I'm asked regularly about how heavy a person needs to lift to see results, high reps and low weight, or lower reps and heavier weight. Have you wondered this or asked a fitness professional?
Women generally do not lift heavy enough, neither do people 60 and over. The "reasons" are a woman does not want to look like a man, and older adults do not want to hurt themselves. I always try not to be overly critical when answering these questions, unfortunately, I know I am.
In a 2026 summary of studies called, "American College of Sports Medicine Position Stand. Resistance Training Prescription for Muscle Function, Hypertrophy, and Physical Performance in Healthy Adults: An Overview of Reviews", the results show you need to lift heavier than you think! The study surveyed adults over 18 years old who lifted 6-52 weeks per year across over 30,000 people.
Here's what the summarized results showed to elicit improved muscle strength, size, and multiple physical function outcomes:
Improved strength requires >80% of your 1 rep max load through a full range of motion for 2-3 sets, and more than 2 sessions per week.
Improved muscle size requires >10 sets per week and eccentric overload (slowing the down portion of your lift).
"Training to momentary muscle fatigue, equipment type, exercise complexity, set structure, time under tension, blood flow restriction, and periodization did not consistently impact training outcomes."
