Questions about my excersize routine!?

[drastik]

So every night I do 10 reps of 25 regular crunches with my legs up in the air, knees bent. In between each rep I do a simple 5 push ups. I also do oblique excersizes in addition to the regular crunches. I have been doing this routine for a bout a month in addition to a new diet. I don't eat candy, junk food, or fast food, nor do i drink anything but water and an occasional diet soda. I've deffinately seen results (lost 15 pounds). I don't consider myself fat at all ( 5'10" 163 lbs.), but i would like a sick pack. Is the routine im doing okay for my goal? I would like to start seeing some toning in a month because I'm going on vacation! Should i change anything?

Honestly, the crunches will do the trick! and congrats on the weight loss! Wish I could say the same haha.

I would add some abs twists, Lay on your back with your feet on the ground and your knees bent at about a 45 degree angle, then just lift your back off the floor and touch your ankles, I would recommend at least 40-50 touches/reps
