Shelby's favorite physical activities are swimming and riding bikes. She has found that these activities help her clear her lungs the best while keeping her active and in good overall health. She knows that staying physically active is very important part of keeping up with her CF and getting a gym membership would allow her to increase her PFT scores. She knows if she works hard that as she gets older her lung function won't decrease. Shelby used her recreation grant to get a gym membership.
