Lactic acid builds up and that's why it starts to burn.
Lactic acid is formed by anaerobic respiration, and builds up in the muscles.
During exercise, lactic acid builds up in the muscles, leading to muscle aches. The lungs produce carbon dioxide, as they do at rest, and sweat is also produced by the body.
Lactic acid is produced by our muscles during exercise.
During a dumbbell raise exercise, the muscles primarily worked are the deltoid muscles in the shoulders.
During a lateral raise exercise, the muscles primarily worked are the deltoid muscles in the shoulders.
The primary muscles targeted during a lat raise exercise are the deltoid muscles in the shoulders.
The main muscles used during a squat exercise are the quadriceps, hamstrings, glutes, and lower back muscles.
During a deltoid raise exercise, the muscles primarily worked are the deltoid muscles, which are located in the shoulders.
The primary muscles used during a squat exercise are the quadriceps, hamstrings, glutes, and lower back muscles.
During a reverse hyper exercise, the muscles primarily worked are the glutes (buttocks) and the lower back muscles.
The muscles primarily engaged during the bridge exercise are the glutes (buttocks), hamstrings, and lower back muscles.
The primary muscles activated during a front lever exercise are the latissimus dorsi, core muscles, and the muscles in the arms and shoulders.
