Thread: Views on Cardio and weight training in the same night

Your body will continue to use calories to power your run, when it could be using them to repair and build muscle. This is why it may be better to run before hand, and then do your weights. Obviously, running beforehand (speed and distance being the main factors) will affect you weight-lifting performance, tiring you to a certain extent.

Are you changing your calories? If you're reducing your carb calories to aid in your fat loss (even if remaining on a high protein diet), limiting carbs will also limit your muscular gains. If your diet/calories are staying the same, just consider how those calories now have to fuel your running as well as the weight training (and other daily exertions).

just do your run after your resistance training.

yes, you will still burn calories. No, you probably aren't going for a long enough duration to really impact lean muscle mass.

Don't split hairs over something so insignificant.

I seriously doubt running a couple miles, which should be 15-20 minutes, would have a really large impact on your muscle building efforts.

k thanks guys thats all i needed to know
