Is it good to run after lifting?

Is it OK to do cardio after lifting?

Do you lose gains if you run after lifting?

Can you lift and run in the same day?
If you mean lift weights and run the same day, that's fine. Or you can do a different days. There's really no best way to do it and it's up to the individual. You may as well break it up, but as long as your diet is keyed in and you're getting the properly balanced cals in/cals out - it doesn't matter a whole lot.
