you don't, adding weight is how you get injuries. if you're ok with looking like a spass run while pulling a sled or something

You want more resistance when running? Run up hills!

What's wrong with wearing more weight ? Why hasn't anyone invented weighted shirts ? Like what goku and piccolo wear for training?

>>39005140
Is it ok to work your lower abs with those r-right?

Not OP but can anyone explain why ankle weights fuck up your joints?
Why does weight lifting not fuck up your joints? Isn't running with ankle weights just lifting weight with your feet?

>puts weight in momentum directly against or near a vulnerable repeatedly.
>adds to the impact when you brace against the ground
These are both bad in high repetition excercises. that's why pulling is better than carrying. Have if you really wanna add weight a backpack is better
