning, like you're ready for the day! Its a weird feeling...

You're right, after morn fasted cardio I typically get this euphoric feeling...love this feeling!

The effects of cardio are cumulative...when it's done makes very little difference.

[oatmeal69]

I'm not making ANY statement of fact, just my own empirical observation. Which is that I haven't noticed that I burn off more fat when I do cardio fasted. LAst cycle, it is all I did. Morning cardio on an empty stomach / water only. With my current cycle, it's PWO. Gonna wait until the end of my cycle and get off creatine to see what's water and what isn't, but I'm feeling kinda lean anyway. I'm guessing I'm at about 13% right now.

I, too, have been looking for an answer to this and I may have found one a few days ago! It claimed ~20% more fat calories burned during fasted cardio. I need to find the article so I can quote the university that did the study. I'll try to find it and post it.

https://www.inkling.com/read/textboo...84/figure-84-4

i cant copy the chart here, but if you follow the link, the chart shows that as exercise progresses, glycogen stores decrease, and the percentage of fat usage is increased.

it helps to explain why people believe that fasted and pwo cardio is better. the reasoning is not that glycogen stores are completely depleted at those times. as the glycogen stores decrease, fat usage increase. it does not need to be completely depleted for the statement to be true.

i am aware that there is a recent study done to show that fat usage during fasted cardio is more than fat usage during fed cardio only after 2 hrs of exercise. but i am not sure if that result has been repeated by other researchers or if the conclusion is correctly drawn from the study design. but it seems like that study and its conclusion has not made it into Physiology textbooks yet.

Im just going into 2hour intense weight workouts into half hour recoup including ashake and then into (3 times a week) either hiit 30minsinc warmup n stretch outs (w+s)/circuit training 45mins inc w+s/ab attack 30 mins inc w+s
I think these questions will foremost be different for everyone.
Personally im too scared at losing any muscle mass to go hour plus on cardio or do it without something to assist my routine and ensure im always topped up (atleast a bit), the shake ensures i dont feel toooooooo heavy prior to the hiit style training methods i use in all three excercises. I was gunna post to ask if anyone else has found training routines that assisted them with burning a lil fat but still gain good mass. But im sure ppl are full of fantastic ideas. So ill keep nosin around.
Great thread!

Edit. I gym atleast 5*week withoutfail.
Used to do 2-4 hours dependent if i hit oneof those days i simply dont think ive hit hard enough. N go back for more. Or have a meal or another group who wanna train. Before this week i only did my 20mins b4 and after weight training on step machine rotating on only**glutes/calves/quads. Taken a while to master!

Why do you think your glycogen stores are being depleted are you eating a keto or carb depletion type diet? If not then your glycogen stores are not getting depleted from whatever fasted or post WO cardio you're doing.

Iirc the average human stores over 200g glycogen in the liver and 400g in muscle tissue so much more for someone who has higher than average LBM. That's 2400cals of glycogen that's stored ready to burn even when fasted. You're not depleting your glycogen stores from 1 fasted cardio session bro.

I'm not sure where you got those numbers from.. I have never heard of 200g in the liver. Maybe 100g. Also these are maximum numbers you are presenting right? Unless someone is eating 800 carbs a day they are not going to be anywhere near this.

How Long Does Glucose Last When Working Out? | LIVESTRONG.COM

[Sgt. Hartman]

I was going off of memory but according to your link humans store 100g (400cal) in the liver and 400g (1600cal) in muscle for 2000cal total.

Must be some sick cardio sessions to burn that many cals to deplete glycogen. Not to mention your body never burns exclusively glucose, even at high hr it's still burning a mixture of fatty acids and glucose albeit more glucose as hr rises.

Again these numbers are maximums. An athlete or bodybuilder or almost anyone who is on even remotely what is considered a diet isn't going to have their glycogen stores topped off. Your assuming glycogen stores are topped off at these numbers.
Even so when you do cardio at lower intensity (fat burning zone) you burn more calories from fat. A higher intensity cardio session burns more calories from carbs. However higher intensity cardio burns more overall calories, which is more important.
