in recent discission roshan mahanama stated his idea about sports fitness like this.
About fitness – some people say “you must run 2km”. I don’t accept that 2km running. Players need to understand and do their own fitness work. Don’t wait for the trainer or someone else to tell you.
These kids need to do it because they want to. When we played, nobody was there to help us. But I remember running on roads and in paddy fields. That’s what we knew. But now you all have trainers to guide you.
Another thing – discipline in cricket is important. One part of discipline is technique. When you move forward in the game, technical issues come. To fix that, you must spend time on your game, work hard, and dedicate yourself to improve those skills
