Let's learn some fitness terminology:

Load: 50%-75% of 1RM (1RM refers to the maximum weight you can lift in one repetition)

Repetitions: Reach exhaustion within 15-30 repetitions (repetitions refer to the number of times, meaning you should do at least 15 times)

Sets: Up to 3 sets or determined by the time of circuit training (sets, for beginners, 1 to 2 sets are enough, not exceeding 3 sets)

Movements: The speed of each repetition is carried out in a 2:2 or 3:3 manner.
