I used to run ~5 miles x 5 days a week first thing in the morning when I was "cutting" and then I'd go lift in the afternoon 5 days a week. My lifts dropped when I started running in the mornings like that, and a buddy of mine told me to get really cut I should run LESS and I thought he was nuts. For the last three weeks, due to a new job I started, the only cardio I've done is 4-5 miles on Saturday and Sunday, and then I play hockey one night a week. I lift weights on my lunch break M-F and sometimes I'll go do some weight work on Sunday night. I have burn more fat, and gained muscle, while doing this new routine. So while I'm not answering the "What's your favorite type of cardio?" question, I just figured I'd share that for anyone who's thinking you have to do a ton of cardio to burn fat.
