If you want to get stronger you need to make sure you are you are strength training and not exercising.
Most people I see at the gym are just exercising and not strength training. Most personal trainers I know have their clients exercising and not strength training. What’s the difference between exercising and strength training? Exercising is getting a workout in for the sake of getting hot and sweaty and chasing the pump whereas strength training is having an end goal in mind and coming up with a program that makes progress towards achieving that goal.
Strength Training is the process of accumulating the specific physiological adaptations necessary for improved strength.
If your goal is to get stronger then you need to be increasing force production on a weekly basis. That means adding weight to the barbell in a progressive manner. We do it 5lbs at a time. Numbers on the bar don’t lie. You are only getting stronger if the numbers are going up.
If you end your Friday with doing a squat for 5 reps for 100lbs and the following Friday you are doing 5 reps for 115lbs, then you got stronger. It’s that simple.
Strength training is a plan to make numbers on the barbell go up. If your numbers are not going up every week, then you are exercising and not strength training.
