Help. Need advice on my workout.

stephrivas84

I have realized that I dont know if i am working out correctly. I need advice. This is what I do but i want to push myself more.
I do eliptical (This is my go to workout, trying to add more and more time. right now up to half hour) or
wii fit walking or running( starting doing it with weights to see if i could get more out of it) or
Zumba
Sometimes I do the fight lights out for ps3 to work out my arms.
I just started using free weights at 8lbs and do different lifts that i found online. Should I use a larger weight for shorter amount of time?
I workout 4-6 days a week.
My current weight makes it hard to do intense workouts.
I esp want to workout my arms because that is what is going to be most visible in my wedding dress.
Any tips would be very much appreciated it!
