Most shot put errors live in the footwork or the power position, not in the release, and both of those are fully drillable without a shot in your hand. A 4 to 6 kg medicine ball reproduces the drive and extension of a standing throw closely enough to matter; a chalk circle on grass reproduces the ring closely enough to matter. Neither replaces the exact feel of a 12 lb (5.44 kg) implement leaving your hand, so treat these as the 80% you can build anywhere and save real-shot sessions for the last 20%. This is also cheaper and safer than it sounds, a medicine ball and a piece of chalk cost a fraction of a legal shot and a ring, which is exactly why so many programs lean on substitute work between real throwing sessions. Below is the full substitute-drill table with reps and what each one is actually correcting.
The glide or the spin is a balance and rhythm problem before it is a strength problem, and a chalk circle drawn on grass lets you drill it at full speed with zero risk. Do both directions, both feet, before you ever add a ball to your hand. Most young throwers skip straight to loaded reps and never fix a footwork fault that shows up on every single throw, because the ball's weight masks the exact balance error the empty-circle work would have exposed.
A 4 to 6 kg med ball thrown from a static power position trains the same leg drive and trunk extension as a standing throw, just without the exact weight or shape of a shot. Keep these sets short, 3 to 6 reps, and maximal in intent. This is strength-speed work, so junk volume just teaches a tired, sloppy pattern, and a tired pattern is worth less on video than no rep at all.
A resistance band around the throwing hand, or a lighter ball thrown for speed, lets you feel the full extension and finish of a release without the shot's inertia fighting you the whole way. Use these to clean up the finish, then confirm the pattern held once you add the real implement back in. The honest caveat here is that band work trains the path but not the timing, so it is a complement to real-ball reps, not a replacement for them.
Drills only matter if they show up on the ring. Once a week, film a real throw, AI compares footwork, power position, and release angle to the home work. If the patterns are clean, distance follows.

None of these fully replace the ring, but each isolates one piece of the put you can actually correct on video.
| Substitute implement | Drill | Sets x reps | What it corrects |
|---|---|---|---|
| Chalk circle, no ball | Glide or spin footwork | 8-10 reps per direction | Ring balance and rhythm |
| Medicine ball (4-6 kg) | Power-position drive | 3 x 6 | Leg drive and trunk extension |
| Medicine ball (2-3 kg) | One-hand put | 3 x 6 | Release path and wrist flick |
| Resistance band | Standing release | 3 x 8 | Full extension and follow-through |
| Underweight ball (~3 kg) | Standing speed throw | 3 x 8 | Rate of force development at speed |
| Overweight ball (~7-8 kg) | Standing strength throw | 3 x 6 | Strength through the power position |
| Broomstick or PVC pipe | Glide walk-through, no ball | 4 x 5 | Footwork sequencing with zero load |
| Wall power-position hold | Isometric hold | 3 x 20-30 sec | Positional strength at the block |
