1. Combine strength days with cardio days.
It’s a simple equation: the more muscle you can get working, the more it will challenge your heart and your cardiovascular system. Instead of building cardio-only workouts (the pitfall that’ll prevent you from building endurance) make sure to weave strength days into your training. “Most people reserve one day for strength and another day for cardio.
