Team Rule #1: Do not do anything detrimental to yourself.
Team Rule #2: Follow the principles of Kaizen. This is a Japanese word adopted into English referring to a philosophy focusing on continuous improvement. No matter how good we are, we can always get better.
Off Season Training - Rule of 2
No coach from a high school program (Varsity or JV) can work with more than two players from that program (Varsity, JV, or incoming Freshmen) per day using any type of equipment specific to the sport. This pertains to private instruction, camps, or club teams.
If you are unfamiliar with the rules in this situation, I recommend that you check out OSAA Rule 7 and all of it`s subsections plus OSAA Board Policy #58, including the questions and answers.
