Andrea wants to improve her flexibility. she is already doing flexibility and strength-building exercises during her workout. which type of exercise would not complement andrea’s present workout very well?

biking
cross-country skiing
swimming
weightlifting

I believe the answer is: biking

When you are biking, you would put your body on a certain position for a long period of time. If this being done regularly, it would reduce the flexibility of the part of body that is used to remain fixed in a place. Rather than biking, Running is a better option for Andrea's flexibility since it moves all part of her body.
