Training questions (video)

[crazydog]

Hey, im a new member to the boxing fourms. I've been reading them. Just never joined one untill now. To start off, i wanted to tell you guys about myself, so that you can help me out. I've never boxed or trained how to in a gym. I have always loved the sport and so i have been training at home alittle by myself with nothing to guide me but what i learned from read and watching TV(youtube). Well i recorded a quick video of me hitting a 100lb bag. Its not the best quailty or size since i recorded it with my phone. But i hope its good enough for you guys to watch and maybe help me out with some pointers. On how i can improve or if my form is wrong. Thanks

Also, Since im a new member. I see that i cant post a video or link. The video is on youtube, so just add this after .com/watch?v=kUr108r3460
