With such a topic so broad we truly try to cover the basics from all angles in this group. Nothing too big or too small. Nutrition is as significant if not more as exercise is to reaching your goals so learn all you can.
I suggest a healthy diet as a number one priority in regards to meeting your fitness goals to go along with your time in the gym. If you are looking to gain lean muscle, the most commonly used supplement would be some type of protein powder. It is often advised to get 1 gram of protien per lb. of body weight daily for gaining.
So train hard eat clean and maybe look into getting some type of protien supplement if you struggle getting enough from your daily food. Taking Whey Protein post workout is a great time to get 30 to 40 grams within the hour following a workout.
