Hi everyone. I am 5'8 and 140lbs. I started working out september '04. My starting weight was 152. In the first month I lost 10 lbs, but since then I haven't lost any weight. Why is that. I go to the gym at least 2 times a week (usually 3-5 times) plus I'm in a volley ball league. I always do my cardio and lift weights. I would like to lose another ten lbs. That's where I was before I gained weight up to 152. Can someone help me?

Could you describe your daily diet (what, what time, how much) and exercise routine (lenght and type of cardio, what weight training exercises, number of sets and reps)?
Have you made any changes to your diet/exercise routine since you started training?

Ok my diet consists of pretty much 2 meals. lunch and supper. Lunch is usually a sandwhich (subway often) and water or milk, occasionally chips. I do eat a lot of fruit. i dont focus on diet so much because i am only 18 so i dont think i need to worry abuot it, i eat pretty healthy compared to a lot of ppl.
For cardio i either go on the treadmill, elipticalls, or bikes. bikes and elipticalls i go on for 20 minutes no stopping. I'm not good at running so ill warm up with walking on it then run as long as i can then walk a lil bit until i can't do that anymore and thats abuot 15-20 minutes.
For weight training I go on almost all the equiptment. i dont know what they are all called but i end up working inner and outer theighs (60-80lbs 3 sets of 15) pecks (75lbs 3 sets of 10) shoulders and upper arms (45lbs 3 sets of 10) back and arm machine (45 lbs 3 sets of 10). then I do love handles with (15lb dumbell) and do 50 reps. i do the bra bulge with a 10lb dumbell so far and i do 4 sets of 15 on abs with a 4kg ball.
Thats my routine and i always add weight to upper body and im trying to thin out my legs and theighs.

from when I started i have eaten 1/2 of what i ate before and i have added more machines to my routine and weight.

sorry its so long but i need to know what im doing wrong

OK. The first problem is your diet. Two meals per day are not enough. If you eat less, your body may react by slowing down your metabolism. Therefore, you should try eating 6-8 times a day. Smaller portions than before, but I would start with a proper breakfast (oatmeal, egg whites, some fruits are good examples). Then eat a healthy sandwitch later in the morning (whole grain + vegetables + lean meat). Lunch - e.g., grilled meat, whole grain or brown rice or potato and vegetables. Eat again in the afternoon - a healthy sandwitch like I described above. Supper vegetables with lean meat. Don't think you don't need to worry about your diet because you are 18. Everybody even kids should eat healthy because we know what is the result of unhealthy, high-fat/processed food/etc. diets.

Regarding your exercise routine: you should be more organized. Don't try to train each muscle group every time, but, instead, focus on certain bodyparts during each workout. For instance, day 1 chest and back, day 2 legs and calves, and day 3 arms and shoulders. You can train your abs every time you want. Allow at least two rest days for your body because recovery time is when development is made, i.e. not when you are in the gym. With regards to your cardio, try doing a 3-min warm-up, followed by 1 min normal-speed running/bike, then 30 sec faster running/bike, 1 min normal, 30 sec faster,..., and 2 min slow down in the end. If you are able to do 15 min, that's fine, later you will be running 20 min or even more.

Hope I could help you. If you have any questions...

What kind of lean meats are there?

Chicken/turkey breast, lean cut of beef, fish and seafood.
