Drew is a fit and successful athlete, but Drew's brain is weak, it's not fit. He wants to do better but doesn't know how until Deena's brain comes along. She explains that reading is the weightlifting and aerobics training for the brain. She tells him if he reads a lot he will have a big buff brain. Drew starts reading a lot and his brain gets fitter, stronger, buffer. With his new big buff brain Drew wins lots of medals and trophies!
