I follow what you guys are saying. I agree with health maintenance. I believe the more modern way is to do weight training. I talk mainly on fighting because this is MA forum. I spend half of my exercise time on weight/resistance training. MA exercise break down the body, weight training rebuild the body. As people get older and still doing intense MA, injury is a lifestyle. Weight training fixes most of my injuries. It is more efficient and make you stronger.
I said it many times already, I injured my back in the 80s and for a while, I cannot even stand for 2 minutes without tingling going down my legs all the way to the toes. Doctor exhausted all different treatments, they finally put me on rehab with weights actually doing in the gym. That literally saved my life.
There is some magic about doing weights IN THE CORRECT WAY( you really need to learn how to do it, not just pushing and pushing, that can hurt more). Based on result, look at the top athletes today, they stay on top to the age people would not dream of just 30 years ago. It's all from weight rehab. If you just keep up with the weight without trying to stay on top of the game, I bet you can last as long as you live. It is so much more efficient and to the point. Time is money in the modern world. BUT, you need to get professional help to learn before you venture out on your own doing weights. It can be dangerous if not doing right.
As I said before many times, if I have to choose between MA and weight training, it's a no brainer, I drop the MA in a heart beat. I am always very adventurous, I don't believe to just blindly follow what is established. I always stop and think and question the validity. I do not defend the existing, instead I always find better ways to achieve the goal. Believe it or not, I usually find better ways to achieve the goal.
