It kinda depends on the country I think. For Greece, I think it's not cheap at all. You can find an annual gym subscription for 80 euros.50 a month isnt at all bad for cross fit, its commonly 3 or 4 times that,
it is however still a lot of money for what you get, whovj can be easily replicated at home for an out lay of a few dollars
gyms arnt general crowded, except for january, well not for box j7mping and doing pull ups anyway, the
Mostly I would be interesting to know what boxing traininng involves. I kinda feel it's only jumping ropes and punches. I'd need push ups, pull ups, burpees, some kettlebell exercises..
Oh and a stupid thing to mention.. I really admire my crossfit trainer (Actually it's called functional training but It's very very similar to crossfit). He taught me how to perform all these exercises in the correct way. I'd feel like I kinda betray him if I left his class.
