Jump rope? No. No experience here, because it's not the 1800's.

Jumping is high impact and can be tough on the joints, especially if you're starting out overweight. So, maybe just start out walking, or swimming for better joint health.

Setting a 1,000,000 goal for anything is a bit extreme. That's a goal to count to 1,000,000. Have you ever even counted to 1,000,000? Nope. Neither have I. It's a recipe for failure, even before you start.

How about setting a goal for going out and walking a mile 3-5 times a week. Work up to it by increasing your distance until you can do the whole mile. If you can do that for a few months, up it to 2 miles. If you're consistiently doing 2 miles 3-5 times a week, you're going to see a huge difference in your physical fitness.

I do workouts with 3-600 jumps a session, occasionally. A million is a large number. It’s an effective way to elevate heart rate, but I’m not sure it’s the best approach for low risk entry to fitness routine. I’d advise starting with assisted press-ups, bodyweight squatting, and assisted pull-ups or rows (if you can find the equipment) and walking, increasing the intensity as your body adjusts. Jumping - and running - are higher impact and may not be the lowest risk option available to start a weight loss journey.

What are you changing in your diet? You'll be dissapointed by the amount of calories burned by an hour of cardio (especially since you're not going to be able to jump for an hour straight) and could easily eat the calories back if you arent monitoring what you eat.
