New Workout Program: Already Feeling It!

Heeeeey guys! I'm so bad at keeping up with this page, I know...buuuut, cut me some slack- I sat on my tablet, cracked the screen, and that's why I'm not posting as often! But I decided to share my newest workout program with you guys. I usually use a program from www.bodybuilding.com but this time, I made my own. As some of you may know, I'm a Sport & Exercise Major at UCF, so I've used the knowledge I've obtained through a couple of my classes this semester, combined with prior experience and recommendations.

Notes:
***Ab Circuit: I choose any 3 unweighted ab exercises and do 3 sets of 15 reps of each exercise, in circuit form, with 30 seconds of rest between each set. For example:
     15 crunches, 15 leg lifts, 15 V-ups, 30 second rest.
     15 crunches, 15 leg lifts, 15 V-ups, 30 second rest.
     15 crunches, 15 leg lifts, 15 V-ups.
***Cardio: (sighs, rolls eyes, and shakes head in dismay). I have not yet implemented cardio into this workout program. I'm still torn between wanting to make huge gains and having a super lean core. However, I do plan on adding cardio, when I make up my mind about my aesthetic goals.

HELP ME:

When I started working out, I weighed about 110 lbs and had the ultimate goal of making muscle gains, while also keeping my midsection lean. I know this is VERY HARD. So far I've gained about 5 lbs of muscle, but haven't made too much progress in my core (AKA I don't have abs yet). I'm looking for suggestions as to how to implement cardio into this workout program, as well as any other tips you would be willing to share.
