Anaerobic exercises are high-intensity physical activities that are performed in short bursts and do not rely on oxygen to fuel the muscles. Instead, they use energy stored in the muscles, usually lasting from 10 seconds up to 2 minutes. These exercises involve powerful muscle contractions that quickly release energy without the need for oxygen, leading to the production of lactic acid in the muscles. Examples of anaerobic exercises include weight lifting, sprinting, high-intensity interval training (HIIT), plyometrics (such as jump squats and box jumps), and calisthenics (like push-ups and pull-ups). The primary purpose of anaerobic exercise is to build muscle mass, strength, and power. Anaerobic exercise differs from aerobic exercise, which uses oxygen and is lower in intensity but sustained for longer periods. Anaerobic workouts are typically short but very intense and help improve muscle endurance, strength, and overall fitness.
