Final answer:
Swimming laps provides a good cardio-respiratory workout.
Step-by-step explanation:
Swimming laps is the activity that provides a good cardio-respiratory workout. It involves using all major muscle groups, increasing heart rate, and improving lung capacity. The continuous movement of swimming helps to improve cardiovascular endurance and strength.
Practicing yoga and taking a breathing technique class may provide some cardiovascular benefits, but they are not as effective as swimming laps. These activities focus more on flexibility, balance, and relaxation.
Lifting weights, on the other hand, primarily targets muscle strength and does not have the same impact on cardio-respiratory fitness as swimming laps.
