It is really hard for some of us to "truly" exhaust our legs with the usual at-home equipment. It's like Cathe says in one of the videos, "getting more than 50 or 60# over your head and on to your shoulders is difficult," but for slower paced workouts like PS Series and MIS, I load to 60# for my legs, and for faster paced (endurance) workouts like LL and PowerHour, I usually only load to 45#. But as far as feeling that, "I can't get out 1 more rep" feeling, it may be difficult for you to feel that with just your at-home barbells and dumbbells, unless you do something to pre-exhaust your legs first. I usually do one of Cathe's cardios prior to a leg workout to help exhaust them a little. You could also try pausing the tape/DVD between sets and do your own pre-exhaust exercise, like front lunges, back lunges, etc. Also, there was a thread about weighted vest that seemed to work as an alternative to loading more weight on the barbell. The weighted vest adds weight to your upper body, thus increasing your load.
But short of gym style machines/equipment, once you reach the maximum weight you can safely get over your head, you're pretty done for increasing the load at home.

p.s. Also, legs are funny, depending on the workout, sometimes I don't feel the "work" until the next day!

If you go heavy enough with LL, you'll feel that burn immediately, but PS, S&H, and MIS can sometimes turn around and smack you the next day!
