Put down the 5 pound weights!!!

Put down those little 5 pound dumbbells:
You need to lift heavier weights to see your body change.
Lifting lighter weights ( less than 70% of your maximum effort) for 12 reps or more is only going to produce muscular endurance without much muscle growth, meaning you will be able to lift for a longer period of time ( more reps) but you wont see much muscle growth or change in how you look.

To look "toned", you need to develop your muscle and lower your body fat.
This is achieved by lifting heavier weights ( 70-80 % of your maximum effort ) for 8-12 repetitions per set to muscle fatigue or near fatigue.
