I've been told that 15 minutes twice a week at your target heart rate (THR) is enough for cardio training. Build up to that slowly. Be sure to take a warm up period and a cool down period.
The objective is to work just under the sweat threshold at at the target rate. Your THR is determined by your height/weight/age. Mine is 115.
Don't do this stuff alone. Get and use qualified advice.
