If you have a big trap with not much lip then taking a fairway wood from a fairway bunker is possible, just grip down on the club, play the ball back in your stance and make an arm swing
Juniors tend to swing harder for more distance, but what is really important is they stay in balance throughout the swing
Too many players worry about mechanical and technical things throughout their swing and never focus on balance which is the key to a stable shot, see if you are in balance by trying to hold your finish position until your ball lands
