Cardio before or after Weight lifting?

You should ALWAY do weights before cardio. ALWAYS.

When you do cardio first all you are doing is burning up all the glycogen in your muscles and then when you go to lift weights all the glycogen is gone and you are out of gas, so to speak.

On the flipside, if you do weights first you can burn up the glycogen and give your weight training all that you've got and then when you do cardio you have a better chance of actually burning fat.

I do weights 5 times/week and cardio only 3 of those days, after I'm done with weights.

If you don't lift weights as frequently as I do, try doing the cardio on it's own day like other people have suggested. Just never do cardio before weights -- totally counterproductive.

1. NO

2. NO

3. NO

4. That's obvious

5. Again, NO

Ummmm... explanation?

The only thing I'd argue with here is that depending on the intensity of your run you may or may not be burning glycogen so that is very circumstantial.

I agree though, weights before cardio always. In cardio, you are going to gain the benefit of the workout regardless of how tired your body really is. With weights, not so much, you have to hit certain threshold to trigger your body to adapt and grow. If you are tired from cardio it is harder and sometimes not possible to hit those thresholds. Just because something is relatively heavy to lift bc of your energy levels does not mean it is heavy enough to cause your body to adapt to it.

AND

Above all else. Never trust advice from someone who has a pet as their profile pic.

You only need to weight train three times a week for maximal benefit anyway.

Muscles can only grow so fast.

Six reps of working a muscle group, repeated twice more at a session, with two more sessions spaced out during the next six days.

Just stop talking now

After.

how much weight do you need to lose?

I would split them up

for example
mwf - lift then 10-15min hiit
tth - cardio
SS - rest

This is what I do, with 10 minute warmup before lift days. I am no expert, but it's definitely gotten positive results for me.

The best trainer I know says do cardio after. Use stored energy for effective lifts and good form (fully focused).

A trainer once told me to decide what my priority is going to be. Do I want to lift or do I want to run? Once that has been decided then perform the activity that is your priority first. He said to do this because a lot of times what we tend to do is cheat ourselves out of the second activity by rushing through it OR stopping before it's completed.

I personally lift and then do cardio. I start with SL 5x5 then head to the treadmill to do my c25k. I have had wobbly days but I finished. My goal is to gain strength and not so much run a 5k in Olympic time. :flowerforyou:

Maybe you should have read his profile...

My background includes: MS degree in Exercise Physiology, ACSM Exercise Specialist Certification, 29+ years experience working in health and fitness, mostly in hospital based clinical and fitness settings

For the majority of people the question of what to do first is moot. Just do what you prefer and what feels the best for you.

If you have more specialised goals (you're a body builder for example) then it's different. That is a small subset of people - it's a niche pursuit.

I did read his profile. Did you also read it? Did you miss this part of it:

The combination of super-long hours, constant travel, high-pressure and fitting in a new lifestyle w/wife and kids pretty much took me from a fit, healthy 47 year old to a typical more sedentary 55 year old with all the associated health issues of the American diet and lifestyle--overweight, high B/P, high cholesterol. When I was diagnosed type II diabetes in March 2009, that was the last straw.

What difference does that make to the subject matter at hand?

Would you take advice from a mechanic about your car when you see him having trouble getting his own to run correctly?

Lulz - now I know you're yanking my chain.

If said mechanic clearly had a history of making cars run correctly, had relevant qualifications and experience then a temporary difficulty wouldn't bother me much.

Knowledge is knowledge

But how do you know if said mechanic has a history of making cars run correctly? Maybe all you know is he has a piece of paper framed on the wall from the mechanics institute of America and a 1994 ford fiesta duck taped together in the back parking lot.

i dont do them on the same days.

This. I do NROLFW M-W-F.... I usually rest T-TH, on the weekends I'll do cardio (if I feel like it... some weeks I don't do cardio at all and I'm still losing). My total cardio for 1 week is maybe 30min.

This works BEST for me when I'm really trying to drop weight and hold onto muscle

MWF: First, Heavy Weight training with compound movements (60 min) with 15-30 minute steady state cardio after.

T,TH: First, HIIT Cardio or other intensive cardio first (60 min), then weight training smaller muscle groups (Bi's, Tri's, Delts, Abs)

When I'm maintaining: I stick to weight days and cardio days.

Lol - it's true, the mechanic could be making *kitten* up but when you've seen a lot of the mechanic's work before it helps matters...

It's true he could have elaborated more on his original response (which I did find hilarious I have to say) but I have also seen him answer the question seriously on many occasions before (this isn't my first rodeo at MFP).

Ok, so maybe we can come to an agreement that our "mechanic" may have went on a meth binge for awhile there and did some shady work. I still think his answer is completely bogus and would like further explanation.

I still deduct points for having an animal as a profile pic. If it were a cat though we wouldn't even be having this discussion, it wouldn't matter what you say at that point.

Urm......cardio has been prescribed for me before weights! Confused now!

Don't be. Unless you are training as a powerlifter or bodybuilder, it won't make any difference.

In all fairness, I tend to react more strongly to what I consider to be "absolutist" statements (you HAVE to do it this way), so I was more abrupt and impolite than usual.

But the facts are that a lot of the accepted "mantras" about weight lifting just aren't true. Most people have plenty of glycogen--enough for 2+ hours of continuous exercise--and they are not going to burn it up in a typical lifting session.

And, if they did, they wouldn't be able to just walk over and "do some cardio". Ever see marathoners staggering around after they hit the wall? That's what "using all your glycogen" looks like--not some happy little muscle guy trotting along "burning fat".

And even if somehow -- via heavy lifting or fasting or whatever -- one can slightly skew exercise RQ to a more "fat-friendly" mix, that does NOT mean you are "burning more fat". The body does not compartmentalize daily metabolism--it goes 24 hours a day. And an important study in 2009 showed pretty conclusively that the body regulates it's fat oxidation in response to overall calorie deficit--if you burn more fat during a workout, you burn less the rest of the day and vice versa, so that, after 24 hours, total fat oxidation is equal. It pretty much dumps water on every exercise "fat burning" theory every posited.

And while it IS true that, when doing concurrent exercise, the first type of exercise performed first in the sequence will likely affect the quality of exercise performed second, that doesn't mean that the effectiveness or the results will necessarily be compromised. A person can do cardio workouts before lifting--even long, hard ones--and still realize increases in strength and muscle mass from their strength workouts. It is then up to that person to decide whether those benefits meet their goals--and for the majority of people, they will.

There is absolutely no scientific nor experiential evidence to support the idea that, for everyone, "weights must ALWAYS be done before cardio". If you know basic exercise physiology, the idea is simply ludicrous.

It is important to differentiate between specialized sport training and training for health and fitness. What is good (or necessary) for the first is not necessarily good (and it is rarely necessary) for the other.
