TuT is King

TuT being time under tension.

Talking about lifting weights - preferably light weights.  The heaviest weights I lift at my age (65 years old) are 30lb dumbbells.  And only on rare occasions.  My dumbbell weights of choice are 25lbs. 

The key is the time that the muscles you are exercising are under tension

The time you lift them up or one way, AND the time you relax the muscle(s) and put the weights “down” to the resting position. 

You should also fully extend the muscle making sure you do not hyperextend it. 

 Wishes for a great day to all
