Injury and workload
Overuse injuries in bowling often come from high volumes without enough recovery. Many club and amateur bowlers exceed sensible weekly and monthly limits without realising it.
Cricket Sleeve helps you see not only how you are bowling, but how much. Track deliveries per session and across the week, and get straightforward guidance when you are approaching commonly recommended limits for adult bowlers.
Better technique plus smarter volume means more bowling and fewer setbacks.
