Here is the welcoming on their webpage regarding female wrestlers:

Because we are still building the amount of female wrestlers at INWTC , it is recommended that each girl bring a partner to practice. We do not always have girls that match up in age, weight, or skill level, and so it always helps to bring another girl for a workout partner. Our philosophy at INWTC is that we will not force any male or female athlete to have to practice with another wrestler they are not comfortable with. This can be for a multitude of reasons that can including skill level, size, and gender. Everyone will be treated equally in the wrestling room and at tournaments, and our current female athletes continue to have success at the state and national level. As womens wrestling grows and evolves, so will INWTC in accommodating the number of girls we have on our team, and we look forward to building our numbers for the future.

In other words come practice but bring your own partner to practice the bulldog with because your not practicing with any boys.
