Cardio Warm ups?

[ShouBox]

Are there warm ups/stretches I should be doing before cardio training?

If there are, would the types of warm ups change from diffrent cardio activities? (run, skip, swim)

You should always warm up!

I would suggest beginning at a low rate and gradually increase the pace. follow that with some dynamic stretching.

something like this, if you're mainly running.
