If you are wanting to burn alot of calories really fast
jump rope is the thing you should be doing! It tones you up
crazy quick and you burn 10 calories a minute.
I love that the height can change so my husband and i can both use it.
This jump rope is very well made and strong but
also light weight so its not a pain in the butt to use.
If you are shorter and not sharing the jump rope trim the
cord and then put the little black piece back in place and you're
good to go! There's a reason all the great boxers use to jump
