It’s important to remember that there is no magic combination of rep and set schemes.
Rather, you should focus on finding the right number of sets and reps that allows you to continually lift more weight over time.
The ability to add weight to the bar, add a few more reps, or perform an extra set with great technique, is your reward from your last effective training session.
This is called “Progressive Overload“…
Progressive overload is not a goal in the Gym… rather a by-product of successful training sessions and sufficient recovery.
You can monitor your ability to “Present Overload”, that is, lifting more weight or reps, from session to session.
If you are able to “do more” this week than you were last week you are surely on the right path to success.
