Workout routine? Loose weight,Gain muscle,Get abs workout?

I'm 16. Summer is coming up and i wanna be able to wear my bikini. I'm 125-128lbs. 5'5" height. I'm like average i guess. I drink alot of spring water. Thats basically all i drink besides milk every once in a while. I am wanting to start a workout routine everyday in the morning. Whats a good routine? I dont have a bike and cant afford one at the moment and i dont wanna go running in this neighborhood cuz its like bad neighborhood,shootings,drug dealings,rapes,etc. Theres always a cop in the neighborhood. So yea..not safe to exercise outside. If this helps,i got 2 2lbs weights and a jump rope that the handles weigh 1lbs each. I got it for track in 5th grade to exercise my legs at homr to practice for the track meet. Havent been in track since. I'm a freshmen now. But anywho,workout routine? Please and thank you :)
