Just wondering if there's anything wrong with, or any additional safety concerns involved with, doing squats and deadlifts with dumbells. Since I workout at home, squats with a bar are pretty much impossible, so I started doing them with dumbells and it seems to work (though I must admit I am underwhelmed with the size of my legs). I've recently been thinking about trying deadlifts this way, as well. Is this wrong/less effective? I am hoping it will be superior to the prone leg curls I've been doing.
