Champro Cast Iron Shot Put

The Champro Cast Iron Shot Put (4 kg / 8.8 lb, Style TSC4K) is a solid cast iron throwing implement sized to the metric competition standard for high school girls' track and field. The 4 kg weight is the official competition specification used by high school women's programs in states and associations that follow metric weight regulations under NFHS and international guidelines — as opposed to the imperial 12 lb weight used in some other state associations. The symmetrically balanced cast iron construction provides a consistent surface texture and a predictable release from the throwing circle, making it suitable for both practice sessions and sanctioned competition on concrete and track surfaces. It is used by high school women's throwers, club athletes training toward collegiate and international standards, and coaches managing programs that compete under metric weight rules. At 4 kg, this implement sits at the official women's competition weight for high school, collegiate women, and international-level throwing — making it relevant from the high school level through elite competition. The cast iron material holds up well through repeated daily practice throws on concrete and synthetic surfaces, and the familiar heft of 4 kg helps athletes develop the rotational strength and release mechanics needed for advancement. As with all cast iron implements, use on gravel or stone surfaces is not recommended, as the material will chip over time when thrown onto stone. The high-visibility blue color of the Champro shot put assists with tracking during outdoor practice. Key Features:
