Incorporating cardio into a strength routine can be done effectively by scheduling workouts to include both types of exercise. One approach is to perform cardiovascular exercises on separate days or after strength training to prevent fatigue from hindering performance. Alternatively, integrating circuit training, which combines strength and cardio elements, can maintain heart rate and maximize workout efficiency. Including short bouts of high-intensity interval training (HIIT) can also enhance cardiovascular fitness while promoting muscle endurance. This creates a balanced routine that supports overall fitness goals.
