Low Impact Resistance Training

Meaning

Low Impact Resistance Training (LIRT) is a specific exercise modality that utilizes external resistance to stimulate muscle hypertrophy and bone density improvement while deliberately minimizing joint stress and systemic inflammatory load. This approach is clinically favored for individuals with hormonal imbalances, such as high cortisol or low estrogen, where high-impact or intense training could exacerbate adrenal fatigue or joint pain. LIRT focuses on controlled, eccentric movements and appropriate time under tension to achieve significant musculoskeletal benefits without triggering a detrimental stress response. It is a strategic tool for metabolic and hormonal optimization.
