You know, probably rest around 94kg all winter and then I'll race at about 88kg so that drop is huge. You kind of starve yourself to get to that point but at the same time it's a very clever starvation program. A lot has changed since Rio in myself. Appearance-wise, I've grown from a boy into to a man, I think... So it's all about what's that next step to make me even faster. What I squatted before Rio, I think it was 110kg... I'm squatting 150kg now and, you know, I could go further but then you get to the question 'is it worth the injury if you get injured?' If we go to 160kg, are we kind of going up to injury territory? Or do we stay under 150kg and get more power out of it? There's a lot of calculations that the team do and obviously I work with them His body has the potential, if he did too much weights, he would just literally... It would not be okay and we know what numbers we need to get to and I think that exact science has been... we've got a formula with that and I think we just kind of refine that and trim that and try to make it better each time. [Adam Peaty] I mean I don't tend to eat meat when I'm in taper so it's kind of keeping that fat down. On those unnecessary stuff that I don't need in my body I'll strip and then I'll probably from, 6am until 6pm I'll have a 12-hour fast so, yeah, it's kind of getting into that phase where your body's burning those fats after six hours. Protein shakes, BCAAs, stuff like that is hugely, hugely important for me because, especially when we're on the go and we're at the pool most of the day we're trying to find those protein hits and as I don't eat meat it's a little bit harder to kind of get that hit. It's just all about fine-tuning, like a race car. You look at the engine; you look at the computer and you're trying to fine-tune to get those extra performance benefits and that's something we always do.
