Hi there! First off, congrats on 8 months of consistent workouts! That's no easy feat! Second, this is not exactly the forum where you're going to find a lot of information regarding exercise (no offense to anyone here!). The discussions here revolve more around diet. Having said that, I do have some experience with lifting and aiming to change my body composition. Definitely don't lift for the same body part 2x a day. This will not help you lose body fat but will break down your muscle and not allow enough time for recovery. When it comes to losing body fat, diet is essential.
Have you done much reading on lifitng and diet? A few books I would suggest are Body For Life
and The New Rules of Lifting
. If books aren't your thing, maybe a website like bodybuilding.com
might be a good forum to get advice on diet and exercise.
All the best to you!
