You run on your toes with your weight forward, go up the hill as fast as you can make yourself go, because hills hurt the same whether you are sprinting or jogging up them, and the faster you go the less time you're on the hill. When going down a hill take long strides and let gravity take you, you can get a good lead on those around you by using hills. It also depends on how steep the hill is, if its not that steep then i wouldn't sprint but if it is steep then sprint it because it doesn't hurt any more then if you jog it. So don't just go out and sprint every little hill you'll get way to tired.
Run around a track or jog up a hill or sprint across a field.
Sprint is not an adjective it is a verb Sprint can also be a noun.
Hollow sprints include a period of jogging or rests between two sprints, acceleration sprinting starts from a rolling start, [eg; you start of slow and gradually gain speed] moves to jogging and then sprinting at full power. Hill sprinting helps to develop power and acceleration by running uphill [the hill should be slight, not too steep]

sprint
You cannot put an unlocked device on Sprint. You also cannot unlock a Sprint phone. I use the term "Sprint on Sprint only" meaning Sprint phones for sprint service, and no one else may use Sprint phones. **** Not true. You can unlock sprint phones and use them with other carriers.
you call sprint and you make a contract with them
What "are" sprint phones? Sprint is a phone company like T-Mobile or AT&T the phones that they use have the sprint logo on them.
Yes, but you can also have a Motorola phone but yes in order to have sprint service you need a sprint phone
Sprint stores will almost always be carrying sprint mobile phones. The best way to get an answer on that is to call the Sprint company and talk to them.
