Quick Advice

[J0kerr]

I am looking for some quick edits/advice to workout

I can only get to the gym 3 times a week and here is what I do:

Treadmill for 30 minutes
Walking at 2.8 MPH
Running every 5 minutes for 1 minute at 7.1 MPH

Then I do the Chest Press Machine - 12 reps/3 sets of increasing weights...If I can do 12 reps in all three sets I increase weights next visit
Then Bicep Curl Machine - 12 reps/3 sets of increasing weights...If I can do 12 reps in all three sets I increase weights next visit
Then Ab Curl Machine - 12 reps/3 sets of increasing weights...If I can do 12 reps in all three sets I increase weights next visit
Then Row Machine - 12 reps/3 sets of increasing weights...If I can do 12 reps in all three sets I increase weights next visit

Should this help me gain a little muscle, get tone, and lose weight?

Right now I have done this for 3 weeks, and arms have gotten slightly bigger (not more tone) and I have gained about 5 pounds. Does this sound right? Am I doing OK?

Make sure you put in some work on your legs.

What is your height,weight and age?
How is your diet?

Your weight workout misses many important muscle groups. If you want to burn more calories while building muscle try doing circuits that include: deadlifts (with barbell), chest press switch each workout between (machine, dumbbells, or barbell), seated shoulder press, and switch between row machine, pulldowns, or pullovers each session. Add abdominal work on a balance ball rather than on a machine. Do 3 circuits resting only between circuits. This is very basic, but gets all the major muscle groups.
