Endurance of the heart and muscles and core body strength.
This is a condition where there is a lack of mineral that is needed for normal metabolism and nutrition. The body needs normal amount of minerals for the body to function at its best.

VO2 Max is the maximum about of oxygen that is needed by a body, or that the body can take in. By increasing this number, you can run, swim, and do other activities faster.
Interval workouts (assuming you're talking about HIIT) improves the anaerobic system in the body, which means that it improves your body's ability to function without enough oxygen.
During high endurance activities, the primary muscles used are predominantly slow-twitch muscle fibers, found in muscles like the quadriceps, hamstrings, and calves for lower body activities, and the deltoids and pectorals for upper body movements. These fibers are more fatigue-resistant and are designed for prolonged activity, utilizing aerobic metabolism to efficiently produce energy. Endurance activities also engage core muscles to stabilize the body and maintain posture over extended periods. Overall, the key muscle groups are those that support sustained, rhythmic movements.
Cardiorespiratory endurance
The highest concentration of mitochondria in the human body is found in muscle cells, particularly in the muscles used for endurance activities like the heart and skeletal muscles.
