This is the way I like to work out. I am a relatively big guy (6'1" 225), and I like to run. I may run for 20-25 min on the treadmill at an 8 min mile pace, and then go do squats, stiff-legged deads and donkey calves. I can't use quite as much weight as if I did cardio later or not at all, but I feel like I'm doing more work and getting much more out of it. It is definitely harder, and the results are good. Why is lifting with depleted glycogen levels a bad thing?
Why do most shun cardio prior to lifting?
Your glycogen stores provide energy for lifting, which explains why you can't lift as much after depleting them with cardio. Working out at a reduced strength level is not conducive to muscle gains.Originally Posted by skyjumper
Besides, your cardio will be more effective at fat burning once you've depleted your glycogen level with weights... so lifting first is win-win.
Also, it is easier to run when tired than to squat or deadlift when tired, so it only makes sense to do the lifting first. In fact, for optimal results your cardio and lifting sessions should be separated, but this might not be an option for you.
Thanks for the reply, but you made some invalid assumptions here:Originally Posted by HemiVision
I lift nearly as much weight as when I don't do cardio (within 5-10 % I'd say), and I'm doing more work, so I am making significant muscle gains.
My primary goal in doing cardio is not fat-burning, but performance (speed).
Says who? Remember, I'm talking about running/sprinting, not jogging. I think this boils down to a matter of preference and goals, but I can't see how cardio prior to lifting is counterproductive as I've seen others suggest.Originally Posted by Vido
It dose not matter if you prefer to run or squat first. When you deplete glycogen stores by doing cardio before the lift your body will have less effective means for fueling the lift, it the lift will suffer.Originally Posted by skyjumper

weight lifting will help your speed jsut fine and dandy...and if your going for speed you dont need to be doing cardio, there are specific things to do when working on that, of which id be happy to help you with just pm me
Also i dont think cardio after a lift is good either, because after your done your lift your msucles are screaming for the food you eat to help em get better...but if u get straight to cardio for an hour then all that stuff goes to you running and not your muscles, which cant be good either....right????
If you want more speed perhaps you should focus on running on a seperate day. Although, I'd think sprints would help speed more, unless you are training long distance or something like that.

Are you suggesting that someone can be a fast runner without running? By cardio, I mean running.Originally Posted by emjlr3
Your muscles do need energy to recover, and they are going to get it. Either from the food you consume immediately after working out, or stored fat.
I appreciate all of your comments, but there is a bias here. Most on this board are focused on getting big (go figure!). I posted my style of working out because there are some of us that strive to be big AND fast AND lean.
Those overly concerned about preserving every bit of energy for weight training and recovery remind me of turkeys or cattle that are bred for eating. They eat and eat so that they get nice and big, but they can't even fly because they aren't trained to do so.
Goodness Skyjumper...you are a little agressive towards other peoples ideas and opinions. Why post on a weight training forum if you do not want people who train for growth and power to respond to you?
Anyway...regarding cardio before weights. I want to make a distinction between "hard work" and "tension". Hard work is sakting up a hill. Hard work is training on an empty stomach. hard work is doing 15 sets of 25 reps. The ONLY thing that stimulats muscle hypertrophy is tension through the muscle in question. That tension trigger level varies depending on how well that muscle is developed already. A huge percoral muscle will not trigger growth from having to bench press 10lbs.
If your muscles are glycogen depleted they lack energy/fuel to contract effectively and efficiently.. When this is the case full fiber recruitment isnt going to happen and you will not be able to put a high enough tension through the muscle to stimulate growth.
Pain, soreness, burning..."hard work" is just lactic acid bulidup from the muscles either working anerobically or running out of glycogen. Neither one of these mechanisms promotes hypertrophy.
After all that, from what I understand you are looking to be able to sprint faster. Im sure you know as well as I, that sprinters have fairly powerful bodies with good LBM to help with the mechanical aspects of the sprint. If you want to grow the body effectively then training for growth is best done before glycogen depletion and lactic acid buildup. Obviously to increase your speed....then sprint training is the focused requirement. Bodybuliding does not make sprinters....sprinting does. The bodybuliding will help though.
Good stuff, thanks. As far as your 1st para, not sure what you mean, I clearly asked for responses from others.Originally Posted by Augury
What do you mean by "more work" ? If you're lifting less weight for the same or fewer reps, you're doing less work.Originally Posted by skyjumper
you should try to jog lightly to warmup or if it has to be intense preworkout do a cardio that doesnt highly involve the muscle groups you are working.. then after the workout get some protein and do your hard cardio an hour later or a few hours before...

yea dude your sorta mean ...ill have you know im probaably stronger then you, have less bf then you, run faster then you and jump higher then you...so i know what im talking about......to get faster and jump higher you dont do "cardio" per say, you train your fast twitch muscles fibers to be better...by doing so you dont run for long distances...you do short explosions workouts to help accompish this, and is aurgry said...and like i said....if u go and run for a whiel then lift...thats not a good thing..you either do one or the other..or your not going to get the reults out of either that you want

This whole concept is a valid point HemiVision and you are right. But its one that confuses folks all over the world. Its the difference between "percieved work" - what you feel you are doing/how hard you feel you are working....and actual work done as described by physics.Originally Posted by HemiVision
Work done = force x distance moved. Thats the physics. however if i tell you to pick up a 25k dumbell and hold it out at arms length and hold it real still...according to physics you are doing no work whatsoever. Distance traveled is zero. Your muscles are not changing length...they are holding a weight still. However not very long after this, you are going to drop that weight and come hit me becasue it REALLY REALLY burned and hurt you to do it. Why? Becasue you are resitisting gravity's constant downwards acceleration, even though you are not movng the weight at all. You are still having to cycle muscle fibers...as the ones holding the weight still tire, they relax and other fibers in the same muscle are recruited and take up the slack. You get lactic acid buildup and it eventually burns so much you will drop the weight.
So, its perfectly possible, if you are in a state of mild to medium exhaustion (post cardio activity) to do a milder weight training routine than you could have if you were rested but still percieve you were working much harder than the heavier but rested session. The reality of it is that physics disagrees. You FEEL you are working harder, you are more tired, you are panting and sweating...but these things do not stimulate muscle growth. Tension does. The rested, heavier weight training session moves higher weights/loads (force) over the same distances as the other, more "exhausting" but lighter session and so in the heavy session you do more mechanical work. Thus you stimulate the muscles more heavily for a growth response.

emjlr3 I'd be glad to take you on head-to-head in the sport of your choice anytime, anywhere. You did suggest one thing of value though, what do most mean when they say "cardio"? I should have been more clear about that. I am training to perform well in a two-mile run, with a powerful, sprinting, kick. This is the distance for the Army PT test. It is a constant struggle for any career soldier to get and stay big while maintaing the ability to run two miles in under 14 minutes (no juicing either).Originally Posted by emjlr3
I've been asking this same question in various forums for years, brought it up during personal training certification, done research in the library and online, etc. This is the best explanation I have ever received. You spelled it out so that even I get it. Thanks.Originally Posted by Augury
Now this question: to maximize that growth response, how much recovery is required prior to running hard again? A challenge for me because to be a good two-miler/sprinter I need to get probably a minimum of 20 miles/week.
With this in mind, try to explain the Weider pre-exhaustion principle.Originally Posted by Augury
Im just a lowly anatomist/physiologist in the making. If you tell me what the weilder pre-exhaustion principal is ill have a shot at explaining it (or being baffled by it). Im assumig from the post that it flies in the face of what i said. Im happy to have a go though.Originally Posted by Vido
Hmm. As the months go by people keep developing different answers to that question. The fashionable number seemingly bandied about right now is that protein synthesis and growth is pretty much done after 36 hours. I would have thought that sprinting practice (for functional strength) was more important to you than hypertrophic growth though....and so as such i would not worry overly. Do your sprinting the day after the weights. that will give you 24 hours. Just feed well.Originally Posted by skyjumper
Im probably going to get people screaming at me saying that it takes 72 hours for your muscles to recover etc etc. I didnt make the 36 hours up...im pretty sure i read it over at the HST site or bodyrecomposition (or both). Besides recovery is what? when you stop feeling sore? when protein synthesis has stopped for the muscle? Many athletes train on sore muscles every day. Its an interesting area of discussion that i like read about. I by no means claim to know a "correct" answer.
You "pre-exhaust" the muscle you are working by doing an isolation movement before your compound movement. An example would be doing flyes, and then going straight into a set of bench. You would not be able to lift as much on bench, but the idea is that the target muscle has already been fried. The premise behind the principle is that it is usually not one's chest that fails on a set of bench, but one's tris or shoulders. This hopefully allows your chest to be the determining factor in how many reps you can pump out.Originally Posted by Augury
Weider never said to use this every workout, but to incorporate it once in a while for a change. I only bring it up because it basically goes completely against the grain of your explanation of what causes hypertrophy.
Of course you can do both. Ignore the people who say otherwise skyjumper. Basically it depends on your goals that session. There are athletes like rowers, boxers and sprinters who will train up to ten times a week and will be lifting on 3 out of seven days and they will be [I]huge and fast[I]. On your weights days it is probably best to cardio afterwards and keep it light(ish) if you are looking for a really good weights session and do weights afterwards if you want to do hard cardio that day and be fresh for that. I have done weights sessions after 60min cardio and still produced results. The way these sort of athletes who "have it all" manage to do so much endurance work and yet keep their muscle mass is by eating! I know that international rowers eat over 6000 calories a day (which is mostly carbohydrate) and these guys are 100+Kg. What I'm saying is, doing both types of training will slow down your muscle gains but not stop them. And you have to eat more and sleep more to recuperate.
