Aerobics and Weight Training?

[Toast Man]

Hey..

I tried searching for an answer for this (and got 1000 some odd threads to wade through, gave up after a few pages), but I'm wondering how compatible aerobics and weight lifting are with eachother? For instance, is it only one or the other, or is it a good bit of weight training but only a little aerobics as I see many people doing here?

Long term I'd like to add some muscle as I consider myself skinny and lanky, but only up until a certain point. I'm moreso looking towards running as a means of keeping in shape.

Right now I'm running/walking about 40-50 minutes each morning, with weight training 3-4 times a week. How much does this have an impact on lifting? Can I or should I avoid doing the major leg excercises if I'm running anyway? Will running minimize muscle gains?

A few other questions directly related to the excercise itself - should I be running immediately before or after weight lifting? Or should I be running at a completely seperate time? Mainly I'm trying to not compromise my running routine while maximizing how much muscle I will be able to gain. Thanks.

running 40-50 minutes a day may be to much ... the more you run the more muscle fiber you burn up.. (in general terms...)

trying to keep you cardio sessions between 20-30 minutes... for best results you should do these sessions on off days.... but if you want to do them with your weight workouts hit the cardio after your weight workouts..

running really doesn't replace leg resistance training workouts... so do the leg workouts as well

muscle is your friend...try to save every gram of it if you can

As miskiw stated, running on off days will give you the best results. Run in the morning when you first get up, and have whey protein before you run to prevent muscle breakdown.
