For women that want to tone I would recommend dumb bells, cause that is what I have used... I started light and worked my way up. Curls, Tricep kickbacks, Shoulder presses, Flys. You can see toning workouts with dumb bells one youtube. I started with 2 sets of 10-15 reps.... If I can do more, the weight isn't heavy enough. If less than 10 rep, the weight is too heavy. My arms look 100% better. the jiggle is gone, and I still have 30lbs left to lose out of 60.
ETA- don't forget about push ups..... they really work those arms....

To build muscle, you want to lift a fairly heavy weight. I'm going to say something that works for men, but I'm sure it will work for you too since it's a fairly simple principle:

You want to eat a little more than maintenance with whole foods and a good amount of protein and carbs. You'll probably want to stop doing much cardio, or at least keep it separate from your strength training on different days, stripping off excess calories if you ate way too much. Do not go down to your BMR as you need calories to feed growing muscles, and your body will want those valuable calories first before partitioning them to muscle mass.

When you do lift weights, make sure you're only able to do about 8-10 reps (until failure, or not being able to do another rep in good form) of the heaviest weight you can lift. Then, go down by 2 reps per after each rest (ie. 10 reps, then 8 reps, then 6 reps, then 4). Do this for about 4 sets on the muscles you're working on that day and only have about 8-10 seconds of rest between doing reps, and no more than 5 min of rest between sets. At the end, you want the muscles you're working on to feel tender, and perhaps even sore the next day. Wait at least 72 hours before working those same muscle groups again.

You want to do this until you can do 12 reps of that weight fairly easy and then increase by about 5 lbs until you're back to 8-10 reps until failure.

This has worked for me since reviewing vids on YouTube from "sixpackshortcuts" and I've noticed quite a difference. Do it until you're happy with how big your muscles become. A whey protein shake within 20 minutes after strength training will help you along, too. Protein should be your first priority while you're getting that muscle up.
