Weight Throw Equipment

The Premium 1" Circle is the 25% thicker, denser version of the standard modular foam circle — built for programs that need a more durable, heavy-use training surface that holds its shape through high-volume throwing sessions. The laser-cut keyed foam segments interlock precisely and lay flat without adhesive or hardware, making it the most practical portable circle solution available for coaches who train throwers indoors, outdoors, and across multiple locations.

• • Premium 1" Thick Heavy-Duty Foam Construction — 25% thicker and denser than the standard modular circle, the premium foam absorbs the repeated foot pressure and lateral forces of shot put, weight throw, and hammer rotational technique without compressing flat or losing its shape through intensive daily training use
  • Laser-Cut to Regulation 2.135m Diameter — All 16 segments are precision laser-routed to form the exact 2.135-meter throwing circle required for shot put, weight throw, and hammer competition — accurate to within 0.5" diameter, meeting the dimensional standard for all three throwing events in a single circle configuration
  • 16 Keyed Interlocking Segments — Segments connect with a keyed interlocking system that locks each piece to its neighbors without tools, adhesive, or hardware — the circle assembles and disassembles in minutes by any one person and stores flat for compact transport between practice locations
  • 4-Degree Engraved Footwork Markings — Degree engravings at 0°, 90°, 180°, and 270° positions on the circle surface provide visual reference points for throwers working on rotational footwork patterns and turn mechanics — giving athletes the same kind of court markings that every other sport takes for granted
  • No-Drill Surface Installation — Circle segments lay directly on any flat surface without permanent installation — secured in place using dumbbell weights or any heavy object on two or more segments, making it fully portable and leaving no permanent marks on gymnasium floors, turf, or outdoor surfaces
  • Multi-Event Versatility — A single circle covers regulation shot put (2.135m), weight throw, and hammer training in one modular system, available in sky blue, silver/grey, or black depending on material availability — eliminating the need for separate permanent circles for each throwing discipline

Get two throwing circles out of one with the Innovative Throwing Technologies Conversion Insert. This lightweight, modular foam insert drops into your existing 2.5-meter discus circle and reduces it to a regulation 2.135-meter circle for shot put, hammer, and weight throw — so a single circle serves all your throwing events. (Note: this is an insert, not a standalone circle.)

Key features & specs:

• Converts a 2.5m discus circle down to a 2.135m shot/hammer/weight circle
• Laser-router-cut keyed foam pads lock together and fit snugly inside the discus circle
• Heavy-duty 3/4" thick foam mats; accurate to within 0.5" diameter
• 0°, 90°, 180°, and 270° footwork marks on four segments for turn placement
• Ships in sky blue, silver/grey, or black depending on availability

A cost-effective, space-saving solution for throws coaches who train multiple events in one circle. Set it into a clean, flat discus circle and press the segments together so they seat snugly, and store the pads flat and dry between sessions to keep the foam true. Remember: it's designed as an insert, not a standalone throwing surface.
