Hi Gmail.
My experience has been that jumping rope has less impact on my joints than running. But of course, if there is an unresolved injury skipping/jumping rope could make it feel worse.
An interesting thing about skipping rope that I read is that it is almost impossible to do with bad form. It's kind of a self correcting exercise...if you fail to do it correctly, the rope stops you from going further.
I'm with Nelie...I think you may need to just try it to see how it suits you.
May I also suggest that you do not do this every day. Like everything else you have to build up your endurance for the activity...perhaps it does resemble running in that way. I would not skip rope every day for weeks on end. I have found it useful to switch into my routine about twice a week.
The other thing to consider is that you probably should not set your goal of skipping rope for the same amount of time that you would spend on an elliptical or a speed walk/slow run on the treadmill. Obviously the faster you turn the rope the harder you will work so there is a little bit of variance in effort. But in my experience...skipping rope was just always an HIIT exercise for me by default. Not a bad thing...smart use of your time but it is a different experience so having the right mind set will be important.
Now...your original question, are you too heavy to skip rope? Again, this is going to be your personal experience and I think how your weight is distributed. While working with DH (which only happened like three times ever...) I handed him a jump rope and told him to get busy. Poor guy. He tried. Really really tried. But what got him was back pain after the first five minutes. He carries his weight in his tummy and as a result, it was too much stress on his lower back.
If you decide to incorporate it do it slowly. Work up to it just as you would if you were to begin running. Make certain to stretch the calves, flex the ankles well, also maybe think about massaging the plantar fascia under your feet.
Also know that you should never skip or jump on a surface that doesn't give. Concrete? Don't even THINK about it. Best surface is a wood floor, think indoor basketball court. A super cushy surface is just as bad because it absorbs too much of the impact of your feet/legs and you don't have the rebound necessary for your jumps. This also could lead to injury.
I have seen jump rope mats sold through various places online but I don't have experience with them to offer you suggestions.
Best of luck with it. And, if you don't include it now consider it as you continue your fitness experience later on. It really is a great way to do cardiovascular training, agility training, the impact is awesome for encouraging the healthy remodeling process of our bones. And finally the real reason I do it, my inner eight year old insists on coming out to play every once in a while.
Oh, and with regard to jumping/skipping style. There are many methods just as Kaplods pointed out. Usually, I am lifting both feet off the ground at the same time but the feet just barely rise from the floor. There is just enough clearance for the rope to get between the floor and my shoes. You may want to look into the different methods and try them out. I did find the book "JumpRope Training" by Buddy Lee to be helpful. Check if the library has it first. And one final tip...Speed...it's all in the wrist.
