im thinking of drinking an energy drink like Rockstar or something along those lines prior to my work outs.. is this a good idea and if do which is best to drink?

No, Research shows very large negative impacts on performance likely due to rebound hypoglycemia along with other problems. Never supplement with a high GI carb peceeding(60 or less) a workout.

My own research has shown that energy drinks, are made of fail.

I considered many top energy drinks in US, UK and Australia.

ok..... so what iv heard is when you drink a energy drink it gets your heart pumping.. ALOT and when you run and workout it gets it pumping more... which could lead to a heart attack or somethin like that... but thats what i heard drink something like sqwincher. it it is an electrolyte replacement drink

personally i do not lik the foam caused. On a low energy day I like a cool shot of expresso. it's one swallow and it gets me thru to where the endorphins take over.

energy drinks make me foam up, and pills make me feel like a phoney doper of an athlete. so offense to the pill poppers- it's just my opinion- but i'm right.hahahaahaha

I wouldn't suggest an energy drink before a workout for reasons mentioned above, however, you might want to try a cup or two of coffee before a workout.
Research on whether or not we should drink coffee before a workout is mixed but tends to lean in favor of having 1-2 cups as opposed to not.
Personally I find I am more focused and less fatigued when I've had coffee before a workout compared to when I have not.

I think it's definitely something people should try and see if it works for them.

Caffeine before a workout is what I use if I'm feeling sluggish.

Word...2 cups of coffee is awesome before training.
