Seniors can maintain fitness levels despite physical limitations by adapting their exercise routines to accommodate their needs. Engaging in low-impact activities such as walking, swimming, or cycling can help to improve cardiovascular health and maintain mobility. Incorporating strength training with lighter weights enhances muscle mass and stability, while flexibility exercises, like stretching and yoga, promote joint health. It's crucial to set realistic goals and listen to one's body to prevent injury. Additionally, participating in group classes or community programs can foster motivation and support while encouraging a sense of belonging in the fitness journey.
