Weights, then cardio. Got a link to a good explanation?
Hi. I've always done a warm up, then weights, then cardio. My reasoning is the weights promote muscle growth and the cardio promotes fat loss. I've always thoughts that doing weights first burns up all the glycogen in the muscle tissue, then when it's time for cardio, the only energy left is from fat stores.
Is this generally true? Are there any sites/posts that can explain this better?

That seems to be the way most people do it. Weights then Cardio. I'm different I suppose. I'm 41 and unfortunately I've found that I have to break a full sweat with about 30 minutes of cardio (usually treadmill at 4.3 mph and 5% incline) before my muscles loosen up enough to actually lift weights without hurting myself. Some days my routine seems counter productive because I obviously don't have a full tank of gas when I start lifting.

I read somewhere that cardio before weights restrict gh. I think it was in muscular development sorry don't have a link

Unfortunately, there is no clear cut answer. In addition to the protocol that you mention, there is research that shows the other two combinations are also "optimal."

Aerobic and resistance exercise sequence affects excess postexercise oxygen consumption.
Drummond MJ, Vehrs PR, Schaalje GB, Parcell AC.

Excess postexercise oxygen consumption (EPOC) may describe the impact of previous exercise on energy metabolism. Ten males completed Resistance Only, Run Only, Resistance-Run, and Run-Resistance experimental conditions. Resistance exercise consisted of 7 lifts. Running consisted of 25 minutes of treadmill exercise. Vo(2) was determined during treadmill exercise and after each exercise treatment. Our findings indicated that treadmill exercise Vo(2) was significantly higher for Resistance-Run compared with Run-Resistance and Resistance Only at all time intervals. At 10 minutes postexercise, Vo(2) was greater for Resistance Only and Run-Resistance than for Resistance-Run. At 20 and 30 minutes, Vo(2) following Resistance Only was significantly greater than following Run Only. In conclusion, EPOC is greatest following Run-Resistance; however, treadmill exercise is more physiologically difficult following resistance exercise. Furthermore, the sequence of resistance and treadmill exercise influences EPOC, primarily because of the effects of resistance exercise rather than the exercise combination. We recommend performing aerobic exercise before resistance exercise when combining them into 1 exercise session.

Concurrent training enhances athletes' strength, muscle endurance, and other measures.

We evaluated the effects of concurrent strength and aerobic endurance training on muscle strength and endurance, body composition, and flexibility in female college athletes and compared two concurrent exercise (CE) protocols. Twenty-eight women (mean age, 19.6 years) were divided into two matched groups and evaluated before and after a vigorous, 11-week, 3-days per week CE training program. One group did serial CE consisting of a warm-up, resistance exercises at low heart rate (HR), aerobics, and a range of motion cool down. The other group did integrated CE consisting of aerobics, the same resistance exercises at high HR achieved by cardioacceleration before each set, and the same range of motion cool down. The two protocols were balanced, differing only in the timing and sequence of exercises. Serial CE produced discernible (p < 0.05) increases in lower- (17.2%) and upper- (19.0%) body muscle strength and fat-free mass (FFM) (1.8%) and trends toward greater lower-body muscle endurance (18.2%) and reduced upper-body flexibility (-160.4%). Integrated CE produced discernible increases in lower- (23.3%) and upper- (17.8%) body muscle strength, lower-body muscle endurance (27.8%), FFM (3.3%), and lower-body flexibility (8.4%) and a decline in fat mass (-4.5%) and percent body fat (-5.7%). Integrated CE produced discernibly larger gains than serial CE for six of nine training adaptations. Effect sizes were generally moderate (44.4% of discernible differences) to large (33.3%). We conclude that serial CE produces adaptations greater than those reported in the literature for single-mode (strength) training in athletes, whereas integrated CE produces discernibly greater gains than serial CE. The results suggest synergy rather than interference between concurrent strength and aerobic endurance training, support prescription of CE under defined conditions, establish the importance of exercise timing and sequence for CE program outcomes, and document a highly effective athletic training protocol.
I agree with your assesment. For resistance work, I want to be as primed as possible to maximize the resistance session. If I'm worn down from 30-45 minutes of cardio prior to the resistance session, then I'm going to be in a suboptimal state. Also, my heart rate seems to elevate faster if I do cardio post-resistance work as opposed to when I do cardio work first thing. So, take your pick because the science definately isn't clear.

In my opinion, it all varies from person to person. We at this board have been (and will always be) searching for that program/regimen that will keep us big and ripped. Our body-types are different. We need different foods, different ratios of macronutrients, different sleep cycles, different workout programs, different post workout nutrition, etc.
Myself for example:
Endo/Meso (loosely speaking)
Optimal Diet: 20 carbs, 40 protein, 40 fat (20/40/40)
Optimal Weight Routine: HIT Style Full Body w/ a few intensifiers (ex. dropsets, supersets, whatever) to be performed M/W/F
Optimal workout configuration: 15 minutes warmup/45 minutes weights/10 minutes abs/20 minutes moderate-low intensity cardio
Non-Resistance Days: 45-60 minutes cardio at a moderate intensity
Post-Workout Nutrition: 30 grams hydrolyzed whey/casein providing full spectrum EAAs immediately post workout and a whey isolate/flaxseed shake 30 minutes after that.
It all varies......... I'm still tweeking things...
