I joined gym in when I was 18 years old but due to my tight schedule I couldn't continue the intense workout session in the gym.
Now, after few years, I am once again trying to re-start my gym work outs. Based on my earlier experience, I have noticed that calf muscles, fore arm strength effect almost every workout. So I want to be better prepared this time.
I am regularly doing stretching exercises, push ups (for chest & biceps), Chair Dips (for triceps), squats (for thighs).
So, my question is What is correct way to prepare your body for gym workouts in terms of exercises and time?

As per the question of what I am trying to achieve? I am trying to gain some weights, then after I get the desired mass, I am planning on concentrating on strength.
