Best cardio exercise

Guys...
What do you think Which is best cardio Exercise...???
share your opinion With me

Here I got an answer to this

Best? Do this workout for cardio: 20seconds of Squats, 20 seconds of pushups, 20 secs of Cobra(lay on stomach and move arms back and forward), 20seconds of jumping jacks, 20 seconds of mountain climbers. Do all of that without break and rest for 30seconds when done. Repeat 10 times.

Any cardirkout from P90x will kick your butt ~

Pretty much. P90x is legit. Also running.
Unrelated but Ab Master is my favorite because I made it my bitch. I may struggle with everything else but I rule that workout.

Dancing = pure cardio. I dance all the time!

Running, definitely running.

High intensity circuit course with minimal rest time between stages (roughly 10-15 seconds).

Running, swimming, biking, walking, jogging. ....I really should start doing more. And maybe try p90x.

running from the police

I don't believe there is a "best" cardio exercise, it's more of a personal preference. Some people may like the stair climber or running
