Check out nikkiolie's thread
. Has some great fundamental tips and a good workout routine for you.
Also, I would really
recommend getting a set of dumbbells. You can buy 10, 15, or 20 pounds for very cheap
and it will help you SIGNIFICANTLY.
Anyways, whatever you decide to do just make sure you are lifting / resistance training at least 3x a week. Feel free to do cardio as much as you want, as muscle "toning" mostly relies on a healthy diet.
And a healthy diet basically just consists of healthy foods and proper math--there's quite a lot to learn about nutrition that I can't really type all in one post, but here are a few fundamental links that will help you vastly on your nutrition journey.
You will probably want to eat 250~ calories less than your TDEE, (the calories you burn) and eat 1.0 - 1.5g of protein per pound of bodyweight.
Let me know if you have any other questions or want me to post a routine made specifically for your needs, but for now I'm goin to bed.
Reminder that we're all gonna make it, brah.
