Former personal trainer here.
Don't do strength work for any muscle group every day. Your muscles need rest in order to get stronger. I recommend no more than three times a week for each muscle group. So what you're doing is actually counterproductive.
Your muscles also work synergistically, so you have to work them all and give them all adequate rest in order to get stronger. So don't just work your abs. Pick up the dumbbells, find a beginner full body strength program and go to it. When you are more advanced you can move to split training if you prefer not to do full body on the same day.
You won't get a six pack. Women have too much body fat for the abs to stand out like that, no matter how much you work them.
I gave my DD a basic, begginer full body circuit program that is easy to remember.
Warm up 5-10 min.
squats
pushups (start with wall pushups if you can't do bent leg pushups)
deadlifts
shoulder presses
lunges
bent rows
Repeat circuit
After a few weeks you can add triceps extensions and bicep curls and start doing three circuits if you're able. Once you have been doing three circuits for a while you can add another exercise for each muscle group. Up the weight of your dumbbells if you can do 15 reps. Each set is to be done until you can't do another lift with good form.
You will eventually be doing full, straight leg pushups, and when you can do 15, you need to move on to dumbbell bench presses. The rep range 8-15 is optimal for muscle growth and functional strength. The lower rep ranges are for brute strength and explosive power, which isn't particularly useful in most people's daily life, but if you want that, you can move to that when you get more advanced, but keep in mind that it's hard on your joints. I never do less than 6 reps for that reason. If you go into higher rep ranges (above 15) you start to build more of the type of muscle fibre that gives you muscular endurance, which is actually quite useful in daily life (like carrying a child or anything heavy) so you can add those in as you advance.
