When is the best time to do cardio while weightlifting? Before you work out or after you work out? I have heard bad things about doing cardio after a workout, so would that mean it is alright to do some before you workout?
Or is it best to do cardio on a completly separate day when your not going to weight lift?
no, you ALWAYS do cardio AFTER weights, or on a separate day.
if you do cardio first you deplete muscle glycogen, leaving you with not enough fuel for a good weight workout.
plus, you start pushing the body into a catabolic state as quickly as 40 mins into an exercise period. if you did cardio for 30 mins, and then weights, you could be catabolic by your second exercise. not good.
So why does that mean ALWAYS do cardio AFTER weights?? Weights deplete your glycogen stores as well. Your gonna be catabolic while doing your cardio. From a strength perspective I can see why weights first will be beneficial though.
I do heavy cardio in the morning (rowing), bout 6am. Then lift at 2 pm, I do that M-W-F, and I do HIIT sprinting at night for 25 minutes, 5 times a week. My lifting sessions are always good, provided Ive had some sugar. and Im usually pretty good for the HIT.
Its up to you, try both, try whatever, see how your body eacts, if you can take it, then do whatever you want.

Being a strong teenager means nothing.
My wrists hurt, but some people don't have wrists to be sore. My knees have tendinitis, but some people don't have legs to get tendinitis in. I seem to be going backwards with training, yet some people can't even walk let alone lift 400 pounds on a daily basis.
Dust out the vagina, and keep on lifting.
You leave time to recover between cardio and weights.
I agree with trying it out if your training has room of expermenting then do it. Cardio before may push you harder on the lifts and be more challenging.
cardio can use fat for energy...weight training cannot. so use glycogen for weights first...cardio will find a way to get energy.
you'll also notice, I don't recommend both in one day, to avoid the catabolic effect from training for too long a period.
of course, you could just sip a dilute PWO shake as soon as you start cardio after weights, and fix nitrogen balance to avoid catabolism. some people just don't like that idea, or can't drink a sweet shake while running cuz it makes them sick.
