jumping makes your whole body shake and your head too~ if you jump rope too much it'll cause your brain inside to shake and thats not good for your health... like after a roller coaster, you know how your head hurts, its cause your brain had been shaking during the ride..
and for your knees and legs--excessive jumping can even harm/injure yo u
<its like running alot and damaging your knee cap cause your bones in your legs are hitting each other constantly>
i used to run every day for around 1~2 hours, sometimes even 3, thinking ill lose a lot of weight fast that way, and i stopped after i noticed my foot making a pop sound like when you pop your fingers, except it was any time i moved my leg...and it hurt too...ive stopped running for a month and now the popping has gone away, but anyways~~
i suggest anyone who does over 1,000 a day to be careful.
(haha that was a bit long... sorry)
I'll be first to call bs on the brain thing. Look at professional boxers and tons of other pro fighters and athletes. They
all skip a ton and do tons of other cardio. They're fine. Also if you have good shoes when you skip your legs should be fine.
Improper practices lead to injury just like anything else. Also obviously it's not like the average person is gonna go at it everyday
over extended periods of time. That's why it's better to have other low impact cardio exercises such as biking to supplement and
switch it up.
