This is a practical reference. For each flag CricMotion commonly surfaces in bowling analyses, you'll find the specific drill, the coaching cue, duration, and how to know it's working. Use it alongside your analysis report.
How to use this library
Find your root cause phase. Find your specific flag. Run that drill for 5 minutes at the start of your next net session — before any live bowling. Always address the root cause phase first.
Delivery stride drills — the most common root cause phase
Rear-knee angle at release (target 140–175°)
The most commonly flagged parameter in Indian fast bowling. A collapsing rear knee at release costs 6–10 km/h and creates significant lumbar stress.
- Drill: Single-leg landing hold. Land on your front foot in the delivery stride and hold for 3 seconds before completing the action. Focus on driving the rear knee through. 5 minutes, 20 reps.
- Cue word: "Drive through" — not "land and stop."
- How to know it's working: On re-upload, rear-knee angle moves above 140°.
Bracing time — landing to release (target 80–150ms)
- Drill: Lateral bound and stick. Bound sideways off your back foot, land on your front foot, hold for 2 seconds before completing the arm action. 5 minutes, 20 reps.
- Cue word: "Land, brace, release" — three separate beats.
Front-knee angle at release (target 160–180°)
- Drill: Forward-hinge mirror drill. Simulate delivery action in slow motion in front of a mirror. Front knee should reach full extension at the moment your arm comes over. Hold for 3 seconds. 5 minutes.
- Cue word: "Lock and lever."
"Three delivery stride drills cover 80% of the flags I see in bowling analyses: single-leg hold, lateral bound, forward hinge. They're not glamorous. But the data consistently shows they matter most. — Arjun Sir"
Impulse stride drills
Jump height at bound (target 25–45cm)
- Drill: Bound height markers. Place a target at 30cm height. Jump over it during your bound phase. 5 minutes.
- Cue word: "Up and over" during the bound.
Lead-arm reach at top of bound (target 150–180°)
- Drill: One-handed reach and land. Walk through the bound phase at quarter speed. At the peak, reach the lead arm as high as possible before landing. 5 minutes.
- Cue word: "Reach for the sky" at bound peak.
Run-up drills
Head steadiness during approach
- Drill: Book balance run-up. Balance a cricket ball on your head during the run-up. Any lateral head movement drops the ball. 5 minutes at 50% run-up speed.
- Cue word: "Eyes level, head still."
Follow-through drills
Important: Follow-through flags are almost always downstream. Before drilling follow-through, confirm the flag is not marked DOWNSTREAM. If it is, fix the delivery stride first — follow-through will often resolve automatically.
