What batsmen like me do for fitness is often a bit different to what bowlers like Jimmy Anderson or Stuart Broad do but everyone in the squad has a big focus on core strength. It is really important for batting, bowling and fielding. You need a strong core and spine so your movement isn't restricted out there.
We think it is a really important part of your journey, as an international player, that you come in and you want it to feel like it's the pinnacle of the game. That you want to come back into that environment. You don't want to think, 'Well, I'd much prefer playing for Sussex,' or your county.
