My excercise schedule for a week for my age?

Right now Im 13, weigh around 95 pounds, about 5'2" and lift 8 pounds. Anyways my old schedule was:

Mon, Wed and Fri - I do 5 sets of 20 pushups, 7 sets of 35 crunches, and 4 sets of 20 dumbbell flyes
Tue, Thurs and Sat - I do 3 sets of 15 bicep curls, 3 sets of 15 tricep extensions, and 4 sets of 20 bench press dumbbells
Mon through Fri - I walk for half hour for cardio exercise
Sun - Take the day off and don't do anything


Anyways my new schedule is:
Monday, Wednesday and Friday - I do I do 5 sets of 20 pushups, 3 sets of 15 bicep curls, and 3 sets of 15 tricep extensions
Tuesday, Thursday and Saturday - I do 4 sets of 20 dumbbell flyes, 7 sets of 35 crunches and 4 sets of 20 dumbbell bench press
Mon through Fri - I walk for half hour for cardio exercise
Sun - I take the day off and do nothing

Is my new schedule better then the old, or should I stick with my old one? Also will what I'm doing right now stunt my growth?

If this schedule is bad, what would you recommend for me?

Also, for you guys with abs around my age or got abs at my age. Do you mind telling me what you did to make your abs visible? Like what exercises did you do on certain days and how long did it take for you to see results? And if you worked out the lower abdominals, or just did crunches? Thanks, would REALLY appreciate it.

Just keep working out hard and make sure you're feeling the burn. Your muscles should be sore the following day. It is pretty unlikely you will stunt your growth unless you're taking steroids - make sure you're building all natural. Lastly, you won't see your abs unless you have a low body fat %. I know guys who aren't necessarily very strong but have very low body fat % and you can see their abs. Since it sounds like you're very skinny, maybe packing on more muscle would help. Try doing leg lifts for additional resistance on your abs. Also, don't worry too much, since you're still growing - it might be hard for you to pack on much mass for a few years.

ok 1) add more weight make it about 15 lb but if u want to be bulk instead of cut use 20
2) add more ab work outs u might not feel it so much with just crunches... personally i feel the bicycle a lot more than crunches
3) also when u do crunches and stuff add a dumbbells and do it
4) instead of walkn for 30 mins run for 15
5) hold weights when u run
6) and try different types of push up ex. diamond, declined, and inclined
