If you are trying out for an Alliance team, your tryout fee will cover the cost of this session. Some teams will consider those results as part of their selection process, others will use them as a personal tool to help you reach your potential as an ultimate player.
If you are not trying out for an Alliance team, but would love to receive a professional assessment of your fitness level, you may drop in one of those sessions for a small cost of $5. Simply register online and pay your fees at the session.
