text: running and weight lifting...? i love to run and lift weights. i want to find the best way to include both in my routine, and still recieve the benefits of both without one messing up the other.  i have heard that running on same days as lifting is okay and not okay. running on an empty stomach in the morning, running as a warm up for lifting, i'm not really sure what is best.   my plan right now  -run 20 minutes on mornings of weight lifting days (3-5 days) -run 40 minutes on days not weight lifting (1-2 days) -1 day rest per week  i want to run, but not destroy precious muscle. can i run when my muscles are recovering without burning them up, and by burning fat instead? is my plan okay, or is there a better method of running and lifting? your plan sounds excellent.  i think you are letting your muscles recover by not weight lifting everyday so there really is no problem with that.  if your plan is working for you, don't listen to what anybody else says!
