Jumping rope is an excellent
workout as it can be designed for cardio training or
modified for interval training and can burn a lot of calories
in a short timeframe as it involves both the upper and lower
body. Jump rope workouts also help to build bone density
and coordination. One can modify the step pace, jump with
both feet or alternate feet, move forward and backwards,
reverse the direction the rope moves in, do an occasional
double under (rope passes underneath feet twice with each
jump), etc. Use your wrists to rotate the jump rope and
be careful about sharp sidewards movements as they can lead to
painful injuries (know this from personal experience).
While the jump rope does need a clear path under your feet to
continue, it isn't necessary to jump high. It just takes
a little practice to get used to the jumping movement. I
prefer to use speed ropes but there are a variety of
choices available. Just make sure you have the proper
length for your height. To check this, when jumping note
that the rope should just barely touch the surface under your
feet.
