Adjusting a fitness routine for injury recovery involves modifying exercises to avoid aggravating the injury while maintaining a level of activity. Focus should shift to low-impact exercises that promote healing, such as swimming or cycling, while avoiding high-impact activities. Consultation with a healthcare professional or physical therapist can provide tailored rehabilitation strategies. Incorporating flexibility and range-of-motion exercises is also critical to preventing stiffness. Gradual resumption of normal activities should be based on pain levels and professional guidance.
