I'll give you my costs in a week

Training
Our boxinggym is really cheap. The costs are 5 euro's a week (that's about 4 dollars), no matter if you only come once or if you come everyday. The week runs from monday to friday. If you don't come for a week, you don't have to pay anything. The runningtraining on sunday in the dunes is free of charge. The fee is for any kind of training (recreation or fight)

Travel
I train three days a week at the gym which is a 8 km drive from my work. So in a week it probably costs me about 7 or 8 euro's (gascosts here (netherlands) are about 1,5 euro per liter )

Other
the annual fee to our national bond is 20 euro (about 16 dollars) and a matchlicence is 17,5 euro (about 14 dollars) which you only have to pay once. At our gym we don't have to pay for matches, the gym does that. Also travel to the matches is organized, that means, we ride along with the trainers so we arrive rested. Gloves, mathcclothes (exept your own sneakers) and headgear are also provided by the gym.

Boxinggloves (leather) for training (we normaly use 14oz) are about 70 euro (56 dollars) and a mouthpeace is 3 euro (2,5 dollars). A custom made mouthpeace which i have, costed 220 euro's (176 dollars). we use normal trainingtrousers and shirts available anywhere. For sparring we use 18oz gloves which are also provided by the gym.

offcourse everyone is free to buy there own equipment to use insteed of those provided by the gym, but just a few do so.

Well, those are my costs.
