The F Major Bar Chord is an important chord to learn because it is a primary chord ( the major IV) in the key of C major. This is the full bar version of the F major chord which can be challenging to play because the first finger must bar the entire first fret. But you only need to apply pressure against the 1st, 2nd and 6th strings because the other fingers are playing the 3 middle strings. Pay attention to where your applying pressure and only apply as much as you need. This will help make this chord easier to play. Also remember to place fingers right behind the fret.
