A
beginner's weights program that I just designed when I saw this thread

... 2-4 days a week, in a addition to your usual exercise...
Do all exercises for 3 SETS with 12 REPETITIONS in each set inless otherwise specified.
For maximum effectiveness, sit on a bench with your weights lined up next to you. I would recommend two of each of these: 5lb, 8lb, 10lb, 15lb.
DAY 1 Upper Body
---------------
Bench Press Ladies...Lay on a bench with two dumbells..about 10-15 lb each depending on strength... press up, control down, no throwing the weights.

Back Flies Sit up on the bench with two light dumbells (3-5 lb)...

Bicep curls Sit up tall and curl. Don't bend your wrists.
Tricep Extension Hard to explain...

Pushups Do as many as you can. Girl pushups are okay, too. If you do 3 pushups your first day, try to do four the next time.
DAY 2 Lower Body Don't let your knee extend over your ankle on any of these.. I didn't explain these, I thought they were more self explanatory... ask me if you don't know
Squats
Lunges (3 sets x 12 reps on each leg.. switch back and forth)
Deadlifts
Jump Squats (DO NOT USE WEIGHTS WITH THESE)
Hope that helps you jump into lifting weights... there are hundreds of exercises and techniques but it's best to start simple and get body awareness, knowing what your limits are, before really jumping into lifting... =)
