Cardio still matters after 40, but a complete exercise routine has to do more than train endurance. Strength, balance, mobility and flexibility each affect a different part of how well you move as you get older.
Building and maintaining strength after 40 depends on what happens during the workout and throughout the rest of your week. Protein, energy intake, sleep, recovery, total activity, and changes in your health can all influence your progress.
Age can be part of the reason your health is changing, but it doesn’t tell you whether the change will stay minor, continue getting worse, or deserves attention. Sometimes waiting gives the problem more time to progress.
Protein supports much more than muscle, but maintaining strength is one of the biggest reasons it deserves more attention after 40. Learn how much you may need, where to get it, and why spreading it throughout the day matters.
