Yes, thats sounds right.  The theory behind it is that low weight with high
reps(10-14) will 'tone' while high weight with low reps(6-8) will build more
mass.  I liked the idea of putting on mass and getting 'big'.  I wouldn't be
losing as much on the scale, but I would still be losing fat and gaining
'size'.

Gaining muscle and working out is a great thing.  Fat does nothing when
you're resting.  There are always muscles doing something, burning calories.
More muscle = higher metabolism.

Make sure you do a 'warmup' set of light weight before you actually start.
This will also help to warm up the muscle, get it stretched and ready for
the workout, and start the blood flowing.

When I was going to the gym religiously, I would do a cardio in the early
morning and weight train at night.  I found that I would get a better
workout if I did a quck cardio just before weight training; .  It helped
warm my muscles up for the rest of the time at the gym and got the blood
flowing too.

I would work out with *at most* two body parts per day; 3-4 excercises per
body part.  You don't want to overtrain though, you'll be doing more damage
than good.  If you're just starting out, start with good habits and good
form; Bad ones are HARD to break.  Don't do so many excercises, but do them
perfectly.  No swinging around to get that last curl up.  No herky-jerky
crap to get that last press up. Just smooth and controled movement.

Don't try to blast out the workout as fast as possible.  That 30 seconds was
most likely between 'sets' rather than between reps.  So do your first set
of reps nice and smooth, then take 30 seconds for a breather, then do your
next set... and so on.

My lifting schedule was:

Day 1:
Chest and Tri's.  Chest workout would be Incline Bench, Flat Bench, and
butterflies on the 'cables'(2 excercises... one moving from low to high
using the cables on the floor, the other moving high to low using the cables
at the top of the machine.  Tri's would be Pulldowns using the 'top' cables,
skull-crushers using a bar, overhead extensions using the 'low' cables.

Day 2:
Back and Bi's:  Back workout would be Rows using the T-bar, Seated rows
using the lower cables, and bent-over rows using dumbells and a bench, and
lat pull-downs. Bi's would be Curls using the preacher bench, 'free curls'
using dumbells and the incline bench, and standing curls(back against the
wall, curling a straight bar)

Day 3:
Legs and Shoulders:  Leg workouts would consist of squats, incline sled
(laying on my back pressing up), leg extensions(on a machine), leg curls (on
a machine), and calf extensions (either with dumbells in your hands, on the
sled while I'm doing presses I would just press up to almost top then flex
my calves and push out my toes, or on the machine)*.  Shoulder workouts
would be military press/shoulder press with a straight bar, 'arnolds'
(shoulderpresses with dumbells... start with the dumbells in your hands.
palms facing you.  press up and rotate your hands so you end the excercise
with your palms facing away from you at the top of the press), butterflies
(arms at sides, then brought straight up to shoulder level at your sides),
and shrugs (either with dumbells or using a straight bar)

Day 4:
OFF, just cardio

Days 5-7, repeat days 1-3

Good, thats progress. Keep it up!

When you lift, do you just go to 10 reps, or do you go until failure(on your
last set)?  If you're not failing at 10 reps (not being able to do one more
or even finish that last rep on your own), try 12 reps, or 14 reps.  If you
can do 14 reps with no problem, raise the weight. Try doing 14 reps on your
first set, 12 on your second set, then 10 on your third.

I liked to stretch before and after workouts and do cardio before.  When I
was done with a session of weight training, the last thing I felt like doing
was a cardio.  I also did an ab workout every day.

-Dough
* I'm a fanatic about my calves.  I did them every day too.  It was most
likely over-training, but I loved the 'burn' and my calves were always
'shredded'.

the first time i started lifting (years ago now) that is what i did and
i had good success with it.  i prefer to lift a little heavier now and
not do so many reps.  

30 seconds between sets, not between each rep.  

keep at it, Marsha.  you won't be sorry!
