The new US Soccer Curriculum outlines the importance of training versus playing matches. Albeit matches are important, quality training should consume 75% of the time on the field during the week. So depending on age group, 3-4 sessions per week with a match on the weekend.
The importance of a planned training session is imperative to the overall development of your players. Not only that, it makes you organized and passionate about your job as a soccer coach. Post-planning after a session allows you to takes notes and work on certain issues that arose during that session. This topic of post-planning can be found here.
Write out a lesson plan after your last training session. This will give you a vision and help structure the next session in your head. Extra time on the "day of" training, is few and far between. A coach can find themselves scrambling on the fly once they arrive at the field.
Show up early. Get to the field before your players, for several reasons. A successful manager is at work before their staff or players. This gives you time to setup the field accordingly and reminds the players that you are there for a reason. It advances your voice into a more reliable light.
