I have bad knees from football in college so I can't really run hard on pavement without having to ice my knees for an hour after doing so. So I have a treadmill and I was wondering something. If I run sprint for 1 minute and then walk/jog for 2 minutes for about a half hour to 45 min. is that sufficient? Or am I not even really burning any fat? Thanks in advance.
