Most people should aim for 5 to 15 sets of resistance exercise per week per muscle group to offset declines in muscle strength.

If you avoid resistance training, you will lose muscle size and strength, which negatively impacts your metabolism and posture.

Resistance training and cardiovascular exercise are both necessary for overall health, cognitive function, and maintaining muscle mass as we age.

Fitness is crucial for health, and while some people may experience muscle and bone loss, those who consume high protein and exercise regularly can mitigate these risks.

Muscle is vitally important for athletic performance and longevity.

To improve strength, you should perform anywhere from two to 20 sets per week, with five sets being sufficient to maintain muscle mass.

To get stronger, focus on progressively increasing the loads you move; for hypertrophy, aim for localized, intense muscle contractions, and moving weights in the 30% to 80% range of your one repetition maximum is the most beneficial for muscle hypertrophy and strength.

Exercise can maintain or even increase the size of certain brain regions, which may help ward off cognitive decline.
