Help regarding Warm up exercises

Hi guys,

I am a newbie and just a beginner in guitar. I have visited threads showing "warm up exercises"..... i am able to understand the string name "E" "G" and all, but what i am confused is with 1-2-3-4 what does this mean.... how should i play ?

pls help me guys

1-2-3-4 refers to the fret #'s

i.e - 1st string: 1-2-3-4 refers to the E string (6th string) and frets 1, 2, 3, and 4.

Another way to look at it:
String 6
String E
1 - F Note
2 - F# Note
3 - G Note
4 - G# Note

The reason that you're seeing the 1-2-3-4 instead of the note names is because this is using tab notation vs standard music notation.
