Yes, there are exercises you can do to improve your stamina. To build up your endurance and better your cardiovascular health, try these three workouts:
Interval training: Interval training alternates between periods of high-intensity activity and low-intensity activity or rest. This type of workout challenges your heart and lungs while helping you build up your stamina. A typical interval training workout might involve running at a fast pace for one minute followed by one minute of walking or slow jogging.
Fartlek training: Fartlek is a type of interval training that combines periods of high-intensity activity with periods of lower-intensity activity. The name comes from the Swedish word for speed play. This type of workout is flexible and can be adapted to any fitness level. For example, you might sprint for 30 seconds, then jog for two minutes, then walk for one minute before repeating the cycle.
Hill training: Hill training involves running orwalking uphill to improve leg strength and increase lung capacity. This type of workout can be done outdoors on a hill or incline or indoors on a treadmill set at an incline. Start slowly with a low incline and gradually increase the angle as you get stronger.
