Is hitting the heavy bag everyday for the same rounds (sometimes up it some) for say, a year, get you stronger or will you eventually peak and then hitting the heavy bag just keeps your strength.

I know it's suppose to increase your punching power (and many other things, but i'm focusing on power), so saying you hit harder and then you keep hitting it as hard as you can, progressively you'll increase your punching power for a whole year?

Just curious, might be dumb question.

You get a bigger heavy bag when it starts swinging too much if you want to keep developing your power.

You said it yourself.. Dumb question ^_^

Of course it does!
