Any good exersises to get in shape for high school football

Sure there are a lot of them. Conditioning is very important so start with running but here a couple more:
- 'Suicides' - Sprint to the 10 yard line and back to the goal line, then to the 20 yard line and back to the goal line, then to the 30, 40 and finally the 50 and back. Take a one minute break and do it again. This is great for speed, acceleration, and agility.
- 'Up-downs' - High step your feet in place (like you're running up imaginary steps) and then drop to the ground and do a push-up every 10 seconds. See how long you can go and try to improve.

Of course everyone wants to be bigger, faster and stronger then their opponents. But the key is knowing how to get that way. The two excercises above are good but are actually not going to increase your speed a whole lot if any. Suicides and down-ups are for conditioning. Not muscle building.

It depends on what you're looking to do. If you're already fast then focus on areas such as strenth, conditioning and agility. If you're already really strong focus on speed and agility.

What position are you or are you hoping to be?

P.S. I was cornerback and wide receiver so I focused a lot on my speed and agility. If you're a lineman focus on strength and agility. Quarterback should focus on agility and QB fundamentals.

Keep me posted!
