Question for Coach Rippetoe about sprints

[Strength123]

I saw on your YouTube channel you dont reccomend cardio for novices. If i was to add cardio now that i am an intermediate lifter what is my best option? Sprints, circuit training, kettlebell swings, jump rope. If sprints, how many days a week and how long should the sprints total distance be.

Thank you

[Mark Rippetoe]

Prowler is the preferred conditioning tool for those lifters who can productively use conditioning.
