Week 1 Day 1

So its offically day 1 of my workout I've been saying this for months now. Every Monday I say to myself okay this is day . Then by Wed. I give up because I ruined my diet or I was too lazy to go to the gym. Then I tell myself I'll start again next month.... well I'm offically starting to break the cycle. Today is Thursday and its day 1 and I haven't ruined my diet yet. I've decided to take it a day at a time and weight myself every monday. Sundays will be my rest day, I will stick to this I have no choice. I can't continue to live this lazy butt lifestlye. I'm so excited and nervous but I know can do this. so my goal weight is 115-120 pounds I'm 5'7'' so thats kinda small for my height but I know I'll end up looking great. So anyways I went to the gym with my friend, he is a personal trainer. He decided to help me out, we did 15mins of cardio on the eliptical, then we lifted weight for our shoulders and back,we did abs workouts (300 of them ive never done 300 total of abs in my life).I just pushed threw it like nothing which felt great afterwards. I wish we could have done more cardio but I guess thats because I am a cardio freak. I'm scared if I lift weight (espeacially heavy) I wont lose any weight I'll jusr gain all this muscle and look like a guy. But everyone including the internet has been saying that you need to lift to burn fat as well as doing cardio. Since I told him I wanted to do more then 15mins of cardio. We are offically running to the gym from my house which is about a 2 mile run. Then running back home afterwards by the time we are done thats about 4 miles total. I know that once we move into the apartment I wont be able to keep this routine. Because I'll have to drive to the gym but I'm just trying to making going to the gym a part of my daily schedule. Even though I know my friend will not be personally training me probably after next week. Thats fine he is helping me now its keeping me motivated to get in the car and go workout, Which is what I need. Hopefully I can drop weight a little faster then 2 pounds a week. Even though 2 pounds a week is the healthy way to do it. I want to drop atleast 5 pounds a week. I know once I get into a certain weight area, I will start dropping less weight at one time. But I really want to get out of the weight area that I am in right now. I dont know if I am comfortable enough to put how much I weight right now. I know I have a long way to go. I will be putting progess photos up every month so I can look back and see how far I've come. Well i'm also reading the book Reshaping It All by Candace Cameron Bure. Its a motivational book for fitness, but it also has to do with putting god in your weight loss journey. i'll keep you guys updated :)
