Go deadlift 300lbs and tell me your heart isn't going nuts.
Your heart will certainly go nuts. But deadlifting won't enable your heart to keep going at 80% for 5 minutes straight unless you do some 1x100@100lb crossfit style deadlifting.
I strongly recomment weight lifting for most people. I'm only suggesting that out of 5 days, do 3 weight and 2 cardio days. And yes, the cardio days should probably be squash, heavy bag or football rather than the treadmill.

I'd rephrase this and say cardio days should be something you enjoy doing. Some people enjoy running on a treadmill. I don't understand how that's possible, but if you like running on the treadmill, more power to you.
On the other hand, if you hate running on the treadmill, don't force yourself to do it! Exercise is a lifelong commitment and doing something you dislike isn't sustainable. Find something fun and do it regularly.
