Anyone that wants to put on size and strength will need to follow a regime like this:
Monday - Back and biceps
Tuesday - Chest and triceps
Wednesday Legs and abs
Thursday - Rest
Friday - Shoulders
Saturday - Rest
Sunday - Rest
The reason we do it like that is because all those muscle groups interlink i.e. you can't work chest without triceps and vice versa.
Don't f**k about doing anything other than compound moves for your first few months. You need to build basic strength before you need to do anything like chest flies or bicep curls.
NEVER workout one muscle group more than once a week, it won't help you. The muscle will be fatigued, you won't hit it hard enough and it won't grow.
COMPOUND MOVEMENTS:
Bench press or dumbbell press,
Squat,
Military press,
Deadlift,
Barbell row.
The nutrition side is equally as important as the gym side. You will spend your life trying to learn about it.
