Ok. I'm thinking about buying a "boxing station". This is sold at Dicks Sporting Goods, and you can hang a heavy bag on one spot, speedbag on another spot, and then a double end striking bag. In addition, it has a spot where you can do leg raises, pull ups, dips, and push ups. This seem like a good idea? Anyone have any pros or cons about these types of bag holders?? My real question is about which type of heavy bag to get. Is there any real advantage or disadvantage to a Muay Thai bag over a standard heavy bag?? As far as bags go, any problems with a vinyl bag?? I'm not seeing many Muay Thai bags that are leather. I&I's are vinyl. What about canvas? Recomendations as far as brands or weights??
