Dr.X, all flyes do is fatigue your chest before you hit the heavy movements like bench. I made the mistake of doing flyes for a warmup and it limited me on my bench press. If I was to do 70 lb dumbbells for a warmup, which is the dumbest thing I have ever heard, then I'd probably drop alot of weight on my bench. It all boils down to which exercises are best for building mass. I'll keep my chest fresh and stick to 350 for reps rather than fatigue it with some flyes and then do 315 for reps. :o[/QUOTE]

Actually if I don't do them as a warm up, (and for me I don't start at 70 but I do end up there,) I will spend or I should say waste alot of time warming up with just bench. I workout at 5 am. I have found that it has had no effect what so ever on how much I can bench. In fact I can lift more because of the fly warm up. You might think differently when you hit the 40's. O by the way, just because I can do 70lb flys dosent' mean I'm using all my energy on them. They really are just a warm up for me to losen up the chest/shoulder.
