Just to clarify, I'm certainly not discrediting leg shots as being effective. I will say that even the skinniest guy on the planet can chop away at my legs and they will eventually get tired of being kicked.
But that would mean that I allowed it to happen. My goal in a fight is to put the other guy out of commission before he can inflict enough physical harm to me that I won't be able to continue.
If someone were to kick me in the leg once, then score a point for them, they started on their game plan. If they kick me in the leg twice, well, they may have been able to sneak that one in. More than twice in a real fight situation, then I deserve the beating that I'm about to receive.
I agree that one shot leg kicks aren't a realistic solution, and that it takes time to wear down the legs, especially on someone larger than you. Your goal is the same as my goal in a fight...it all comes down to conditioning and skill on the part of both opponents, among other variable aspects. That's the beauty of fighting...it's truly unpredictable. Sometimes the outcome may be obvious, but most of the time, reaching the outcome has a few surpises in store.
Regarding the lifestyle thing Bill Mattocks is talking about...he's right and has a point...if he's fine with being larger, then that's up to him.
I can tell you this, though...I was the same way a year ago. I didn't care about losing weight. I was fine being 320+ lbs, and I wasn't going to sacrifice my pleasure of eating what I wanted just to suit what someone tells me I should eat. That all changed, though, when I discovered I was going to be a father, and I decided I wanted to be able to keep up with my girls when they get to the age that they can run around.
I started losing weight on Jan 1, and I haven't looked back. I can honestly say that I feel better all around. I wish I could say I looked better, but losing weight only gets you so far in that department...haha...
But the point is that there's a difference in how I felt then and now. My attitude still hasn't changed, because I accept who I am, and I'm proud of who I am. But I also accept that I have to change part of who I am, at least so I can provide a better life for my daughters. I've found that I'm much happier now than I was a year ago, and I attribute it greatly to losing the weight I've lost. I'm able to do more that I like to do, and I have made sacrifices that I can live with regarding food.
I'm not preaching, and I hope that's not how this post comes across...nor am I bragging...I'm just trying to play devil's advocate on both sides, I guess. Just take a look at what makes you happy, and try to decide how long it's going to make you happy. I, myself, would prefer to stay happy for as long as I possibly can.
