Training for soccer it is important for me to get a lot of Cardio work in before the season. The drills I usually do involve jogs mixed in with a few sprints. This is much better for you than just jogging long distances at the same speed. Long distance running can wear on the joints and has been know to lead to tendonitis. Plus I like to incorporate variety in my routine so it dosnt become boring.
Exercise #1 Start at a football or soccer field at one corner facing the short side
* Lightly jog two laps around the field as a warm up and then get a good stretch*
Lap 1- SPRINT the first short side, then JOG the long side, JOG the short side, JOG the long side until you end up where you started.
Lap 2- SPRINT the first short side, then JOG the long side, SPRINT the short side, JOG the long side
Lap 3- JOG the short side, SPRINT the long side, JOG the short side, JOG the long side.
Lap 4- JOG-the short side, SPRINT the long side, JOG the short side, SPRINT the long side.
Congratulations you have just finished one circuit!!
Try to see how many circuits you can do and then try to improve a little more each day. If you feel like you cant do anymore you can even rest by walking one of the sides and include that in your routine. The point is to push yourself and give your maximum effort so that everyday your are improving.
