Whatever you do for cardio today, double the time to burn twice the amount of calories. You can do it!

what can i do for cardio if i pulled the big muscles in my calf?

Hey, Cindym264… If you have pulled calf muscles, you can always go into a half squat and just do puch like you are hittin a punchin bag. Your arms are above your heart and it will get your HR upwothout hurting your legs. Hope it works Cece

O! I did it! And I’m not feeling well now. A headache, the body soften and disoriented. Want to fall and sleep anywhere.

Just did your double-the-time cardio challenge on the treadmill — I really hate running!! cardio is NOT FUN!! love ya anyway!

Thanks for the challenge… 90 minutes on the elliptical was a great experience. 10 miles and almost 2000 calories.

Thanks for this.

Alright, so I ran just over 6 miles in the morning, and took a kickboxing and strength class in the evening! Thanks for the challenge! And I signed up for a 5 mile run in July!
