Are there any restrictions that would prevent me from jumping?
We evaluate each student on an individual basis. In general, you should be in reasonably good physical shape; this is a sport after all. Problems may arise where a prospect is too heavy (over ~220lbs) or if they have medical conditions that may impair them during the activity. Very few people have medical or physical conditions which actually preclude jumping.
If you have a question, ask your doctor. You may be surprised at the relatively few physical constraints involved.
