Practice Detail

Full Practice sessions will usually last between 1 hour and 2 hours.  There will first be a 5-minute minute warm-up, which includes dynamic stretching.  Depending on the day, there may be plyometric work immediately after the warm-up, to help build explosiveness.  Any agility and/or mobility training will follow the warm-up session.  The practice will then move into specific throws technique work, with or without throwing, using selected drills.  Some film analysis will be included. 
   Sessions may either be one-on-one (one athlete with the coach), a group training when available, or an open throwing session with limited drill work.



USATF Membership

All athletes, upon arrival on their first day of practice,will be required to submit a signed liability waiver and proof of USATF membership (USA Track and Field).  Click on the links below for the Impact liability waiver form and a direct link to USATF's website for membership.  Be sure to be dressed for practice, which includes proper workout clothing, running shoes, towel, and water bottle, if needed.  Throwing shoes will not be necessary for beginners at first, but will eventually be needed as the athlete progresses in their technique, and the drills become more event-specific.  Throwing shoes are available online and at specialty stores, but not at regular chain sporting goods stores.  Coach Kajtsa can help in obtaining throwing shoes, if necessary.  Contact the coach for details
