Just got my Jan/Feb 2023 of AARP and the main story is about Heart Disease. In the article it talks about: "A great sport for your heart?". Those listed are: tennis and badminton cutting fatal CVD by 59%, followed by swimming and aerobics, 41% and 36% respectively, Distance running less effective. The article doesn't mention frequency of exercise or duration and whether or not it was coupled with other forms of exercises. I wonder what effects jump roping has on lowering risk. Maybe Dan or Brandon can chime in if they're aware of any studies.
