| WESRMAN's right on.
You need to spend your time lifting more effectively. Doing Deadlift, Squat, Bench and Pull-ups works every muscle in your body. It looks like your ignoring about 75 % of your muscle (lower body). Doing just curls only works your arms. The more you isolate a muscle group the less other groups get engaged in the lift. Try doing these 4 lifts since you're getting bored from your current routine. If you're not familiar with the Dead lift and Squat, find a person at your gym who you see do them regularly. You can get hurt trying to figure them out on your own with poor form.
