I'm slim, flat tummy, slightly toned arms nothing too great.
I've been on and off from gym for the last 3 years.
Here's the questions:
1) How can I can some good amount of muscle, something that works for you maybe? I don't care about the time frame as long as it works over time
2) 6 pack abs - what's the best way to obtain one of these especially for someone like myself who already has a flat tummy. eating? exercises?
