doesn't work like that - the amount of weight you're using determinees how much muscle you'll grow. if you keep your reps in the 10 - 12 range, you should be able to avoid bulking up.
but no matter what, when you do weights, you are causing damage to your muscle tissues. if you follow a weight workout with a high-intensity cardio workout, you're causing even more severe damage that will take longer to repair. if you want to do cardio after weights, you have to keep it low to
moderate intensity. that will have the added benefit of possibly reducing
muscle soreness. keep in mind, though, that you have a window of 20 - 30 minutes during which nutrients will go directly toward repairing damaged tissues. that's why it's generally best to separate them - you want cardio to burn fat; that means you want your system to be carb depleted. but you want your muscles to repair themselves in the shortest possible time; that means you need carbs.
it's just a lot easier and more effective to do cardio first thing in the morning on an empty stomach and weights later in the day after you've eaten.
