FITNESS plan, please answer?

i just joined Goodlife fitness center(in canada) and i just went for my first time today.

im 15. and im going to try to eat healthy, and me and my mom go there 2-3 times a week for about 2 hours(sometimes more)
I plan on going to the tredmill(fast walking) for 30 minutes, the recumbent bike for 30 minutes and the Elliptical Trainer for also 30 minutes.
i'm 160 pounds and 5'6. I want to get toner and tighter before summer, do you think this will work? how much weight do you think i will weigh before summer?

For some reason, i want to push myself to the limit, i want to lose weight NOW, i always try to over exercise.
Will i look "skinner" or "slimmer" by the summer? I want to give up sometimes cause i always think i will look fat forever.
How big of a change before the summer?



thanks for your help!

ALSO: this semester i have gym 4th period. And sometimes i will walk home from school instead of taking the school bus. Its a 30 minute walk, and i have to walk up a big hill.

I used to weigh 170, and I got down to 130 in two months. And I didn't starve myself! (I now weigh 140 because I ound a happy medium.) However, the best thing that I did was drop the sodas and drink ONLY water. Always eat breakfast, but a light one. (I always ate Special K cereal with VERY LITTLE milk) For lunch eat small. (only a turkey/mustard sandwich.) Then for dinner eat normal. (but not over doing it. I would have like pork chops, a small salad, and beans.)
Eventually, your stomache shrinks and you just can't eat a whole lot.
If you eat like that plus your excersising the way you say you are, you will drop weight quick.
Good luck!

I was getting a bit chubby, then I started walking/running 4-8 miles every day in my neighborhood. I've been doing it for 4 months now, and I don't look skinny, but I am slimmer (I went from a size 10 to 6). Also, I have more muscle mass. The important part is not to look good in a bikini, but to get yourself healthy.
You should also put emphasis on the food that you eat, rather than just exercise. Foods high in fiber (such as grape-nuts), protein (lean meats such as turkey or tuna) and water (fruit, mainly) will enhance your performance. You will burn more calories, and not get annoying cramps. :-D (I hate those!)

Hope I helped!

those three machines total 1hr 30mins of cardio, which honestly is not needed. all you need is 30 mins on one machine. (5 min warm up+20min at a high intensity+5min cool down) and if you're not tired by it, then the intensity wasn't high enough.
and there's nothing wrong with weight training, that burns calories as well as tones your body. and ofcourse build strength. a lot of girls think they'll turn "manly" from lifting weights. but that is completely false. it all depends on how you train. you should lift lighter weights with the rep range between 12-15. if you can do more, then the weight is a bit too light.

just keep a dedicated workout plan, and diet. be open to learn new things and you'll be fine! but really remeber to be dedicated if you really want it. don't be tempted by your favorite junk foods.
honestly good luck and i hope others here can help!

Change your lifestyle and do this forever. Drink lots of water, walk, run, or swim an hour every day except 1 then do stretching and upper body toning. Eat fruits & vegetables.
