Just finished swimming a race from Alcatraz to shore, it's just the best high. I do tons of endurance sports, but swimming is the most reliable in yielding that euphoric feeling. I think it's due to it being essentially forced mindfulness meditation. Though you could swim with music, I don't and that means it's just my thoughts for 30-60 min (watch the thoughts, can't do anything about them right now). I'm forced to…
cycling: the most enjoyment of scenery, 26km (how I do per day) gives you a lot of different views; mountain, river, road, smell of air along the ways. These are also good for brain.
basketball: it just nicely exercises agility, muscle memory (imagine you nail it 10/10 shooting continually, how nice the muscle is!), reactivity, quick decision making as a team.
table tennis: it is incredible how you can control the small ball in very fast interaction, in very small area (table). Little skills you gain from this is mind-blowing to me.
I play a lot of other sports, I'm very satisfied what my body can do, and breaking current limit is also fun.
