Jump roping is one of my favorite exercises. It is very intense, so it burns calories quickly, while improving your quickness and agility. They’re very inexpensive, so pretty much anyone can get access, even if you don’t belong to a gym, or they don’t have one. Also, jump ropes are so small and lightweight that you can easily throw it in a suitcase or gym bag, or hide it in your closet when you have guests.
