Thanks to both of you! I have been doing 3 sets, but I tell you, I have to push myself into it. Some of my exercises, when I add a little more weight gives me troubles. Like, shoulder lifts or butterflies, my ribs go out easily and every time I lift heavier I have troubles. My ciro says to stick with the lighter weights for a while before adding more. I do on average 10-15 reps, on the things where I have to use body weight, it tends to be 20+ reps. I need good leg weights, I need more/heavier dumbells, but that all cost money and theres always something more important.

Those dumbells, where you dial the weight and pick up that weight, are they any good? Some times I see them on craigslist and kinda would like a set but there pricey.
