I've honestly never heard that one...
As far as exercise goes there's an old cliché that fits; "What's good for the goose, is good for the gander." I can't think of a single exercise that a man can/should do that a woman cannot/shouldn't. We train the exact same way. They may be generally physically stronger than us but that doesn't mean we can't perform the exact same exercises as them.
I do jump rope intervals for cardio... have been doing for the better part of a year and have no ill effects. For fast jump rope, I burn about 100 cals every 10 mins. The higher your heart rate, the more calories you burn. That's basically how it works. Jump rope is usually a high intensity cardiovascular activity so it tends to have a high calorie burn.
However, others have already pointed out that it's how many calories you take in where you lose the weight. You could exercise and burn say... 300 cals extra a day but if you eat an extra 300 cals a day, you'd neither lose nor gain. Losing weight comes down to calories in vs. calories out. You have to burn more calories than you eat to lose weight. You burn calories through your BMR (basal metabolic rate, the amount of calories needed just to keep you alive; for your organs to function, your body to create new cells, etc.), your daily activity and exercise. If you add all these together you get your TDEE (total daily energy expenditure). You have to eat less than that to lose weight; -500 to -1000 cals/day to lose 1-2 lbs/week. Luckily Sparkpeople does the math for you already when calculating your Spark calorie range as long as all your info is correct; goal date, weekly calorie burn, activity level...

"Toning" is marketing muscles to women who are afraid if they pick up a barbell, they'll leave the gym looking like She-Hulk. It doesn't happen, what does happen is you get results. Lifting Barbie weights does nothing but waste time.
