I started my dieting routine almost two months ago. I'm 5'6" and weight 160lbs. when I started.

I've been jogging 2-3 miles a day and I'm down to 145-148lbs. Just last week I started weight training. Need your advice, is there a difference between using the free weights or the stationary weights?

I start off by jogging 2-3 miles on the thread mill ( I used to jog outside when it was cooler) then I do the chest press (10-12 reps, 10 sets) and 100 sit-ups. My chest is a little bigger (a little) and I can finally see my rib cage and the inner part of my stomach.

What can I do to build a bigger chest and a flatter stomach. Many thanks.

For one, you should do 10-12 reps with 3 sets. 10 sets is way too much. btw, is chest press the only excersize you do? because you need squats, deadlifts, pullups, etc.

Ditto Dave:

If you're only running, benching, and doing ab work you're going to open yourself to excessive muscular imbalances. A balanced workout is very important. Your upper body really only does two things, it pushes and it pulls. While this is TREMENDOUSLY over simplified, it's true. You need to make sure that you're providing your body equal opportunities to push and pull (IE: If you pushup then you should pullup, etc).

As for your legs, focus on compound movements that utilize the highest number of muscles (Squats, deadlifts, lunges, etc).

I am lifting and endurance training. You may find that if you shorten your run on the front end say maybe 1 mile, you will catch your body on the way up "the hill" verses after it settles into heartrate.

this has given me a 'superman' feeling with the weights. then the weights make me feel even better. SO, when I go back to finish the other miles (in your case 2) I feel like this big ol' muscley running fitness junkie!!!

WARNIN: there may be some health hazards in my training techniques.

So, are you lifting to improve endurance in running? If so I'd like to hear more about your wokrout, my friend was thinking about sometihng similar for cross country.

sometimes I run a mile and then lift and then run the 2nd mile before I leave the gym

i play basketball regularly too so I'm not too worried about my legs

i don't want to bulk up, looking to get a defined upper body

You should bulk first then cut to get defined, toning with high reps and low weights is a bit of a myth. you look tone when you lose fat to show the muscles laying underneath. and running around playing basketball and running in general doesn't build leg muscles like squats do. It is important to lift with your whole body, not just upper (trust me I know)
