Final answer:
The term that describes a light-to-heavy system of lifting weights up to 6 sets of each exercise is called progressive overload. Progressive overload is a principle of strength training where you gradually increase the weight or intensity of your workouts over time.
Step-by-step explanation:
The term that describes a light-to-heavy system of lifting weights up to 6 sets of each exercise is called progressive overload. Progressive overload is a principle of strength training where you gradually increase the weight or intensity of your workouts over time. This means that as you become stronger and adapt to a certain weight, you need to add more weight to continue making progress.
By progressively increasing the load, your muscles are constantly challenged and stimulated, leading to muscle growth and strength gains. For example, if you start with a lightweight for an exercise, such as a squat, and perform 6 sets with that weight, you can progressively add more weight each week or training session to make the exercise more challenging and promote muscle development.
