There are some great tips there from scarcev and BBB, well done guys.
Scarcev makes some excellent points and one I would particularly like to highlight is - Make it Fun and Make it Flow. If training is fun and the players are not standing around for long periods of the session, you've already made a great start as a coach. Don't forget to have fun yourself too!
As far as coaching practices go there are more than enough ideas on YouTube for coaches and players of all abilities and experiences. I say 'ideas' because you can modify virtually any training activity to make it work for you and your team. YouTube is particularly useful because you get to visualize the practice session. If you are a Facebook or Twitter user there are also heaps of groups to join with coaching advice and training ideas. The Interweb also has many great websites with vast libraries of training activities. These mostly come with a subscription fee though but are great tools.
I get the impression you are a little hesitant about getting the coaching gig. I assure you there is no need to be. Before you know it you'll see things you've worked on in training become a habit to the players and it'll all be worth it. Also, don't worry about whether you will be a 'successful' coach or not. I've seen many coaches win trophies over the years but the following season they need to rebuild their team because the players leave. I've learned that these are not 'successful' coaches. In my opinion, successful coaches are simply the ones who progress the players ability whilst getting the players to come back season after season. Make that your focus and you won't go too far wrong.
I wish you every success and I'll certainly be interested in seeing how you and your team develop.
