Mix bursts of cardio into your strength training for a metabolism-boosting workout that will tone you from head to toe! For day 16 of the Bikini Body Countdown, we've created a mashup workout with a 1:1 ratio of cardio to strength training. The cardio portion is jumping rope, but don't worry, you won't have to do all those minutes back to back. The jumping is mixed with targeted strength-training moves. Don't have a jump rope? Fake it. Seriously, you might feel a little silly, but jumping in place for a minute is killer (and easier than dodging a rotating rope).
