Rebelyell22....
There has been a lot of great advice given to you. But ultimately what it boils down to is how bad do you want it?
I've spoken of my GF in this thread. Sept 1st 2012 she was 5'2" and weighed 206lbs. July 1st 2013 she weighed 129lbs. 10 months 77 lbs. She is a 40 year old single mom with twins, 3 dogs, and a full time job. If she can do it you can too.
First thing she did was she read the book Body For Life by Bill Phillips and ate off the list. She also incorporated Bill's thinking with regards to keeping track of workouts and pushing her workouts. It's one thing to show up at the gym and go through the motions, it's a totally different thing to show up day after day constantly pushing.
Every morning Mon-Sat the alarm clock went off at 4:30. Off to the gym to run sprints. Don't be the Geico commercial showing the two women on the stepper....going through the motions....push yourself.
In the evening it was weights. A variation of the bench M,W, and F....heavy. Followed by shoulders and triceps. More of an intermediate weight but always pushing for either more weight or more sets/reps. A variation of the squat on T,TH, and Sat. Followed by back and biceps and DL's once a week. Same thing, heavy on the core exercise, intermediate weight on the assistance exercises. Always pushing.....
Sundays she did yoga
You can do it. And I'll leave you with this video which I have always thought was a very motivational video.
