For me when I started I had never even jumped rope before. I am also on the heavier side. Make sure you don’t go too hard at first your feet, ankles and knees are likely not ready for it. Start small. Get your technique down first. Once you are comfortable just jumping with the rope then you can do internals, like 20 seconds on 10 seconds rest for 8 rounds and repeat that 3 times. As you get better you can then add more sets to that, one thing that really helped me get started was heavier ropes. It helped me get the rhythm down and it also helps boost my workouts since they were predominantly technique focused. If you have the means I would get a few heavier ropes. If not that is fine as well. A great resource for workouts and tips are the jump rope dudes and crossrope on youtube. They have follow along beginner workouts that can get you started on the right track today!
