Will this work before the summer, please help?

Hi.


I'm 15 and 140 pounds.





Me and my sister just started to go to the gym, we go 3-4 times a week for about an hour. I do carido for 30 minutes each.








Will i lose alot of weight before summer if i also eat right, and will i look tighter and toner?
