I was skipping yesterday with a weighted rope. After a while I started to get tired and start to miss. I got some red marks from being whipped on the arms when I started messing up. Why is jump rope so painful? Is there a way to get better without quitting? I don't want to quit. I stopped because I started getting red marks and it started to sting and I didn't want to get more bruises. It seemed to be good exercise but I don't want to get injured/ red marks on my arms.
