Front Plate lifts
Complete 8 sets of 8 reps after the smith press. do a weight that is comfortable, and do not increase with each set. As you get stronger, you can try to integrate a superset with plate lifts, and smith press. If you do, try to match your sets and reps of plate lifts with your sets and reps of smith press.

Finding your start weight is the hardest, and this may take a couple workouts to figure out. I usually feel warmed up, around my fourth set. your first four sets should be fairly easy. the last four sets should get much harder
The clue that you chose the right weight, should be your burnout point. You should burn out on your last few reps, of your last few sets. If you complete all 8 sets of 8 reps, you can start a little heavier. Increase each set with no more than 5lbs. This means using 2.5lb plates. If I am not too proud, you shouldn't be!
Be sure to review proper form for the smith press, and stay disciplined!
I do the reverse fly with plates. You can do them with dumbbells if the weight increments will work for you. With isolated workouts like the reverse fly, pull-downs, or lateral raises, lower weight, and higher reps are great way to start. 5 sets, of 10 reps will be a good starting point. You can adjust from there.
