you dont get to just randomly pick a country and off you go. you must have some link to that country preferably being a citizen athough in some cases if grandparents were citizens for example you may be eligible to represent that country I’d assume they’re doing the The Philadelphia Aj Brown Jt Realmuto Jalen Hurts And Bryce Harper Abbey Road Signatures Shirt so you should to go to store and get this same training as if they were going to Tokyo this year, although their coaches and trainers might allow them to take off a month or so. Some of them may be asking themselves if they can afford to continue training for another year. They’re the athletes who never see themselves on a Wheaties box and whose sports are never mentioned in non-Olympic years even on ESPN, Depends significantly on the sport and nation. Certain nations have a focus more so on high volume repetitive based training following East German or Soviet style, where-as some others focus more on scientific quality based training and as such have lower volumes. Some countries training to be an Olympic athlete is a hobby that athletes do before or after their work, where-as some other nations it is a full-time professional paid job. As Roberto Blanda answer suggests for rowing in his country they trained 5–7 hours a day, and other endurance-based sports like swimming and cycling have similar hours of training a day. Where-as some other power or speed sports like sprinters and weight-lifters want to be fresh before each session so often do only a few hours of training a day, sometimes with rest days between and might combine this with gym session later in the day. Team sports such as basketball or football often have a skill session of 2-3 or so hours once a day 4–5 times week, and then a seperate strength & conditioning session done 3–4 times a week. Some Olympics teams I’ve worked with are finished all their days training by 10 am, where-as some others have gone from morning until later night with after dinner video analysis and coach discussion sessions. So it varies considerably.
