As you age, muscle mass and bone density can decrease, especially if the body rarely gets enough physical load. Resistance exercises such as lifting weights, squats, push-ups, or exercises using resistance bands provide mechanical stimulation to the muscles and bones. Muscles then adapt to become stronger, while bones also receive a stimulus to maintain their strength.
This exercise does not always have to use very heavy weights. What is more important is that it is done regularly and the load is adjusted to your abilities. The body needs gradually increasing challenges to continue adapting. If combined with adequate protein intake, good nutrition, and other physical activities, resistance training can be an important way to maintain body strength. For people who have certain health conditions or have not exercised for a long time, the intensity should be adjusted first.
