In a fitness context, the term "plateau" refers to a period where an individual's progress in strength, endurance, or weight loss stalls despite continued effort. This stagnation can occur due to the body adapting to current exercise routines, resulting in less effective training stimulus. Overcoming a plateau often involves modifying one’s workout regimen and incorporating variety to shock the body, such as changing exercises, increasing intensity, or adjusting nutrition. Addressing plateaus is essential for achieving long-term fitness goals.
