Haha. Well whenever you want to cut (I say wait a couple to a few months) come back to me and I'll explain everything. I must warn you if you ever decide to come after me I'll knock you out and steal your Bane mask.
When you lift weights you want to change your workouts every month. If your muscles are too used to the routine then you'll hit plateau and your progress will slow down.
Do 5 - 10 minutes of cardio (such as elliptical or treadmill) to warmup before each workout. Also stretch your muscles before each workout, especially your shoulders. Follow this routine for the next month. And make sure to have a spotter. Especially for the bench presses and squats. If the weight at 7 - 9 reps is too heavy for you then don't hesitate to bring the weight down and do more reps. Just be careful with everything.
Mondays:
Dumbbell Bench Press - 1 set 15 - 20 reps. This is a warmup set. Don't include it in your 45 min. time limit.
Dumbbell Bench Press - 3 sets, 7 - 9 reps - rest 80 seconds between sets.
Incline Bench Press - 3 sets, 7 - 9 reps - rest 60 seconds between sets.
Wide Grip Push Up - 1 set to failure
Triceps Cable Pull Down - 3 sets, 7 - 9 reps - rest 60 seconds between sets.
Seated Dumbbell Triceps Extension - 7 - 9 reps - rest 60 seconds between sets.
Do any two ab exercises of your choice. Use ab machines w/weight to make the exercises more intense and to cut time. Do 3 sets each and as many reps as you want. Rest 60 seconds between sets.

EDIT: If you don't know what some of these exercises are then check out the websites below. They will explain the exercises and show the proper form.

Or you could search the specific exercise on YouTube to see how it's done.
And if you want you could do another ab workout (weight free) at home on Saturdays. It would take about 15 minutes. No equipment required. If you want this bonus then let me know.
And make sure to keep a journal with you during workouts. Like a small notebook and pen. Write down all of your numbers so you could keep track of your progress throughout time.
And you might want to look into creating pre and post workout shakes. If you know how to.
