Irish Olympic swimmer Jack McMillan: I need to eat around 4,000-4,500 calories a day

I get up around 8am to do training which lasts around two hours, then I get back and eat my breakfast which helps me recover fuels me for the day ahead.

For breakfast, I eat a bowl of cereal, bowl of porridge with banana, three or four eggs and bacon. I also try to take a lot of water in throughout the day. I need to eat around 4,000-4,500 calories a day, which includes my macro and micronutrients.

For lunch I will maybe have chicken, rice and spinach and a smoothie including mixed berries and banana. I have a snack before afternoon training which might be a bagel with ham or peanut butter, along with a few rice cakes. After afternoon training, I'll have a protein bar.

Pasta and chicken with broccoli - I would also have a mass 'gainer' shake to finish off any calories left in my daily allocation.

I am a university student, so we have been working from home and having our lectures online. This has actually helped me, as I can get on with the lectures at my own pace and organise my university work better to fit in with my training.

My best lockdown meal would have to be my home-made burgers which I wouldn't normally cook when in training. I enjoy cooking and having some more flexible time has allowed me to experiment with different foods.

My weekend treat is a takeaway from a pizza or Chinese restaurant.

I am still getting up early enough in the day to do my training which keeps me in a routine, which is what I need to be productive. It is important for me to have a routine I can stick to. I have kept my mind busy by working on different projects which has helped me mentally.

I was lucky enough to get gym equipment from SiNi which helped me continue with my strength training throughout the lockdowns. I have also been on the bike, going out for cycles or jumping on the spin bike in my garage if the weather wasn't too good. This helped me maintain my fitness and aerobic capacity.

I relax by watching Netflix or playing Xbox with my mates - it helps me chill out from my workouts throughout the day. I also like going to the cinema or into town shopping with my girlfriend.

My favourite drink would have to be Jack Daniel's and Coke or a beer. When I have free time, I like going to the pub with my mates.

I am currently reading David Goggins's Can't Hurt Me. I would recommend it to anyone who wants to learn about mental toughness.

Money Heist is a very good series.

I have learnt that I can be resilient, even when I can't train properly, and with a global pandemic going on, I can still focus on my goals.

Probably five out of 10. Looking back, I don't think it was that bad as I was able to spend more time with my family. I just embraced the time we had together.

Now, I miss the free time I used to have, as I am back into a strict routine and don't have as much time to play Xbox or to watch Netflix... At the beginning, I missed seeing friends, going out and going places.

I can't wait to go abroad to compete again and attend training camps away in the sun. I miss doing these things.

I haven't really had any. I have maintained a good healthy lifestyle throughout.

No, not really; I am still able to concentrate on my goals that I want to achieve and they have just become clearer than before. That it has pushed me to keep training hard.

I have started reading more as I have had more time to sit down with a book. This has really helped take my mind away from training and just relax.

I think that everyone will be more aware of their hygiene and the hygiene of others. Everyone will hopefully take care of their body and lifestyle. Hopefully, these things will carry over after this is over.

I will take care of myself even more. I think living in this pandemic has shown me that keeping active and healthy has improved my mental health, as when I don't exercise, I feel it makes me lazy in every aspect of my life.
