What is one important consideration to make when purchasing exercise equipment?
a. how popular the equipment is among people in your age group
b. how the equipment rates among comparable products
c. the frequency in which the product is advertised
d. the size of the potential rebate offer you may receive

The correct answer is B.

When purchasing exercise equipment you need to take into consideration how the equipment rates among comparable products, this is because you need to know that what you are buying is a reliable, useful piece of equipment that you won't end up wasting your money on. If it has a good rating than chances are that it is worth spending the money on.

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 )
