Too many people have been turned off of running simply by trying to start off too fast. Their bodies’ rebel and they wind up miserable, wondering why anyone would possibly want to do this to themselves. The other effect is an increased risk of injury.
It's easy to get impatient, and you may feel tempted to skip ahead in the program, but hold yourself back. Don't try to do more, even if you feel you can. If, on the other hand, you find the program too strenuous, just stretch it out. Don't feel pressured to continue faster than you're able. Repeat weeks if needed and move ahead only when you feel you're ready.
All sessions need to commence with a warm up and cool down. Stretches are manditory as well. Email me if you are unsure about the stretches to do.
On the sprint days it requires a 5 - 8min warm up at least and the same in cool down.
