Berserk Cyberdeck with Hero Landing helps a little in leveling Athletics, find some mobs, activate Berserk, double jump straight up(or from a high spot if it's near those mobs)so that Hero Landing activates, kill the mobs and see what you get; you can get anywhere from 80 points to i think i saw 670 or 970 once in my 271 hours of gameplay and that was on my male V char, different save.
Also keep in mind that the landing has to hit/damage at least one mob for the Landing to count and get the points, sometimes it'll glitch and drop just a few points in brawler and no athletics and sometimes it won't...... so yeah, it's broken.
Just to put it in perspective: my first char, male V had 18 Body; i played for 160-170 hours with that char; completely cleaned up the map of every event, Athletics lvl? 13......and i farmed the athletics as much as i could.
