Don’t rust up.
Maintain your independence through daily activities and accessible yoga adapted to suit ageing bodies.
The online media is full of ‘suggestions’ that “these 5 exercises is all you need to stay healthy” or a supplement that will ‘turn back ageing’.
NO such luck: - healthy ageing does require daily activity.
Simply standing up from a chair without using your hands, or twisting your upper body, several times a day will greatly improve your leg (upper) strength.
