Try to train with weights for 3 days a week and do your cardio on 3 other days.

That might be to much training.

Day one

chest, delts and triceps ( the push workout)

take a day off

Wednesday back biceps

and Friday legs.

That would sound better.

ANd beleive me it would be enought, plus you can build some mass on this too.

Training to much is gonna get you to overtrain and thats the worst thing that can happen to anyone.

Good luck
