Brotherhood if you are refering to mine, its a "knight club". We play as middleage knights, we changed now dates, now we are 1400-1450, learning traditions, culture, and most importantly, knightscraft.
We learn to use meddival wepaons, block attack, get hit and survive, horseback riding, some may try and learn craftsmanship to become a smith.
The training we have its workout, but not body-building, were strong but we can still fit in out plates. Swordsmanship (i was attending kendo for 5 months and Aiki-budo for 2 years, in Aiki-budo we also used sword) were learning to use both handned swords as well as twohandned. Less in axes and maces. Spears are also importand. In trainings we often figh against each other. Some training are also used to practice shows and prepare to upcomming tournaments (no need to practice swords if its gonna be archery turnament).
Thats all fun.
As for expances. Well armor is quite expansive... Health cre even more, horses... guess

. We also must pay for renting hall where we train, as well as workout and storage.
And income. In winter there is barelly any income. Only some duels where you are chalanged, or you chalange your self (attacker gets glory, defender money if any wins). Glory is required to recive invitation to some higher ranked tournaments, as well as get some crowd on shows. We do tournaments, each one has its own specifics and rules to witch we must agree. Some tournaments require entrance pay, some glory, others only invite. And there are shows, where we show of how life in middle ages looked like. Sometimes its just weaponary, sometimes ball, sometimes promenade, others battle recreation (biggest in Poland is yearelly 1410 Grunewald recreation, very high over 10 000 participants). Depending how you do in tournaments and how much shows you do, theres your income.
Last year i got 17000zl from tournaments and 7300zl from shows. But gave 4500zl for new armor and 2000zl for weapons. Also spend 4500zl for renting horses. "Money are not perfectly calculated" so its arround 13300zl income from this year for doing hobby. 1$ = 3.20zl i belive. So its 4156 $ + insurance and restitution witch was about 3000zl. And there is about 4000zl is spend on lost tournaments but u kno were not counting that

Bad thing is that some months you swim in "gold" and other you cant wait for a chance of getting some money.
Thats all my Brotherhood is and far more
