If lofted fairway woods are a challenge, the golfer probably has the low point of the swing behind the ball. Try to get your weight on your front foot at impact so you can sweep the club on the ground
If lofted woods are fine but a 3-wood is challenging, I suspect the golfer cannot create enough club head speed. It takes pretty good speed to get a straight face club airborne. So either take some lessons of exercise to create more speed or stick with more lofted clubs.
