Explain why regular exercise is the best way to prevent flexibility issues.

regular exercise keep muscles healthy and in good shape. muscle stiffness that reduces flexibility often results from the overuse of muscle, but inactivity also weakens muscles and can make them more susceptible to injury. regular exercise keeps muscles strong and makes it less likely that simple activities will overwork or injure them.

to increase speed you need to decrease frictiona dn drag hense why sprinters wear tight track suits to keep tight against there skin to keep away from wind and decrease the amount of drag you are carrying.a swimmer will wear the tightest swim suit they can possibly fit into (i was a size 28 swim suit at meets i wore a   size 23) why? because the tighter your clothing is the less drag and negative force you have. the heavier the clothe the slower and more wind gets caught. cotton tends to hold onto alot of sweat and water making it slower then say a track suit (no idea what they are made of but they are really comfy around your answer )
