Many competitive swimmers practice in loose-fitting, baggy swimsuits called drag suits. In 1–2 sentences, explain how, in terms of the forces acting on a swimmer, wearing a drag suit differs from wearing a tight-fitting racing suit, and why practicing in a drag suit can make a swimmer stronger. And write like a fifth grader

Wearing a drag suit makes it harder for swimmers to move through the water because it creates more resistance or "drag." This extra challenge helps them build stronger muscles and swim faster when they switch to a tight-fitting racing suit.
