Why a 15 minute cardio timer works

  • Row, bike, run or skip
  • Set the pace, not the distance
  • Full-screen digits across the room

Timed cardio removes the temptation to slow down and still call it done. Set the block, hold the effort, and ignore whatever the machine claims about distance.

Questions people ask

Is 15 minutes of cardio worth doing?

Yes. Fifteen minutes at a moderate to hard effort delivers most of the cardiovascular benefit of a longer easy session, and it is far more likely to happen on a busy day.

Do I need to warm up for a 15 minute session?

Yes, inside the block. Two to three minutes of easy movement first still leaves eleven or twelve minutes of real work.

Do I need equipment for the 15 minute cardio timer?

No. Everything in the plan above works with bodyweight and a patch of floor. Add kit if you have it, but the session should not depend on it.
