Okay you want to gain muscle. Then you will have to go to the gym alot.

My routine is: (10 sets
Day 1. Back(10,8,8,6)(3/4 machines)
Biceps (10,8,8,6)(3 machines)
Shoulders (10,8,8,6)(2/3 machines)
Day 2. Chest (8,8,6)(4 machines)
Triceps (10,8,8,6)(3 machines)
Legs (10,8,8,6)(2/3 machines)
Abs (20,20,20)(2 machines)

Eat healthy stuff.
When you´re done exercising, immediatly make sure you take alot of quick carbohydrates.(like fruit)
An hour after exercising take in protein.

That´s what you need to do. During a workout ALWAYS finish your sets, keep working out until you feel that the muscles are pumped.

Good luck.

Do you have a naturally high metabolism or low? Because if you have a high one, you don't need to worry as much as eating more protein, less calories. But instead want to eat SHITLOADS of protein with SHITLOADS of calories. But basically, all of that stuff about using the machines is totall bullshit, it doesnt build strength the same way barbell excercises do. Read mark rippetoes- starting strength :basic barbell training. There are basically 5 excercises that help you gain weight and build strength and mass, 1 (ABOVE ALL ELSE) SQUATS. 2.Benchpress 3. Deadlift 4.Shoulder Press and 5.Hang Clean These are necessary to mass building. For abs, decline crunches, and machines are okay. Plus, using a barbell works your abs for balance. Your set number should be 3 sets of 5 reps. Trust me, if you read this book you will know what to do. Also, for fat burning, do HIIT, which is you sprint for 60 seconds and walk for 120 seconds and then sprint for 60 and walk for 120 so on and so forth until you cant do that anymore. Supposedly, if you do this sort of cardio training, even after you are done your body still burns calories. If you have any more questions, pm me. I may have a late response btw.
